Calculation of a metal staircase online calculator with drawings. Calculation, design and optimal dimensions of stairs to the second floor: how to do it yourself, what to look for

To make the staircase comfortable for use, it is necessary to fulfill many requirements for its design and shape. It is also important to calculate the stairs for safety reasons, because it must withstand all the loads placed on it. Dimensions may vary depending on their location and room parameters. In this article, we will provide you with information on calculating the dimensions of stairs with all acceptable standards.

Why is it necessary to calculate the stairs

During the design phase of a house, a lot of calculations are performed, but we are only interested in those that relate to stairs. The calculation of the stairs to the second floor in an apartment or house must be performed primarily for safety reasons and to save effort and money.

Performing calculations helps determine:

  • how much material is needed for construction;
  • what loads must correspond to the materials to give required strength designs.

Regardless of whether it will be a staircase to the 2nd floor, to the attic, to the basement or viewing hole in the garage, carrying out calculations will help not only do the job correctly, but also protect against injury, eliminating the possibility of structural damage.

How to calculate the stairs to the second floor

Using, which you can find on our website, is one of the easiest ways to calculate.

Also, for the calculation, you can use the formulas from this article.

Ceiling opening size

The calculation of the ceiling opening must be performed in order to avoid inconvenience during the operation of the stairs. The distance from the stairs to the edge of the ceiling opening should be such that a person does not need to bend down when descending and ascending.

Ceiling openings are classified according to the form of execution and are divided into:


The width of the march to the 2nd floor will depend on the functionality of the stairs:

  • For safe use the width of the span should be at least 90-100 cm.
  • To transfer furniture between floors and for a calm divergence of two people in the opposite direction, a width of 125-150 cm is required.

The length of the kosour or bowstring

In order to determine how long the bowstring (kosour) should be, you must use the formula

a 2 + b 2 \u003d c 2,

where a is the length of the march; b - the height of the stairs; c - the length of the bowstring (kosour).

The calculation of the stairs in a private house can be started by determining the number of steps, it will be convenient to use the table below. It shows the dependence of the number of steps on the height of the stairs and risers. Dividing the height of the stairs by the height of the riser, we get a number, rounding which, we get the desired number of steps.


The size of the riser depends on the angle of inclination of the structure. The figure below shows optimal angles tilt for different types stairs and ramps. The optimal angle of inclination in residential premises is 24-37°, which corresponds to approximately 140-180 mm, in the figure the area is highlighted in green.

To determine the step width, it is more convenient to use the formula shown in the figure, the dependence of the step width (600-640 mm) and the height of the riser. There are a number of restrictions that must be adhered to when calculating:

  • the edge of the tread should not hang down more than 50 mm;
  • the width of the tread should not be less than 100 mm.

The width of the steps based on the formula is: 600 - 2 * 160 \u003d 280 mm.


In the event that the width of the steps is less than the calculated one, this will lead to big problems when descending due to the fact that the foot will not fully stand on the step.

On what the parameters of the steps can depend

The main parameter on which any straight staircase, turn or spiral depends, is the size of the room in which it is located.

When not very large area the room in which it is necessary to fit a straight single-flight staircase will have to change the angle of inclination of the structure to a steeper one in order to reduce the length of the bowstring. Changing the angle of inclination directly affects all the parameters of the steps, except for their length, the dependence is shown in the figure.


To save optimal height riser it is necessary to reduce the width of the step.

Calculation of the angle of inclination of the stairs

Depending on the angle of inclination, the stairs are divided into:

  • ramps - angle of inclination up to 30 °;
  • For residential premises - a slope of 30-45 °;
  • 45-75 ° - attached, steep;
  • more than 75 ° - evacuation, fire.


Knowing the principles of calculating the angle of inclination of the stairs, you can design and build a comfortable staircase.

Features of the calculation of turning stairs

There are a number of ways. The calculation of a U-shaped staircase is practically no different from the calculation of a staircase with a 90 ° turn.

by the most in a simple way calculation is the method of proportions, you can find options for calculations by other methods on our website. You can also use the construction calculator of our site to calculate U-shaped and L-shaped stairs.

