Before choosing, purchasing and installing interior door, it is necessary to correctly determine the width and height of the doorway, the thickness of the walls, calculate the dimensions of the leaf itself, take into account technological gaps. Compliance with the following rules will ensure trouble-free operation and long term door service:

• the width of the opening is measured cleanly between two vertical slopes; the height is taken equal to the distance between the plane of the upper slope and the level of the finished floor;
• when measuring the opening without first dismantling the old door, measurements are made similarly to the previous paragraph, but only after removing the platbands;
• in case of violation of the integrity of the slopes, a significant difference in height dimensions, the presence of an excessively wide or narrow opening, etc. contentious issues it is better not to take risks and contact a specialized organization; an experienced measurer will give reasonable recommendations and help resolve a non-standard situation.

When the dimensions of the opening are determined independently or with the participation of a professional, it is not at all difficult to calculate the appropriate door dimensions. To do this, take into account the following nuances:

• geometric dimensions door leaf in width should be reduced by the standard gap, which is 35-60 mm from the left and right side;
• the height of the door should be equal to the height of the opening minus 50-80 mm; the gap is left on the side of the upper slope, but at the same time, the level of the finished floor is taken into account.

In practice, it looks like this: with door leaf dimensions of 700x2000 mm, the width of the opening should be 770-820 mm, and the height should be 2050-2080 mm, in case double doors with leaf dimensions of 2x600x2000 mm - this is 1270-1320 mm wide and 2050-2080 mm opening height. Not recommended to go beyond established norm sizes, otherwise it is fraught with either deformation of the door, or a significant weakening of its fasteners.

As for the thickness of the wall, the measurement results have a direct impact on the size and number of extensions. Modern telescopic dobors complete with telescopic architraves and a box are very technologically advanced. Their width is adjustable and fixed in place. With a wall thickness of 80 mm, extensions are not used.

How to measure front door

To Entrance door fully met its purpose, was functional and served reliable protection house, before installing it, it is necessary to correctly measure the opening, determine the dimensions door block, provide the required gap size. Errors and miscalculations will cause operational difficulties or general unsuitability. installed door. The basic rules for measuring work are:

• measurement of the height and width of the opening "in the clear": from the left slope to the right, from the upper slope to the bottom of the opening;
• when replacing an existing door, the dimensions of the opening are determined after preliminary dismantling of the platbands and providing access to the edge of the wall;
• in case of unsatisfactory condition of the slopes: painting the masonry of the walls, violating its verticality, it is more correct to turn to the services of specialists; professional approach will avoid possible mistakes and unnecessary expenses.

After measuring the opening, determine the required size of the front door. In this case, the dimensions of the door unit should differ by the size of the mounting gap between the wall and the frame. The distance between adjacent surfaces is set as follows:

• across the width of the opening: from 10 to 50 mm on each side of the vertical slopes;
• along the length of the opening: 10-50 mm between the upper slope and the crossbar of the door block, leaving a small distance from the side of the threshold.

For example, with dimensions of a door block of 860x2050 mm, its width can be in the range of 880-960 mm, and its height can be 2070-2100 mm. With dimensions of 980x2050 mm, these are 1000x1080 mm and 2070x2100 mm, respectively. Everything is extremely simple and accessible for self-calculation.

Entrance door opening size table

The presence of a gap is necessary not only from the point of view of installation, but also in the event of thermal deformations of the front door. Maintaining the required distance has special meaning when installing wooden blocks, however, its value should not exceed the maximum allowable sizes. An excessively large gap will cause a significant deterioration in the heat-insulating ability and fastening strength of the entire structure. That is why, with a significant exaggeration of the width of the opening, it is recommended to partially fill it and thereby reduce the initial dimensions. If the reverse situation occurs and the existing width is insufficient, then the opening is further expanded.

If you decide to take the measurement yourself, read the information provided to do it correctly.

Measurement of an empty opening

Simplest measurement option when measuring a new empty doorway or old door completely dismantled. In this case, you need to do:

1. Width measurement doorway . Performed at the top and lower part opening, since the opening can be made not in level and have a constriction from one side. In this case, it takes the smallest of the obtained values ​​\u200b\u200b- this will be the width of the opening. The standard width of the door leaf is 60, 70, 80, 90 cm, the thickness of the box is 2-4 cm, so optimal width opening should be: 65-68 cm, 75-78 cm, 85-88 cm, 95-98s m.

2. Height measurement doorway . Performed similarly measurement by width: on both sides and the minimum of the measured values ​​\u200b\u200bis taken. The standard height of the door leaf, manufactured by Belarusian and Russian manufacturers, 200 cm, frame thickness from 2 to 4 cm, so to install a door without a threshold, optimal height opening should be 204 - 208 cm.

3. wall thickness measurement. The door frame is usually made 7 cm wide, if the width of the wall is greater than this value, then the remaining part is usually closed with an additional plank (standard sizes 10, 15, 20 cm). Please note that if the wall narrows, it is necessary to take the maximum measured value so that the width of the extension is exactly enough. If the wall thickness exceeds 26 cm, then, as a rule, dobors are not installed, but a box is installed and slopes are made.

