How to calculate wardrobe doors without incomprehensible online diagrams and calculators? Calculation of sliding wardrobe doors for self-assembly: formulas and programs Calculation of 3 sliding wardrobe doors

The wardrobe door is a simple mechanism only at first glance. To make and install it yourself, it’s not enough to buy everything you need. It is necessary to correctly measure the connector and calculate the necessary indicators. This will take time and patience. Correct calculation is half of the positive result, a guarantee of successful service and maximum benefit of the design.

How to calculate the size of the door leaf for a sliding wardrobe

First of all, indicators such as the height of the opening and its width are measured. Be sure to measure with a level so that the guides do not tilt - if they are not adjusted, the sashes may roll down.

The height of the slats themselves along which the canvas will move is about four centimeters.

First you need to determine the height of the ceiling (standard height 2500 mm) and subtract 4 centimeters of the gap for the guides - the resulting value will be the height of the door leaf:

Door H = 2500 – 40 = 2460 mm

After determining the height, the width is determined. It will depend on the type of handle being installed, of which there are two main types: open (opens from the side where the hook is located) and closed (the same everywhere). For this reason, the width will vary.

The width of the door leaf is also calculated depending on the number of door leaves - when their dimensions are determined, it is taken into account that they are mounted overlapping so that they can open freely in all directions. If the cabinet has 2 doors, there will be one overlap, out of three - two, four - here are the options: two or three overlaps. It is clear that the width depends on the number of door structures. For example, if there are 3 two doors in the closet, the sum of their widths should be approximately 2 centimeters greater than the size of the opening (due to overlap).

The visible length (L) + overlaps is the desired indicator, which must be divided by the required number of sashes:

L (open) = (2300+10*2)/2 = 1160 mm.
L (closed) = (2300+15*2)/2 = 1165 mm.

Calculation of components

For closed and open handles, measurements are taken individually:

The handle is the side frame of the door, with its help the door leaf opens.
L handle = H door
Track - top and bottom - the upper rail, thanks to which the canvas is fixed in a vertical position.
Track (top and bottom) = N opening
Frame – tightens the door at the top and bottom.
L top/bottom frame = L doors – 50
The insert is the external facade: mirror, glass.
H insert = H door – 60, L insert = L door – 40

As for the inserts: it should be remembered that the standard width of the sheet is 4 mm (glass or mirror) plus an auxiliary seal (sheets of plywood or chipboard).

If the insert is without glass, but simply uses a dense material (suitable dimensions 10-12 mm), you can do without a seal.

During installation you will also need the following parts:

Rollers (upper and lower, 4 pieces each);
Hex key screws (sold with rollers).
Brakes (4) F
Mirror seal (silicone);
The pile is dustproof;
Self-tapping screws (4.5*60) 8-10 pieces.

A very important note - the dimensions of the guides should be 2 cm less than the H of the opening to facilitate installation. If we are talking about cabinet furniture, then the length should be generous, because during installation it turns out that the lengths of the upper and lower rails are different.

Assembly and installation of sliding wardrobe doors

You need to assemble the structure on a flat table or on the floor, first leaning it against something (a wooden beam).

General assembly algorithm:

File the profile;
Tap the top frame (tap gently with a rubber mallet);
Stuff the bottom frame;
Level the horizons (insert protrusion 7 mm);
Installation of the handle (7 mm indentation);
Put on the handle and side handle;
Pull the frame;
Screw in the screw at the top;
Installation of rollers and seals;
Installation of mirror inserts.

Inserts with a coating (film) at the edges should be rounded; if they are at a right angle, the film may be damaged.

Installation algorithm:

We insert the sash into the installed upper guide mechanism.
The rollers are installed in the lower track.
The door is adjustable horizontally and vertically.
Install the remaining parts: from far to near.
If the facade is skewed: adjust using a hex key and screw the roller. In the direction of the clock - raise it, against the clock - lower it.

Sliding interior doors

Recently, double-leaf interior sliding structures have gained great popularity, the main advantage of which is saving space.

You can install them yourself; to do this you need to purchase:

Door leaf.
Sliding mechanism.
Pens.
Lock (if necessary).

This kit is already enough for installation. To make new interior doors look more attractive, you should think about replacing other parts:

Door frame (you will need a rail).
Platbands.
Bar for sliding system.

Installation begins with preparing the door leaf: first, a small slot is made in the center with a grinder (it serves as a door stop), rollers are screwed on all sides, a lock is installed, and handles are attached. Then you need to install the sliding mechanism in the doorway. Pay special attention to the length of the guide, adjust it to size if necessary, and calculate the correct installation height.