Graphic method

The method is based on the proportional placement of steps at the turning point, the calculation of stairs with a turn of 90 and 180° is identical. Consider, for example, the calculation of a U-shaped staircase:

  1. Draw a staircase (top view) on a scale with the designation of the extreme steps to the turn and the central turning post.
  2. Draw an axis in the middle of the stairs (in the center of the support column).
  3. On both sides of the axis, you need to draw an equilateral right triangle.
  4. We divide the hypotenuse of the triangle into 3 equal parts.
  5. We connect the central turning column with the marks on the hypotenuse with lines, as a result of which each of the sides, separated by the axis from paragraph 2, is divided into 3 parts.

Features of the calculation of spiral staircases

Principle d is in many ways similar to the calculations of simple marching and turning stairs, but, of course, there are points that should be paid attention to due to design features.

When making a spiral staircase to the second floor with your own hands, you should be aware that there are certain limits in the size of spiral staircases, beyond which it is not advisable to go for reasons of safety and ease of use:

  • step depth in middle line not less than 200 mm;
  • at a distance of 150 mm from the support post at least 100 mm;
  • in the wide part at the edge no more than 400 mm;
  • ladder diameter from 1300 to 3300 mm;
  • march width from 530 to 1430 mm;
  • opening diameter from 1300 to 3300 mm.


Consider, for example, the calculation of a spiral staircase for a room with a height of 2700 mm and a march width of 1000 mm.

  1. It is necessary to calculate the diameter of the future staircase and, accordingly, the diameter of the ceiling opening. The main thing when calculating to double the width of the march is not to forget to add the diameter of the central support column, with such a width of the march it should be at least 200 mm. As a result, we get: D \u003d 1000 + 1000 + 200 \u003d 2200 mm. This size falls within the parameters described earlier.
  2. Let us determine the radius of ascent, which is equal to the sum half the width of the march and the radius of the support. Rn=500+100=600 mm. We take half the width of the march due to the fact that in the middle of the span the most optimal width tread, which is 200 mm.
  3. Knowing the radius of rise Rn=600 mm and the width of the tread 200 mm, we determine the number of steps per one turn of the stairs using the formula: L=2πr/200=2*3.14*600/200=18.84. Rounding the resulting number, we learn that one turn consists of 19 steps.
  4. To calculate the height of a step, it is necessary to determine the distance between the turns of the stairs. Consider an example of the use of stairs by people whose height is not more than 180 cm. In this case, the distance between the turns should be at least 200 cm. Thus, we determine that the height of the steps is 2000/19 = 105 mm.
  5. The number of steps for our room with a height of 2700 mm is 2700/105=26 pcs.
2000/160=13 pcs

steps, and, accordingly, on the entire staircase:

2700/160=17pcs

This option will be more economical, due to the fact that the entire staircase will require 9 steps less.

Which of the options to use is up to you. The difference is that the climb spiral staircase steeper than on a simple march, and the use of less high steps makes it easier to climb.

How to calculate the attic stairs in the house

An attic folding ladder is calculated in the same way as a simple attached ladder, based on the fact that the angle of inclination is 65 °. To determine the length of the stairs, you must use the formula.

Staircase may be original

The staircase structure in the house is a necessary part that connects the floors. Choosing a ladder design is not as easy as it seems at first glance. The house needs not just an element for descent and ascent, but a convenient and aesthetic structure.

The selection of a ladder structure is not an easy task. Before you stop your choice on any model, once again return to the project and layout interior spaces. It is quite possible that you have overlooked some important aspects: where the flight of stairs will go, how many there will be, whether the chosen model fits the design of both floors and many other questions.


Different types of staircase design: photo

We invite you to familiarize yourself with different options design solutions for staircase structures. Before you start learning programs for calculating stairs, consider appearance designs. To do this, we present to help you photographs showing successful decorative structures.





Don't rely too much on fashion trends. The focus should be on the style of your home itself.

Main technical parameters of stairs

Any building has its own standards. There are such norms for stairs. If you deviate from them during construction, using the structure will be inconvenient at best, and simply dangerous at worst. The list of parameters includes the height of the riser and the width of the steps of the stairs, the slope, the height of the railing.

