A spiral staircase looks great in any environment, regardless of its styleA spiral staircase looks great in any environment, regardless of its style During the design and construction of stairs in a private house on the second floor with his hands is required to calculate the entire structure. Thus important parameters such as the step width, diameter, number. All this is very important to take into account to prepare the correct drawings and to make the entire structure, ergonomic and completely secure. This quite original design is very popular, since it does not require the construction of a large area, however, that the product has turned out strong and reliable, we must all be carefully considered and taken into account all the nuances. Furthermore, a great advantage of the spiral staircase is that it fits in perfectly with any interior and becomes a real decoration of it. It was convenient to walk the steps of the fan-type, it is necessary to identify their correct size. spiral twist is quite possible to make any brand, all depends on the design idea and the space available.


How to perform calculations of the spiral staircase to the second floor

Designing spiral staircases means by a determination of all required parameters of the product, and also drawing a schematic construction model designations. Scheme spiral staircase, regardless of its configuration must be performed in both vertical and horizontal projection. This will allow all the major draw the design details fully and to determine the advantages and disadvantages of each method steps arrangement.

Spiral staircase to the second floor should be not only beautiful but also functionalSpiral staircase to the second floor should be not only beautiful but also functional

Stairs can have the most different configurations, namely:

  • Building on the central axis;
  • Partial occurrence of steps in the central support;
  • With emphasis on the string side;
  • Cantilever arrangement.

Drawings of each type of ladder will differ among themselves, and this must be considered in the calculations and the preparation of construction plan. This dramatically different sizes of parts used for helical staircases since the fastening means to a certain extent take up a certain space for movement.


Functional spiral staircase: the drawings and the number of stages

Before you carry out the project of a spiral staircase, is worth everything correctly calculate and determine the number of stages. That is why, to be designed and erected structure on the basis of the data obtained.

For the construction of stairs you need to determine:

  • The number of stages;
  • The height of the riser;
  • The size and location of the stairs.

Number of steps in the staircase is determined depending on the length of its frameNumber of steps in the staircase is determined depending on the length of its frame



Initially, you need to determine the optimal number of steps. The ideal embodiment will 11-13 steps. Necessarily have to be an odd number for the greater comfort of movement. The countdown to go from top to bottom. The top step shall be to act as a platform, and its dimensions are no different from the rest of the available elements.

To determine the optimal height of the riser is necessary to divide the resulting distance from the ceiling to the floor and the number of steps. An ideal variant is the step height in the range of 15-20 centimeters.

For a spiral staircase most suitable winders that's why, to determine the optimal parameters, you must first prepare the drawing.

Calculation of the spiral staircase: Design Features

Spiral staircase consists of winders and is made predominantly of wood or metal. There are standard models of spiral staircases that can be done in the home or perform its original design, but it needs all correctly and accurately calculate and take into account the features of the finished product. Before proceeding to the construction of the structure, you need to choose the best type of product.

To the ladder was a practical, step width should allow to miss on it for two peopleTo the ladder was a practical, step width should allow to miss on it for two people

In particular spiral staircases may be:

  • rectangular;
  • polygonal;
  • Round.

Rectangular and polygonal structures can be used if the ladder is to be mounted against a wall. If it will be in the middle of the room, it is best to give preference to a circular design. Spiral staircases can be performed with or without risers. Staircase without risers are much easier to use, as the width of the winder stairs much narrower foot, so it may be slipping feet, if the riser is made, since it takes a certain amount of space.

Important! The absence of risers allows you to become fully the entire foot on the tread, so that the motion of a ladder would be more convenient and safe.

How to prepare a drawing spiral staircase

To prepare a drawing of a spiral staircase, it is important to correctly calculate all and to take into account the dimensions of each structural element.


Before you draw the layout, you need to consider:

  • Features of stages;
  • The width of the tread;
  • aperture size.

Before the start of construction of a spiral staircase should make its drawing on paper, specify the size of all the elementsBefore the start of construction of a spiral staircase should make its drawing on paper, specify the size of all the elements

After reviewing the available samples can be ready to choose the best option, which is then slightly change under the existing parameters and features of the house interior. One of the main characteristics of the ladder considered tread width. To determine this parameter is necessary not only to prepare the drawing, but also take a special formula that will help determine the required width of the stairs.

necessarily need to be displayed on preparing a plan:


  • External diameter;
  • Degree turn;
  • The width of the tread.

Additionally, in the calculations must take into account the place for fixing the stages, as well as a zone for the railing. In addition, it is necessary to take into account the required area for registration opening. When driving up or down a person of any height and should easily pass freely, without hurting the rafters. The optimum size of the aperture should be equal to equip about 2 meters. The minimum diameter is in the range of 1.2-1.5 meters.

How to make a calculation of the spiral staircase online

You can choose to carry out all the required calculations and measurements in the performance of the spiral staircase project. However, there are special programs that help to quickly and easily carry out the required measurements, make a drawing and visualize the resulting drawings. Thus, it will be possible to get a complete picture of how the finished staircase will look in the interior.

On the Internet there is a special program, through which you can perform the calculation of the spiral staircaseOn the Internet there is a special program, through which you can perform the calculation of the spiral staircase

In particular, this program such as:

  • Online calculator;
  • 3D Designer;
  • Autocad.

The most popular and the demand is considered an online calculator, and AutoCAD software. It is enough to make only the required data and the program will calculate and offer the most optimal solution. You can get a visualization of a finished design from all sides, as well as its sections, which will determine whether it will be durable and safe.

If we calculate in AutoCAD, it is worth remembering that the finished file will have the extension dwg, which is not compatible with all programs.

Carrying out the design of a spiral staircase

A spiral staircase installed in the main, if you want to save space.

Among the advantages of the spiral staircase should be noted the compactness and excellent aesthetic qualitiesAmong the advantages of the spiral staircase should be noted the compactness and excellent aesthetic qualities

It is perfect as a ladder on:

  • Second floor;
  • attic;
  • Attic.

To exactly and correctly perform engineering design, all the important requirements and standards GOST, as this will make a ladder strong, stable and secure.

spiral staircase project must be weighed very carefully to the last detail, to make it as robust and reliable. Ascent and descent should not bring discomfort. Materials for manufacturing parts have different strength and fully comply with the design loads exerted.

A spiral staircase is a excellent design and original form, so it can easily become an ornament of any interior completely at home, regardless of its stylistic features.
