How to correctly calculate sliding wardrobe doors - rules and calculation formula

Doors of this type are installed both in wall openings and in built-in cabinets. Therefore, installation systems may differ slightly. But in general terms, the algorithm of actions when calculating the parameters of compartment doors does not change. The technique is quite simple, and if you understand the meaning of each stage, you can do everything yourself, without turning to a professional.

Calculating the cabinet (if it is the one that is being assembled) is not limited to just determining the dimensions of the sashes. It is necessary to take into account its layout, calculate the optimal dimensions of compartments, drawers, and modifications of various components. For example, a roller mechanism. But that is another topic.

Preparation of the workplace

You need to start with this, and it doesn’t matter whether the installation of sliding sashes is supposed to be in a niche or a wall opening. It is necessary to ensure that the geometry of the selected area of ​​the room is correct, without distortions. Otherwise, calculating dimensions will not only become more complicated, but the result will also have large errors. In addition, the profiles will lie unevenly, and the compartment door leaves will roll spontaneously.

Programs

Programs are used for detailed calculations. They will need to be downloaded and installed before you can use them.

BT cabinet

The BT-cabinet program creates straight, corner and diagonal cabinets, where the model is built based on the entered dimensions.

First, the type of cabinet is selected, then the general dimensions are entered. Next, the space is divided into sections and the filling for them is selected - shoe racks, rods, shelves, drawers. The next stage is the selection and calculation of compartment doors. Their number is set, the design and appearance are selected - material and divisions, if necessary.

Dimensions can be easily changed directly on the model; to do this, you need to pull the desired partition or part. The filling moves together in sections and increases in length if the walls of the section move.

At the end, you can print calculations, drawings and a table with all the elements and parts with the number of pieces.

eXponent Furniture Designer

Another design program.

Its interface is entirely in Russian. As you enter the cabinet parameters, a 3D model is created. A large database of component elements (shelves, drawers, rods, holders and fastenings) is provided.

After completion, the drawing is saved in a separate file, and it is also possible to print directly from the program.

In addition, here you can create any piece of furniture and design your own room.

The official website no longer works, you can download it from Yandex Disk.

PRO 100

This is a program for creating both interiors and individual pieces of furniture. Completely in Russian, modeling by clicking the mouse and entering parameters. Lots of ready-made elements to choose from.

At any stage, you can change the parameters of sections, overall dimensions and filling. This will immediately be reflected in the price - the cost is easily tracked.

As a result, you can see drawings of models and individual parts in any projection with dimensions and method of fastening.

Basic cabinet

Another common program for designing cabinet furniture is Basis-cabinet.

When building a cabinet model, the program automatically calculates the dimensions of the internal filling elements and adjusts them if the general parameters change.

Simple and complex shapes and designs are available for modeling.

Libraries of fastening systems and elements in accordance with the products of popular manufacturers.

Sash size calculations

Height

To calculate this parameter of compartment doors, no formulas are needed. The initial value is the corresponding size of the opening (it is already known). Since the sash should not “fall out” of the profile, you need to take into account the height of its wall. If we focus on the Raumplus mounting system, which is most often used, then it is 45 mm.

It is enough to subtract about 40 from the height of the opening, and you will get the desired value. There will be a guarantee that the rollers in any case (dynamic or static) will not jump out of the upper guide. The maximum height is determined in the same way. Only the double thickness of the profile wall (top + bottom of the opening) is subtracted.

Using this method, the height of the sliding wardrobe is determined, regardless of the scheme according to which it is mounted. The algorithm of actions is identical for any constructions of this type.

Width

It should be selected so that the overlap of the canvases is ensured by an amount sufficient to install the selected type of handle.

How to calculate the dimensions of wardrobe doors

It is very important to calculate everything correctly and measure accurately so that the finished structure stands firmly in place. Any inaccuracy can lead to jamming or warping of the doors. The first thing you need to do is measure the width of the structure's platform.

When measuring, check the dimensions at several points.

The next step is to calculate the cabinet doors. We are interested in the dimensions of the opening for them, its height, width and depth. The last preparatory stage is to determine the number of leaves and the pattern of their overlap. The simplest design is with two doors and an overlay. Arm yourself with a calculator and start calculating.

Assemble a wardrobe compartment with your own hands for someone with practical skills, it is quite possible.

Measuring the opening

In order to place a closet in a room, corridor or hall, it is worth calculating the correct size of the opening. To do this, first select a location to install the structure.

Important notes to keep in mind when measuring aperture:

• To measure the hole correctly, you need to measure the width and height of the space;
• The smallest width of this type of structure is 50 centimeters; models larger than one meter can be found. The main thing is to calculate that there is enough space on the territory for all construction;
• Remember to measure the width of the space at the bottom and top, this will help you get an average;
• We recommend measuring the height, which is usually between 2 and 2.5 meters.

Necessary measures

Determining the number of doors

An obligatory step is the calculation of the cabinet doors. But in order to accurately determine the size, you need to take measurements from the hole where the clothing will be located. Its height, width and depth are taken.

For all measurements and calculations, certain rules must be observed:

• It is better to measure in different areas because there are differences;
• There may be an inch and a half error between measurements;
• the height value should be 4 cm less than the same value as the hole;
• It is essential that the calculations are made accurately;
• When measuring doors, it is advisable to take into account an important factor - the possibility of passing these elements through the openings of the living space.