The dimensions of the steps of the stairs take into account the allowable height of the riser, which is 80 mm: the minimum value is 120 mm, the maximum is 200 mm. The depth of the tread is made between 235 and 355 mm. The angle of inclination depends on several factors, but the acceptable values ​​​​are 24-50 °. If the slope exceeds 45°, then the steps become too steep and uncomfortable. Proper slope forms the height of the rise in a certain ratio to the width of the tread.

The choice of arbitrary values ​​can violate the technical qualities of the design. In addition to the above parameters, they take into account the dimensions of the stairwell, the length of the march, the number of lifts (preferably no more than 18), the total distance from the floor of the first floor to the second.

On average, the step length of an adult is 63 cm, and when lifting, this number becomes 30–32 cm and increases or decreases depending on the slope of the march. As for the fence and railings, the standard indicates 90-120 cm. The critical height of the stairs is also an important parameter, therefore, in the plan of the house, it is worth considering the height of the ceiling of the second floor to prevent head injuries. Finally, we add that the ladder that is able to withstand weight up to 250 kg, and the railing - over 100 kg, will be safe.

The main types of stair structures

You can rejoice at the variety of staircase designs. Their main types are taken into account in programs for calculating stairs. The convenience of mid-flight lies in their practicality, spiral staircases - in their sophistication and elegance, as well as economy usable area. The advantage of combined structures is successful combination elements of all other structures and maximum level interior solution.

Mid-flight staircase Spiral design Combination of elements of all designs

Stair structures take into account load-bearing elements, namely stringers, which can be one or two, bowstrings, bolts, a combination of elements. Do-it-yourself calculation of stairs to the second floor can be a difficult task when designing complex structures. It is important to remember that any calculations must be based on building codes for your convenience and safety.

The main materials from which ladders are made, and the nuances of their calculation

The use of any material must be selected taking into account building codes. The ladder structure has a weight that should be included in the design. Each design is individual, this is emphasized not only by the features during construction, but also by the choice of material for its construction. So, what materials for the manufacture of stairs are especially popular:

  1. Tree is in first place. Wood is a traditional raw material for any structures. The aesthetic qualities of wood and its specifications at the highest level.

  2. Stone almost as popular as wood. Stone structures serve for decades without changing their original appearance and without needing painting.

  3. glass stairs are in demand in modern designs home interior. Glass is perceived easily, although its technical characteristics include strength and considerable weight.

  4. iron structures can be simple and massive, or can become a real work of art thanks to forged elements.

  5. Reinforced concrete stairs add grandeur to the design.

Many designers do not follow the canons, and boldly combine various materials, combining everything in incredible proportions. Of course, the cost of such a staircase increases not only due to the work of the designer, but also because of the difficulties associated with the construction process. And, of course, do not forget about combined options when part is made of metal, and part is made of glass or wood. Some designers even embark on bold experiments, combining wood, metal and stone. As a rule, such structures are installed in rich houses.

Calculation of wooden stairs

Tradition and classic - that's what we can say about wooden stairs. These are trendy designs that fit into many styles in design. Wood needs to be treated, as this material is prone to rotting processes, termite attacks and is not fire resistant at all. A wooden staircase will organically fit into the house from any combination of wood. This will be the best and environmentally friendly option. A combination of different types of wood, a special texture, aging and varnishing are welcome.

The most popular stairs in the construction of houses are structures made of pine, beech, oak and ash. The program for calculating wooden stairs differs from others precisely in the qualities and properties of the material.

Calculation of metal stairs

This material, cold to the touch, was not previously on the list of popular ones and was used in office flights of stairs. But it is almost impossible to resist a variety of curly designs with exquisite patterns, bronze elements.

Metal stairs to the second floor can also be calculated online using special calculators.

Determining the required geometric dimensions of the stairs

So, before you open the calculator for calculating the stairs to the second floor online, carefully calculate all future parameters. Without the dimensions of the height and width of the steps, the fence, the distance between the floors and the angle of inclination, the program will not produce any results.

An example of calculating the length of the stairs, the height and width of the steps

We remind you that all staircase parameters comply with SNIP and GOST standards!