Thanks to the rollers, the blade can easily be installed in the guide.

A rubber stop, upper and lower stops are attached to the three-millimeter gap.

It is advisable to carry out the work after replacing the door frame: it is made of slats, reinforced with foam, and trims are installed. If the interior doors have a lock, then in place of one of the platbands a beam is placed where part of the locking mechanism will be located. The frame can also be decorated with stone, laminate, to match the design of the room, so that the interior doors look harmonious.

It is quite possible for a person with practical skills to assemble a wardrobe with their own hands. The main difficulty lies in the manufacture of sliding doors. To avoid mistakes, you must strictly adhere to the rules for calculating the size of canvases: take into account the height, width of the opening, the number and size of doors, type of profile and other fittings. In this article we will tell you how to correctly collect the initial data, what you will need for this, and you can independently calculate the exact parameters using our calculator.

Measuring the opening

The correct determination of the dimensions of door structures depends on the accuracy of the measurements. Measuring an opening consists of 2 main operations:

Measuring the height of the space between the extreme points of the internal surfaces of the top and bottom plates of the cabinet.
The width is determined by the same method between the outer side walls of the compartment.

Accuracy of measurements is the key to quality

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.

Influence of the number of sashes on calculations and location options Lп - opening width, Lс - leaf width

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

They purchase ready-made doors and install the wardrobe body based on their dimensions.
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.

Calculations

To begin, we need the following data:

opening height
width of the future cabinet
number of door leaves
number of overlaps
fleece seal thickness
frame profile width
thickness of both guides

Correct calculation of all the component parts will eliminate mismatches, distortions, and failures during the installation of the panels in the wardrobe.

Determining the height and width of the opening

Before starting measurements, you need to check the level of the horizon of the upper and lower plates, the verticals of the side rails and the rear wall of the cabinet and eliminate deviations if they are detected. Then proceed to determine the width and height of the opening:

Read also: Standard height of lower kitchen cabinets: ready-made and custom-made modules

Measure the distance from the inner surface of the bottom plate to the bottom point of the upper floor of the body.
Measure the distance between the inner surfaces of the outer side walls.
A control measurement of the length of the diagonals between the opposite points of mating adjacent surfaces from the inside of the cabinet is carried out - they must be equal to each other.
If there is a difference in lengths, this will mean a violation of the geometry of the wardrobe body. The distortion is eliminated with pads under the base of the cabinet.

The obtained values are the basic data necessary for calculating wardrobe doors.

Accounting for overlaps

Wardrobe doors move relative to each other along parallel tracks. When the opening is closed, the internal racks overlap by the width of the profile. These intersections are called overlaps. Their number is one less than the number of doors. For example, a three-leaf system has two overlaps, the width of which is taken into account when designing sliding systems.

Calculation method

To clearly understand all the nuances, let’s take as an example the specific dimensions of the opening. Let's say the basic input data is:

height H pr = 2400 mm;
width L pr = 2700 mm;
number of door leaves N = 3 pcs.;
buffer tape thickness B = 6 mm;
number of overlaps A = 2 pcs.;
frame profile width C = 20 mm;
thickness of both guides S = 40 mm.

The parameters of the upper and lower guides of the cabinet body must be taken into account in the calculation. The upper support bar in the section represents an inverted letter “W”.

Buffer tape can be of different widths. The minimum pile thickness is 6 mm, and the maximum value is 10 mm. This factor is taken into account when calculating sliding systems. In our case, the calculated thickness of the tape is 6 mm.

The profile of the handles determines the width of the vertical posts framing the door leaf. The aluminum racks are made with grooves for fixing the blade and have a bend on the outside for easy grip by hand. The thickness of the horizontal and vertical frame slats is the same and is 20 mm.

The calculations are made in the following order:

door height H in = H in – S = 2400 – 40 = 2360 mm;
width taking into account 2 overlaps L dv = (L r - AC - AB) / N = (2700 - 40 - 12)/3 = 2648/3 = 883

The size of each of the three canvases is 2360 x 883 mm.

If the number of doors is different, then calculations can be made using the formulas:
leaf height H in = H in – S;
width L dv = (L pr - AC – N bf B), where N bf is the number of buffer tapes;
filling height Hnp = H dv – 2C – 2D, where D is the depth of the groove in the frame;
width L np = L dv – 2C – 2D.

Calculation of infills

The filling parameters are determined by subtracting two values from the door dimensions - the width of the horizontal strips and vertical posts (handles), as well as two thicknesses of the buffer tape.