Measuring the opening with the old door installed

Measuring an opening in which an old door is still installed is a little more difficult than an empty one. The principle of performing measurements is exactly the same as in the first case, but there are nuances:

1. To perform the measurement, it is necessary, if possible, to dismantle the old architraves on one side and measure the height and width of the doorway, as indicated above.

2. The thickness of the wall is measured from platband to platband.

These dimensions are the information that makes it possible to correctly place an order and eliminate problems during installation.

What do you do before you buy new clothes? Determine your size. Doors are an outfit for your apartment, and here it is very important to know the exact dimensions so as not to make a mistake when buying. There is a fairly simple general system to help you get the right interior doors in Tula .

Opening dimensions

Before you start measuring, make sure that nothing will interfere with you. There should be nothing superfluous in the opening, remove the old box, trim, bare walls should remain. Typically, the standard width of openings in apartments is approximately 0.9 meters, and a height of 2.1. It happens, of course, and more, up to 2.3, so check the measurement to avoid mistakes. Then we need to take into account the fact that before the door leaf is installed, the box and insulation will take their rightful place in front of it. Their total thickness will take approximately 2.5 cm. But we have two slopes, which means that we multiply this figure by two, subtract the resulting amount from the width of the opening. For example, if we have an opening width of 0.86 meters, then the following formula goes 0.86-0.025 * 2 = 0.81 meters. So we got the size of the door leaf. In exactly the same way, we calculate the height, with the only difference, there is no need to multiply the thickness of the box by two. It has three sides, and the lower element is missing there. This formula is equally good for measuring both wooden and metal doors.

Wall thickness

In order to measure the thickness of the walls, it is best to use a caliper, it will help you accurately, quickly and conveniently calculate the dimensions we need. But if your house doesn't have one useful tool, do not be upset and do not rush to the store. It is quite possible to replace it, for this we use a cunning system. Place rulers on both sides of the doorway, measure the distance between the ends protruding from the opening. If your apartment is not located in a new building, but, for example, in a Stalinist building, then the thickness of the wall there can be much greater than in other houses. For such cases, you will need to install additional slopes.

If you decide to change everything at the same time interior doors and buy the same models in one place, you can get a "pleasant" surprise. When the boxes that fit perfectly into the living rooms are absolutely not suitable for the kitchen or bathroom. And most often a small threshold is to blame for this, it was he who stole such necessary centimeters of your house. If you forget about it, you will have to shorten the doors. This is extra hassle and serious damage to the aesthetic side. And metal or plastic doors generally not subject to such manipulations.

Before you start measuring, make sure that the walls and ceiling are completely finished. It would seem that the plaster that it can change, or too flooring. But believe that sometimes these millimeters can play a decisive and fatal role in your repair. Don't buy doors in Tula until major repairs are completed.

When buying a new interior door, it is important not only to choose the design and color of the structure, but also to correctly determine the dimensions of the canvases for each room. To do this, you must first make accurate measurements. doorways, and after that, based on this information, calculate the dimensions of each door block.

Standard and non-standard doorways

In typical high-rise buildings doorways usually have a standardized width depending on the room:

• bathrooms and bathrooms - 63 ... 76 cm;
• kitchen - 77 ... 87 cm;
• living rooms - 88 ... 110 cm;
• opening for the front door to the apartment - 90 ... 110 cm.

The height of the opening in kitchens and rooms varies from 204 cm to 210 cm, and in bathrooms and toilets there are often passages 194-203 cm high, which requires the installation of lower canvases or changes in the dimensions of the installation site.

Passages are not standard width and heights are usually found in old buildings and private cottages. Also, often as a result of redevelopment, even in standard apartments, instead of standard openings equip wider or higher aisles.

You can take measurements of doorways by inviting a professional measurer. But if you decide to measure yourself, then you must first learn the rules for performing this operation - how to correctly measure the width of the opening, how to correctly measure the height of the opening and how to measure the thickness of the wall.

How to correctly measure the width of the opening?

The width of the doorway is measured at three points - top, middle and bottom. From the values ​​obtained, the minimum result is selected, and it will be the width of a particular doorway.

In typical apartments, the following width standards are usually adhered to door structures by setting:

• in the kitchen - canvases 70 cm;
• in the bathroom and toilet - products 60 or 55 cm;
• in rooms - models 80 cm;
• as a second entrance door - 90 cm options.

Majority major manufacturers produce door leafs adapted to the dimensions of typical passages. The width of the canvases is usually equal to 600 mm, 700 mm, 800 mm, 900 mm. Some trademarks you can also find models with a width of 550 mm and 400 mm, but their choice is small. Such a variety makes it easy to choose a canvas for a typical room.

If you have old doors installed and you are satisfied with their width, then you can simply measure the parameters - let them correspond to the dimensions of the new door leaf.

How to correctly measure the height of the opening?

The dimensions of the opening in height must also be measured at three points - along the side slopes and in the middle. From the obtained values ​​​​the smallest is chosen, for this parameter it is necessary to select doors.