We point out only the most basic points that play a role in the safety of people operating the staircase. This list includes total number steps, which can be from 3 to 18, regardless of parity. The height of the steps should not be less than 12 cm, and in no case exceed 20 cm with a total width of 23-25 ​​cm.

Approximate drawing of a straight staircase

Let's try to model a marching staircase on stringers. Given: landing, length - 6000 mm, width - 3000 mm, height between floor levels - 3300 mm, distance between marches - 100 mm. We make a calculation in which we take into account that with a distance between floors of 3300 mm we make two marches.

So, (the width of the landing is 3000 mm - the mid-flight gap is 100 mm) / 2 = 1450 mm. To determine the height of one march, we divide the interfloor height in half and get 1650 mm. The size of the steps is defined as 150 mm height multiplied by 300 mm.

The number of risers in a march is calculated by dividing the height of one march by the height of the riser and get: 1 650 / 150 = 11 (pieces). The upper march will have one step less, 11 - 1 = 10 (pieces), which means that there will be 11 risers in the march, and one less tread. The length of the march is calculated by multiplying the width of the tread by the number of steps, multiply 300 mm by 10 pieces and get 3000 mm.

The standard value of the width of the stairwell is 90 - 110 cm, although in rare cases it is permissible to reduce this mark to 80 cm. All dimensions on the plan and drawing must be transferred to the walls and all components of the structure must be noted. To do this, use a plumb line and a lined cord.

Determination of the required angle of inclination of the stairs

Many recommend a tilt angle between 29° and 37° as larger angle although it saves space, but only due to a decrease in comfort. In the calculations, do not forget about the location of the door and window openings, columns, arches.

Calculation of stairs of various types

If after all of the above independent calculation all the nuances of the staircase design seems to be a complicated matter, then you can not risk either the safety or the quality of the future structure, but trust a special online staircase design program. When calculating stairs of any type, you will need to enter a lot of your measurements. The program offers a calculation for all types of stairs, no matter if you want a spiral structure on stringers or a ladder with winder steps.

All data is automatically processed and a drawing with all the exact parameters is produced as a result. The output data includes information about the materials spent on the construction of the structure. Programs that offer 3D visualization are especially interesting, since you can not only get a drawing and the required amount of material, but also work on a design.

With 90° winder steps

Unique modern layout or small size houses often add complexity when choosing standard staircase structures, a straight staircase will not fit everywhere, as well as platforms for rotary structures. The solution was found in the process of architectural searches for a new good option. As a result of the need, stairs with winder steps arose. Such structures solve the problem of moving between the first and second floors for any layout and spatial volumes of the premises.

Please note that due to this design, there is a significant saving of usable space with an external elegant appearance.

Such structures are not traumatic, since all staircase parameters must be observed during construction. The usual material in the manufacture of such L-shaped ladders is wood or metal, mainly aluminum. Exactly this practical solution for the construction of a compact interfloor connection. Here are more options for such staircases.


With 180° winder steps

The design of such a ladder is called U-shaped because of its external resemblance to this letter when viewed from above. Two straight flights of stairs are connected by a small platform convenient for passage. A U-turn is made on it, and the movement begins in the opposite direction.

This option is also in demand and popular with architects and designers. This is a very convenient transition between floors, which can accommodate a very small space. Designers have tried and carefully worked in this direction, making such designs very stylish in the interior. When calculating this design, you need to pay attention to the height between floors, since incorrectly calculated parameters will make moving up and down extremely inconvenient due to hitting the ceiling with your head.

Straight ladder

This is the most traditional type of stairs, where all parameters are closely interconnected. The angle of inclination plays a big role. The width of the steps and their height depend on it, which decrease or increase depending on the change in the value of the angle of inclination.

But in any numerical scenario, the length of the entire staircase will be rather big - 3-6.5 m. This value depends on the combination of all parameters, including thickness interfloor overlap. The calculation also includes taking into account the length of the platforms in front of the entrance and exit to a direct march. Thus, the length of the staircase increases even more, and usable space is lost. The minimum length of the platform in front of and after the stairs is 80 cm and must be identical to the width of the stairs.