The size of the standard door frame filling (mirror, LSDP or MDF) will be:

height 2360 – 40 = 2320 mm;
width 883 – 40 – 12 = 831mm.

To the obtained indicators you need to add the depth of the grooves in the profile (3 mm) to install the filling. The final size of the canvas will be (2320 + 6) x (831 + 6) = 2326 x 837 mm.

When combining inserts, it is necessary to take into account the wall thickness of the aluminum I-profile T (2 mm), which is attached to the frame posts. Fragments of filling made from different materials (mirror, chipboard or MDF) are inserted into its grooves.
The height of the combined filling inserts Hvs (the width remains the same) is calculated as follows:
H sun = (H np - (N – 1)T)/N, where N is the number of inserts.
For example, the filling consists of 4 equal fragments with a frame opening height of 2320 mm, the thickness of 3 connecting profiles is 2 x 3 = 6 mm, then the height of each insert will be:
(2320 – 6)/4 = 578.5 mm.

Repair is a long process and it is difficult to keep everything under control. Selecting and purchasing furniture is a stage that directly brings you closer to a pleasant result of all work. But even calculating the exact dimensions of furniture and its parts can be confusing. To prevent this, it is worth knowing the correctness and sequence of actions.

Sliding wardrobes have long become an integral part of modern apartments due to their functionality and convenience.

Sliding wardrobes have been a part of our lives for a very long time. Their simplicity, durability, accessibility and functionality have captivated many. Determining measurements is a fairly understandable and everyday matter, but calculating the size of wardrobe doors makes you think.

The larger the compartment door, the heavier the door leaf, which makes it difficult to move.

The height of sliding compartment doors can be obtained using the formula

Structural elements that make up a lower support compartment door

To correctly measure the height of the opening, follow these tips.

Cover thickness.
Dimensions of the thickness of the lower guides with a roller design.
The gap between the lower guides and the canvas.
Calculate the required gap for installing the door (approximately 14 mm).

Doors for sliding wardrobes consist of a frame - vertical, upper, lower profile and filling (glass/mirror or chipboard)

The role of the top guide for compartment doors

Cross section of the top guide for sliding wardrobe doors

The main function of sliding wardrobe guides is their easy and accessible opening and closing. The basis of this system will be the rails along which the doors move. There are also many additional details.

Top guide - its role in keeping the door from falling out

The dimensions of the door guides depend entirely on the dimensions of the doors themselves. Basically, there is no need to buy them separately from the furniture, since they come included. But if you made the cabinet yourself, or the old part is out of order, then you need to measure it.

The purpose of the top rail is to secure the cabinet at the top. And also, using rollers, moving the doors.

Determining the width of wardrobe doors

We determine the height of the sliding wardrobe doors and calculate the width of the doors using the formulas

The accuracy of measuring the width of a compartment door depends on the formality already known to you. It is important to verify the measurement results, namely, do them 3 times and in different parts. This simple procedure can save you from misconceptions.

The specific dimensions of compartment doors depend on the option of moving the leaves and the features of the sliding system

A distinctive feature of this stage will be taking into account the number of door partitions. The following sequence must be followed.

+ overlap between doors. It hides the interior space.
+ certain addition to the side parts of the doors.

Calculation of compartment door leaves

Calculation of the size of the overlap of compartment doors from an asymmetric profile

In order for the doors to overlap and not interfere with each other, it is necessary that the rear guide be removed from the front

The sliding part of the cabinet is designed to be used in open and closed positions. A mandatory condition is that the profile of one of the valves covers the surface of the second.

Determining the size of the door overlap is simple: the width of the opening is divided in half (assuming the cabinet is even) and the size of the handle is added. Thanks to these simple calculations we determine the width of the overlap.

Overlap size of compartment doors made of asymmetrical profile

Provided that the profile is asymmetrical, then the width of the opening is measured separately for the top and bottom and each door.

Section of the profile of an asymmetrical handle

Also, to make calculations easier, some masters use a fairly simple rule. It sounds like this: the size of the overlap should be equal to the width of the door handle.

Conditions that may affect the overlap size of compartment doors:

fittings size;
handle dimensions;
number of doors;
the presence of a schlegel (a part that softens the impact when opening the doors).

Correct execution of calculations will ensure convenient use of furniture.

Drawer for wardrobe, top view

To determine the size of the boxes, you need to determine their location. You should also choose the dimensions of the future storage space at your own discretion. Then we turn this “air data” into numbers. Using a tape measure, we take measurements similar to the door.

Calculation of the height of drawer parts

The box itself consists of slats that have their own thickness. This detail may cause the box to not fit. Therefore, it is worth finding out the width of this material and taking it into account. In most cases, the width of the drawer is 5 mm larger than the guides.