For ease of opening the cabinet, a design with double wings is recommended. Selling products with three doors is common; they are quite wide and take up a lot of space. When choosing a product, you should first consider the available space in the room.

Recommended calculation formulas

The calculation principle is the same, but the number of leaves is taken into account. The initial value is the width of the opening.

• Wardrobe with 2 compartment doors. The overlap value is added to the result of measurements of the niche (opening), and the resulting value is divided by 2.

• Three-door design. The difference is that the number of handles and overlaps of the canvas increases. Consequently, the formula takes a different form. The calculation is made as follows: the double size of the door hardware is subtracted from the width of the opening, but the result is divided by 3.

Note
This applies if you want to calculate the maximum door width. As a rule, home craftsmen install so-called sash bumpers. And if their thickness is significant, then this value (multiplied by 2, since the installation of devices is done on both sides) will have to be subtracted from the obtained value. This will be the optimal width of the wardrobe.

Width and overlap of compartment doors

It is not recommended to make gates smaller than 500 mm: the gate will be unstable due to the proximity of the rollers. A little more force when opening and it may fall off the tracks.

Also, don't make the compartments too wide: they will be awkward to use. The maximum width is 1000-1100, but it is better to stay at average values ​​of 700-900 mm.

When calculating the width of a door, "good practice" is to avoid overlapping the interior space with the side profile. That is, the overlap of sliding doors must exactly match the width of the profile.

In this case, the thickness of the "dust cap" (schlegel) is usually not taken into account, leaving the choice - whether to glue or not - after the final installation of the front of the compartment.

If we take the width of the open door (asymmetrical profile, C) to be 25 mm, and the width of the closed door (symmetrical profile, H) to be 35 mm, then the formulas for calculating the width of doors 2, 3, 4 and 5 are conveniently presented in tabular form.

According to the calculation formulas for frame doors with the Aristo profile, it can be seen that the presence of a dust collector reduces the depth of the ceiling.

There is no exact calculation formula for frameless sliding systems. Usually there is an overlap of 20-30 mm, and the door width is rounded to an integer value.

Calculation method

To clearly understand all the nuances, let’s take specific aperture sizes as an example. Let's assume the main inputs are:

• Height Hpr = 2400 mm;
• Width Lpr = 2700 mm;
• number of leaves N = 3 pcs;
• buffer tape thickness B = 6 mm;
• number of overlaps A = 2 pieces;
• frame profile width C = 20 mm;
• The thickness of both rails is S = 40 mm.

When calculating, it is necessary to take into account the dimensions of the upper and lower tires of the housing. The top load-bearing lip is an inverted "W" cross-section.

The buffer strip can have different widths. The minimum thickness of the racks is 6 mm, and the maximum is 10 mm. This factor is taken into account when calculating sliding systems. In our case, the calculated strip thickness is 6 mm.

The profile of the handle determines the width of the vertical edges of the door leaf. The aluminum posts are slotted to hold the blade in place and are curved on the outside for easy hand grip. The thickness of the horizontal and vertical frame slats is the same, 20 mm.

Fill calculation

Doors for sliding structures are made of different materials - multi-layer plywood, chipboard, and sometimes high-strength glass. They all differ in thickness. But the calculation procedure for any filling of compartment doors remains unchanged. The basis for all calculations is the configuration of the profile for edging (that is, the features of its cut) and the standard dimensions of slab (sheet) products.

• Height. It has already been defined for the opening. All that remains is to subtract twice the thickness of the guide (top + bottom). When installing compartment doors, the seal is also taken into account. Its material has its own thickness, which must be multiplied by 2 and subtracted to obtain the desired value.
• Width. Also nothing complicated. If the filling is done in a metal “edging” (frame), then the thickness of the “ribs” is taken into account. Accordingly, its total value is subtracted from the calculated door width.

When independently assembling sliding structures, individual drawings are used, developed in relation to local conditions. The main thing is to understand the principle of calculating the size of doors, be it a wardrobe or doors in a wall opening. And everything else is just minor nuances that are not difficult to take into account. For example, the thickness of the divider partition, the design features of the handle, and the like.

Number of doors

The standard filling of a wardrobe opening can consist of 2, 3 or more panels that move relative to each other in a single plane. The vertical edges of adjacent doors overlap each other. This ensures that there are no gaps in the closed cabinet opening.

Installation of the sliding system can be done in two ways:

1. They purchase ready-made doors and install the wardrobe body based on their dimensions.
2. Having installed the cabinet, measure the opening. Calculations are made and, according to the results, doors are made.

In the second case, you will need a diagram for the workshop. You can also make sliding doors with your own hands, following our instructions in another article.

Purpose of the planks

A complete set of fittings for a sliding wardrobe door.

The sliding mechanism for wardrobe doors is combined into a single structure thanks to the use of:

• pens;
• edging profiles;
• connecting strips;
• guide profiles.

Curly strips allow you to open/close doors quickly, safely and quietly. The service life of the cabinet depends on their quality, reliability and material of manufacture.

Profile sizes can be very different.

Vertical and horizontal profile strips are used in compartment furniture . They may differ:

• according to the material of manufacture;
• sizes;
• color;
• price.

This must be taken into account when placing an order for cabinet production. If the profile is chosen incorrectly, the furniture will be uncomfortable to use, and it will not last long.