A two-flight staircase on stringers with a 180° turn. online calculator

With a large distance between floors, a two-flight staircase structure is installed. Another platform will not only change the direction of the ascending or descending one, but can also be endowed with other functions, because it is a support for the entire structure. A variety of two-flight stairs are taken into account in the calculations.

The owner should decide whether the design will be open or closed type. At open type the gaps between the rises will be visible, and when closed it will be safer to climb, because such ladders have deaf risers. Platforms can be single-level or two-level, where there is an additional step. The design itself can be clockwise or counterclockwise or just straight. Our calculator will help in calculating such a design.

Three-flight staircase on stringers with a 180° turn

This design is similar to the letter "z". Three marches are obtained at the expense of two intermediate platforms, and the middle march is noticeably shorter than the others. The size of the platforms should not exceed the width of the steps. Such landings are convenient for many people, especially for those who find it difficult to immediately run up the stairs.

To do correct calculation, take into account the height of one march. To do this, the interfloor distance is divided by 3 and all risers and treads are calculated in one march with a step size of 300 × 150 mm. Take into account the height of the march and steps, as well as a smaller number of treads by one, due to the location of the last tread on the second floor landing. Typically, this design is used in houses where the interfloor distance is over 3 m.

Calculation of a spiral staircase

Beautiful and practical design saves space and is a great decorative element. Such a ladder can be chosen for any style. The design is complex in its form. Its numerous wedge-shaped winder steps should be located at a certain radius.


There are four types of such stairs with their own characteristics: with or without support on the walls of the house, with or without a supporting pillar. The calculation includes the angle of rotation (270°−360°), ceiling height (2 meters or more), step end width (from 40 cm) and narrow end width (from 10 cm).

Straight staircase on bowstrings

The classic type of construction is especially popular in office buildings. The difference from the stairs on the stringers is the insertion of steps into the grooves, called the bowstring. Such designs are open and closed, the difference lies in the use or absence of risers. It can be single-flight or double-flight ladders with any form of landings.

Programs for calculating stairs online. Calculator with drawings

In the presence of programs for design, you can still experience difficulties in calculations and drawings. Therefore, our editors offer a calculator where you need to enter indicated values and get the result. Building drawings will help adjust the wishes of the owner of the house. If you have already chosen the design option and material, then the most important thing remains - to correctly measure all the parameters of the future staircase. All data after entering into the table windows will be processed, and you will see the result.

Where to order the manufacture and installation of turnkey stairs - prices, catalogs

Numerous companies specializing in the construction of stairs offer their services not only for the construction phase itself, but also for various design solutions. You can find many interesting offers from designers and manufacturers.

The price of an L-shaped staircase with a 90 ° turn made of different types of wood with a minimum opening of the second floor (920 × 2700 mm), an inclination angle of 42 ° and 15 steps costs from 35,000 to 150,000 rubles. Prices for spiral staircases start at 55,000 rubles, although some manufacturers offer to purchase a finished metal spiral staircase for 40,000 rubles. The cost of a U-shaped staircase also depends on the material and starts at 90,000 rubles. The price of the selected staircase will depend on all the parameters, material and installation.

If you have any questions, please write them in the comments.

Most often erected two-story own houses. Some get houses and more storeys. But all houses are united by the fact that stairs are thought out even at the design stage. The latter serve not only as the main passage to the upper floors, but also as an important attribute in the interior.

The main criteria by which the material is chosen and the stairs are built are safety, convenience, long term service and aesthetic aspect. To correctly calculate the size of the stairs, its steps, you must have the exact dimensions of the room where all this beauty will be located.

The dimensions and quantity of building materials for a wooden staircase depend on its design (straight, with turns, spiral, etc.). To calculate a wooden staircase online, select the desired calculator:

If the room allows, then swing-type stairs are constructed. They are suitable for a solemn and slightly pompous interior. In it, a swing staircase will emphasize all the advantages. But most often they install a narrow single-span staircase, which takes up little space, but also decorates the room.

Straight wooden staircase on bowstrings

Wood is considered the most demanded material, because any products made from it give the room sophistication and comfort. With proper care and varnishing, a wooden staircase will last more than one year. The main thing is to make sure that fire does not reach it, because the tree has a significant drawback. It quickly submits to fire, which can destroy the stairs.