A complete algorithm for calculating the size of a cabinet drawer

Subtract the thickness of the central partition and sides from the total width of the cabinet.
Subtract the width of the material from the resulting number and divide into sections.

Components of cabinet drawers

Thus, we found out the width of the shelves themselves.

To calculate the space for drawers, subtract approximately 35 mm from the width of the shelf. And this is the width of the box itself in the shelf. The need to take away from the need to open a drawer without catching the door.

How to calculate wardrobe doors without incomprehensible online diagrams and calculators?

The calculation of compartment doors for different systems may vary, so we will focus on the general approach for calculating compartment doors in order to understand the principle of their calculation.

Let's consider calculation of compartment doors using the example of the Raumplus aluminum system, the ancestor of all other systems, which, if they differ, are only slightly different. Analogues of Raumplus include the Polish Senator, Chinese Aristo, and Russian Versailles.

The first thing to start with when calculating compartment doors is to determine the size of the opening in which the compartment doors are supposed to be installed. When measuring, check the dimensions at several points.

We have received the size of the opening, we proceed to calculating the length of the upper and lower guides for the compartment doors and the dimensions of the compartment doors themselves.

Calculation of the height of compartment doors

If you look at the cross-section of the profile of the top rail for sliding wardrobe doors, then the height of the internal space of the top rail where the sliding doors will go is 45 mm, reducing the height of the doors relative to the opening by 40 mm allows you to bypass height differences of 10 mm or more. The upper guide will not allow the compartment door rollers to jump out.

Calculation of the width of compartment doors

When calculating the width of a compartment door, the width of the compartment door should be such that the doors overlap by the width of the handle.

Sometimes this scheme also takes into account the width of the bumper brush, but usually this is neglected. If you still decide to take this point into account when calculating the compartment door, then subtract two thicknesses of the fender brush from the width of the opening.

That is, if the brushes are 5 mm thick, then subtract 10 mm from the width of the opening and use the already obtained value as the width of the opening to calculate the compartment door.

Beautiful wardrobe with lighting and an additional side shelf

When buying a new home, moving, remodeling, or simply when you want to update the design of your apartment, we always think about what furniture to choose so that it is comfortable, beautiful and functional. Of course, when considering options, we also rely on the dimensions of the future sofa, table or shelf. Everyone wants the furniture in their apartment to take up as little space as possible, especially if the area of the room does not allow you to purchase exactly what you like visually.

Closet. built into the niche of the room

A closet for clothes, linen, and personal belongings is very necessary in any room. It is suitable for storing everything that is used daily or periodically, saving items from dust settling and contamination by household liquids. For many of us, when we hear the word wardrobe, the first thing that comes to mind is the image of a familiar design with mezzanines, glass doors and drawers. You can quickly buy such furniture in a store by simply telling the seller the dimensions, choosing the color, as well as the type of product. As practice shows, suitable products are not always sold.

A dressing room hidden behind sliding doors allows you to optimally use the space and hide everything from prying eyes

A new product has appeared on the furniture market relatively recently, which has won the love of customers, devoid of many of the disadvantages of a conventional cabinet equipped with hinged doors that block the exit, entrance or space when they are opened. A sliding wardrobe can be built into a niche, which is provided during the construction of many apartments and often causes confusion about how to use it without spoiling the integral image of the living space.

Mirrored wardrobe for the corridor

Such a cabinet can be installed in the bathroom, bedroom, living room, kitchen, hallway, visually increasing the space due to, for example, mirrored doors. Its huge advantage is the unlimited dimensions (length, width, depth and height). Below we will look at the rules for correct calculation of this type of cabinets.

Sliding wardrobe for the living room with a beautiful landscape on the doors

Having chosen a place for installation and sketched it by hand, we begin to calculate and draw the initial design of the structure. All objects located in close proximity or in contact with the structure are taken into account, distances and thickness of materials are measured, and wall unevenness is taken into account. A prerequisite for successful cabinet installation is measuring the corners. There must be one hundred percent confidence that they are straight (90%).

Sliding wardrobe with dimensions and description

A standard sliding wardrobe consists of a roof, sides, partitions, bottom, ceiling, plinth, doors, back wall and internal contents (shelves, modules with drawers, belt holders, pull-out baskets, hangers, shoe racks, etc.). The dimensions of all parts should be taken into account when preparing the product design.