Wooden staircase with 90 degree turns and flat landings

Most important element ladder construction - step. If you design them on time and with high quality, then this will save the owners of the house from many troubles. counting required amount steps, strictly adhere to several rules.

First, the size and height of all steps must be the same. Secondly, the construction of a staircase with three steps is allowed, but no less. The maximum allowed number of steps is eighteen. When designing a house, calculate the acceptable slope of the stairs. It is at least 30 degrees.

Wooden staircase with turning steps

The steps are made the same width as the width of the human foot. Then the household will not have to tiptoe up or take extra steps. There is a publicly available formula for calculating the width standard stairs: a=45-b.

In the formula, a is the tread width, b is the riser height, and 45 is the ideal sum of the two. Winder and rotary steps are calculated using this formula only partially. The formula is suitable for calculating the width of a step right in its middle. Another 10 cm is added to the results obtained. When constructing a staircase, first of all, attention is paid not to compactness, but to comfort.

Stairs are an important and responsible attribute in every home. They must provide comfort, reliability and safety for every resident. It is desirable that the staircase structure takes up little space in its area. And in order for it to meet all standards, you need to design it correctly.

How to calculate a ladder: the basics

The most common material for the manufacture of stairs is wood. It is considered the "warmest" and pliable material, which should be handled very carefully. The most common types of wood are beech, oak, ash, birch, larch and pine.

To make calculations for any type of stairs, you must first determine three dimensions. First, you need to determine the level of the clean floor and then measure the height of the structure along the wall from it. Secondly, its length should be measured, starting from the wall and ending with the expected completion of the span. And thirdly, you need to find the length flight of stairs by resorting to the Pythagorean theorem. In this case, the lengths of the legs are the found dimensions of the height and length of the stairs; in this case, you need to find the hypotenuse of the resulting right triangle, i.e. march length.

To make it comfortable to walk up the stairs, the depth of the steps should be about 30 cm, and the height - about 16 cm.

Knowing the dimensions of the steps, it is necessary to divide the length of the flight of stairs by these dimensions, and their number will be obtained.

For convenience, you need, the width of which is at least 80-90 cm. If it is intended for household purposes, i.e. leads to the basement, then it is better to make it about 120 cm. If the structure is directed to the attic room, then it can be made narrower, about 70-80 cm.

Should be 40-45°. The most comfortable is the ladder design, which is inclined at an angle of 45 °. But due to the fact that it takes up a lot of space, it is rarely used in construction. You can choose and sharp corner slope of 30-36 °, especially since such a design will take no more than two meters on the floor. Climbing up this setting will be convenient, and you can only go down backwards due to the steepness of the slope.

Stair calculation

Required:

  • selected low knotted wood for bowstrings.

Let us consider in more detail how to correctly calculate. Any staircase design consists of marches and platforms. It is important that the width of the platforms is not less than the width of the march. Marches consist of steps and bearing beams, which are called bowstrings or stringers. They are made from thick wide boards, the cross section of which is 80-100x200-250 mm, or made from two narrower boards.

Steps consist of treads and risers, the width of which should be correctly calculated. The steepness of the stairs, as well as the convenience of walking along it, is determined precisely by the ratio of their sizes. It is necessary that the person's foot should completely stand on the tread, i.e. this is an average of about 30 cm, and the step length was on average 60-70 cm, which means that the height of the riser is 14-16 cm. In this case, the following formula for calculation applies: the sum of two risers plus the width of the tread is equal to the length of the average step of a person. Given the thickness of the tread of 3 cm, it turns out that one step occupies 30 cm horizontally and 15-18 cm vertically.

The resulting numbers are necessary to calculate the stairs for the house correctly. Let's give an example, if the height between the first and second floors is 3 meters, and one step is 30 cm by 15-18 cm, then you get 17-20 risers. In this case, the last step is the floor on the second floor. Next, you need to divide the height of the ladder structure by an integer in this range. It is better if it is even, and it turns out exact height steps, consisting of the thickness of the tread and the width of the riser. Let's say you need to make 18 steps, then the height of the step will be 300:18 = 16.7 cm. This design should be divided into two flights of stairs and be sure to make it with a turn.