Drawing of a built-in wardrobe in a niche

Calculating the dimensions of the cabinet

For the initial calculation, we need to determine L - the height of the opening and B - the width of the opening

The first stage of cabinet design is marking

Height. The basic rule to follow is not to rely only on the parameters of the walls. Why? Contact with the ceiling will not allow the wardrobe to move into the desired position. This is a rather massive structure, which is usually assembled horizontally and installed vertically. Therefore, the most important value for calculating the correct size is its diagonal, the length of which is usually approximately 10 cm less than the height of the back wall. Here it is better to use the formula √(a²-b²) = x. For example: 2700 (distance from floor to ceiling 2700 mm) x 27 = 72900 (a2); 50 (cabinet depth 50 mm) x 50 = 2500 (b2); 72900 – 2500 = 70,400. Taking the root (use an online calculator) of 70,400, we get 265.32. We round up to 265. In total, the height of our product is 2650 mm.
Depth. Here it is worth mentioning right away that it is better to make this parameter no smaller than 550 mm, and preferably 650 mm or more, since the standard length of the hanger rod is 450 mm, so your clothes, especially bulky down jackets and fur coats, should feel comfortable in such cramped spaces. conditions. It is worth clarifying that the depth is chosen completely different, based on your preferences and the dimensions of the room.
Width. Everything is much simpler here. We measure the internal dimensions of the opening, subtract 16 mm (chipboard thickness) from this size, and obtain the mounted values of the opening.

Calculating the size of cabinet doors

In this case, the main thing is to avoid mistakes made when installing a sliding wardrobe yourself.

The parameters of one leaf should not exceed 2800 x 1200 mm.
You should not make very narrow doors.
It is important to take into account the overlaps of the canvases.

Design of sliding doors for wardrobes

Width calculation. When determining the length of the canvas, you should subtract 40-45 mm from the height of the opening (the required distance for hanging). To the width of the opening we add the length of the overlap in millimeters and divide by the number of doors. For example, 1584 mm + 26 mm / 2 = 805 mm (width of one leaf).

Calculating the size of the boxes

Detailing drawers for a wardrobe

Drawers are a very important and practical filling of the closet. To determine the boundaries of the box, it is necessary to take into account the data of all its parts: the front, bottom, side, back wall and guide.

Facade. The size of the opening should be 4 mm greater than the width of the facade. The height is chosen arbitrarily. Be sure to leave a groove in the facade for attaching the handle.
Bottom. When determining the dimensions of the cabinet bottom, you need to decide whether it will be nailed or inserted into grooves. Using the latter method, it is important to take into account the thickness of the material and the depth of the groove.
Sidewalls. Their length is a multiple or slightly longer than the length of the guide. The height of the side walls and the back wall of the box is equal to or 40-50 mm less than the height of the facade.

The size of the box affects all parameters of the retractable element: its width, depth and height

Methodology for calculating materials and components

A table must be drawn up indicating a list of all the parts of the outer box and internal filling (fittings, fasteners, handles) indicating their sizes and quantities. There are several dozen or even hundreds of such parts, depending on the configuration of the cabinet. The thickness of the edge must be taken into account, and the name of the material for each part must be indicated. You can use this data later when calculating the cost of the cabinet.

An example of filling a three-door wardrobe with an ironing board and a vacuum cleaner

To cut chipboard, a list of parts with dimensions is enough, with which you contact the cutting shop, select the material there and order the production of blanks for your cabinet.

Diagram of a 3750 mm wide cabinet with detailed measurements

When calculating materials and components, one should not neglect gaps and indentations.

The height of the base can be up to 100 mm.
The gap on each side of the drawer front is from 1.5 mm.
The internal filling of the product should be approximately 10 cm less than the outer casing.

Cabinet cost calculation

Approximate calculation of the cost of a sliding wardrobe depending on the configuration

Having in hand a table with a list and quantity of all necessary parts and materials, in the last column we write the cost of each item, focusing on the price in the store. Here it is necessary to pay special attention to the cutting of parts in the chipboard sheet (its structure, cut width, overall dimensions, which should be taken 20 mm less than the required parameters).

An example of calculating the price of a sliding wardrobe in the CupeCalc v1.0 program, built on the basis of Microsoft Excel using VBA macros

Parts made from sheet metal and various inserts, such as mirrors, are calculated by square meters. For clarity, let’s take the bottom of the structure, made of chipboard. As a basis, we take the cost of a sheet per square meter, the required width and length of the bottom (chipboard: 1100 rubles / m²; bottom: 1.5 m x 2 m = 3 m² x 1100 rubles = 3300 rubles) Long materials, such as plinths, are considered per linear meter, and do not cause any particular difficulties in assessment. Handles, latches, fasteners are counted individually.