How to make a turn

In a staircase, a turn can be done in three ways. One of them is for the spiral staircase, which is one big turn. It is very compact and takes up little space, but has a fairly large steepness. Since in one turn of 360 ° the stairs must rise at least two meters, the span should have from 13 to 15 steps. Due to the design, the width of the tread should be small, so the steps at the spiral staircase are narrow and high. It is best to install it either in the attic or in the utility room.

Marching stairs need to be rotated 90 ° or 180 ° using platforms, or you can use special steps in the form of a trapezoid. A horizontal landing is arranged if the area allows. Such a staircase consists of straight elements and has classic look. On the site itself, you can make a window, which will add elegance and additional lighting during the day. If this is not possible, then the turn of the ladder structure must be done directly with steps. In this case, in a certain place, maybe not in the middle, you should start installing treads in the form of a trapezoid, which set the turn of the stairs by 15 ° or 30 ° for each step. As a result, they turn it to the desired angle.

Using an online calculator for calculating stairs is not at all difficult if you understand the instruction manual and enter the necessary parameters correctly. Calculating the stairs to the second floor using a calculator is very simple, and you can do this from any device with Internet access, for example, a tablet, computer, and the like.

The ladder must be strong, stable and properly thought out. In order to determine the size of the stairs in a private house, it is worth considering the space between floors or, in other words, the thickness of the interfloor slab. Initially, you need to decide on the shape of the structure. It is quite possible to equip a building for lifting with your own hands, but in the absence of special professional skills, you should choose the most normal version straight stairs.

It will be reliable, convenient, and building process won't take much money or time. On average, such a staircase is suitable for rooms with a ceiling height of 2.5-3.5 m.

For the convenience of this piece of furniture, it is necessary that the flight of stairs be located on racks, and there should be free space under it. Thus, it is possible to use square meters under the shelves, the placement of dark rooms and similar objects. To make the calculation correctly and independently, you need to use a simple and convenient formula, or in other words, just take the optimal proportion - 2/1 relative to the length of the flight of stairs and the height of the room. For example, if the height of the stairs is 3 m, then the length should be 6.

To calculate the slope parameters, you need to rely only on personal preferences. Experts suggest choosing the most optimal tilt angles - 30 and 40 degrees. If the steepness is less, then the size of the length will be very large, and in height it will look short.

What is a ladder calculator online

Now many have begun to use the computer method of calculating the parameters of the stairs online. The program can be installed on an Android smartphone or on a laptop with any operating system. An example of recalculation is in each application together with instructions for using the program.

In general, the development is quite convenient, functional and it does not take too much time to calculate the required amount of material, width, including determining the slope.

The calculator table contains various columns and rows, each of which has a specific purpose. There is a calculator that designs the structure. In particular, by entering certain data into the table and pressing the desired button, you can get an image of the future design in a couple of seconds.

The drawing will consist of:

  • Side and top view;
  • Step drawing;
  • Bowstring drawing;
  • Initial data.

Using the calculator, you can discover many new features that will greatly simplify the development of the project. It is possible to calculate and model a staircase on bowstrings, to carry out the most accurate calculations of structural details, to obtain a diagram of a staircase in at its best and calculate the required amount of materials.

How to calculate the stairs to the second floor in a private house

The methodology for calculating and developing an ordinary staircase is very simple and you can do it yourself. Namely, to design a staircase in your home, you need to accurately measure the ceiling opening. In particular, its width and length, including the height of the ceiling.

Ladder planning should be carried out taking into account:

  • Dimensions of the future structure;
  • Interior and general style of the room;
  • Use of a specific type of materials;
  • load;
  • The direction in which the movement will be carried out;
  • The need to install an additional support.

In any case, regardless of what types of materials will be used, the calculation of the staircase structure is carried out from room measurements. If the construction of the stairs is carried out at the time of repair, then it is worth considering how the room will change, because the walls often thicken, or the ceiling decreases slightly. The dimensions of the stairs can be affected by the finish of the floor, the ceiling and other surfaces in the room.

Key parameters of the staircase calculator

Thanks to modern technical developments, it has become much easier to build houses, determine the location of pipes and stairs in the entrance, and more. Now everyone can independently make a 3D modeling and examine the future staircase almost from the inside.

It is through a computer that you can:

  • Eliminate errors in the calculation;
  • Correctly build a ladder, taking into account the norms and standards of SNIP;
  • Make the stairs comfortable and convenient even at the construction stage.

There are a huge variety of programs and each has its own type of interface, features of entering parameters and similar characteristics. It is worth noting that improved application models help to calculate even such trifles as the amount of fasteners.

Before you use the calculator to calculate the stairs, as well as to form its drawing, you need to decide:

  • With the location of the structure in the house;
  • Overlooking stairs;
  • With material.

In general, if the project is simple, then the calculation will not take much effort and time, because a direct structure can be installed anywhere in the room.

The standards for the design are the simplest, among which should be taken into account:

  • Safety;
  • Reliability;
  • Convenience;
  • Comfort.

Even when erecting a staircase in a private house, it should be borne in mind that it will have a great impact. For example, furniture, construction and Decoration Materials and corny will rise a large number of people, children can run and so on. That is why the ladder should be made as stable as possible and preferably with additional props.

For compressed spaces and to save space in the room, you can use a spiral staircase.

It is worth noting that there are also staircase structures, which are divided into two-flight and one-flight. They have large dimensions and are not intended for small rooms. Be sure to think not only the base and the middle of the building, but also the exit to the second floor. The exit or location of the hatch should be convenient so that there are no overhanging structures. For example, the sloping attic roof. This can cause serious head injury and more serious consequences. It is advisable to equip a platform with a railing at the top, which will protect the descent and make it more comfortable.

Rules for using the program: how to calculate the stairs correctly

The calculation of the rise to the top should be the most correct, regardless of what the staircase will be: straight, angular, vertical.

Other parameters are also not so important, for example:

  • What entrance platform will it be equipped with;
  • Is it convenient to wash the structure in the future;
  • The use of which array will be carried out during construction;
  • Will the structure be wooden or using metal shields.

The most important thing is that the structure must be safe and comfortable, as this can affect the health of those who will use the structure.

For example, stairs that are too steep and slippery steps can cause injury.

It is in order not to spoil the future structure for lifting up that it is worth using special programs that take into account all the nuances, including the size of the march, the height of the opening, and similar parameters.

Calculation of stairs to the second floor: screw design

Spiral staircases can have a rotation of 180 degrees.

These designs:

  • Stylish;
  • Beautiful;
  • Compact.

It is the spiral staircase that is ergonomic and practical way through which you can get to the second floor from the first. In addition, such structures are often chosen because of their aesthetic appearance, as they will look perfect in modern style or high-tech.

To calculate the diameter of a spiral staircase, you need to multiply parameters such as the width of the march by 2, and then add the diameter of the base.

To determine the radius of the rise, you need to divide the width of the march by 2 and add the radius of the support legs. To make the staircase as comfortable as possible, you should not make it less than 800 mm. Thus, it will be possible to move without problems. With regards to the number and height of steps in a spiral staircase, they must be calculated so that one person can freely climb / descend and, if necessary, turn around on it. The height of the rise space is calculated by adding the average height of a person - 180 cm and the average depth of the tread - 20 cm. Then all this is divided by how many steps one turn has. Then the height of the stairs is divided by the value that is obtained.

Stair calculation program

The formula for calculating stairs depends on the type of structure, height, width, number of steps and material. For a private house, you can choose stairs different kind. In particular, curvilinear, for example, helical, angular and from different material. It can be metal, wood, as well as plastic, but on a wooden or metal base. As mentioned earlier, screw structures are compact in size and add aesthetics to the interior. Also, the calculation of the stairs is affected by the room and its features.

In particular:

  • What it is used for;
  • What parameters does it have;
  • What is the interior in it;
  • How many turntables are needed;
  • What should be the configuration of the steps;
  • Where will the stairs be located?

Self-erection of stairs is a very interesting activity, because you can connect your imagination, it’s not easy to do metal structure, but the original forged model. There can be a huge variety of options for finishing and construction, but the main thing is to choose only proven methods of calculation. For example, special online calculator.