The standard height of the door panels is 2 meters, they fit into the mounting place with a height of 204 to 210 cm. With a higher passage height, the width of the standard trim may not be enough to mask the junction of the door frame and the wall. In this case for decorative frame door construction use wider platbands or install a portal with a capital.

AT model range some brands you can find models with a height of 1.9 meters. They are installed in bathrooms and toilets. Such canvases are suitable for aisles with a height of 203 cm or less.

IMPORTANT!

Even if you are sure that the repair in your house is done perfectly, you should still measure the doorway at three points in height and width. Otherwise, you run the risk that the finished door unit will be wider or higher than the installation site, and you will have to bear unplanned costs.

How to measure wall thickness?

To determine the wall thickness, measurements are taken at three points and the largest of these values ​​\u200b\u200bis chosen. The standard for doorway wall thickness is 6 to 8 cm, which is what most manufacturers of interior doors are guided by.

If the wall thickness is greater than the width of the box beam, it is necessary to install door extensions. These are strips of various widths, with the help of which door slopes are formed. They have the same texture and color as the entire door structure.

Door extensions not only give the opening an aesthetic appearance, but also protect the slopes from scratches and abrasion. Therefore, do not save on their installation.

When to take measurements?

An accurate measurement of the dimensions of the doorway is carried out after finishing the walls and laying the decorative flooring. Otherwise, there is a risk that the selected doors cannot be installed due to the fact that the opening is smaller than the dimensions of the door block.

But it is necessary to pre-measure the doorway even before performing a rough finish. This will allow you to choose the size of the opening in accordance with the line of standard canvases. And then you don’t have to overpay for interior doors standard sizes.

It is not difficult to reduce the size of the passage; brick, drywall or wood are usually used for this. The expansion of the installation site can affect the strength of the wall, this operation must be carried out with caution, strictly observing the established building codes.

Why are measurement errors dangerous?

Professional measurements are a guarantee that the doors you have chosen can be installed quickly, without problems and without additional financial costs. After all, it is far from always possible to increase the size of the installation site, especially when it comes to bearing wall. And if it's already done finishing walls, then to narrow the passage you will have to spend a lot of effort and additional money.

If you are not sure about your measurements or do not want to take risks, then it is best to purchase doors with a turnkey installation. In this case, the seller is responsible for the correct measurements, so you can be sure that each doorway will correspond to the dimensions of the leaf, and if there are errors, all replacements will be made at the expense of the installer. You can order a turnkey installation service in the online store of the Porta Prima factory or in sales outlets.

Swing door dimensions

Determining the dimensions of a swing-type door is carried out taking into account the height and width of the leaf, the thickness of the door frame, the presence or absence of a threshold.

The passage parameters for mounting a swing door block are calculated according to the following rules:

• opening width = web width + box thickness x 2 + mounting gap 2 cm x 2 + technological gap 3-5 mm;
• opening height when mounting doors without a threshold = leaf height + frame thickness + mounting gap 2 cm x 2 + technological gap 3-5 mm;
• passage height when installed with a threshold = web height + box thickness x 2 + mounting gap 2 cm x 2 + technological gap 3-5 mm.

Using these simple formulas, you can easily calculate the dimensions of an interior door for each room in an apartment, house or office.

Don't forget about extras. Finishing strips are produced different widths, they can be joined together and cut along, which allows you to pick up decoration for walls of any thickness. With their help, you can also mask the vertical deviation of the slope; for this, the bar is cut off in the form of a wedge.

Sliding door dimensions

Sliding doors today are increasingly replacing traditional hinged designs.

Dimensions sliding systems depend on the type of mechanism used:

• sashes move parallel to the wall;
• the canvas goes inside the wall into the cassette;
• panels overlap when opened.

For example, for sliding door structures, the leaf should be 5-7 cm wider than the opening. This is due to the fact that such doors, in fact, perform the function of a screen and should block the passage from the side. Therefore, the leaves can be significantly wider, but not narrower than the width of the passage.

If a sliding door-pencil case is installed, its width is selected so that the canvas protrudes slightly from the wall. This allows you to conveniently close the doors.

For wide openings, designs of two or more wings are used, which are selected from standard-width canvases. In this way, it is possible to block passages of almost any size.

Non-standard doorways - solutions

If in your apartment or house custom sizes openings, then best solution there will be a narrowing or widening of the passages up to standard dimensions. This will allow you to install standard interior doors instead of ordering custom-sized canvases.

The advantages of installing door blocks of standard sizes include:

• fast installation time - canvases are available in stock;
• much lower price than models of atypical sizes;
• a wide range of designs and colors.

If the selected canvas does not fit in the height of the doorway, you can trim it. Doing this on your own is undesirable, since you need to use professional tool. It is best to contact a company that provides such services.

In some cases, it is not possible to change the dimensions of the passage for technical or financial reasons. Then you have to order the production non-standard doors. They cost 30-40% more than mass-produced products, and their production usually takes several weeks.

You will need to arm yourself with a tape measure, a sheet of paper, a pencil or a pen.

This is the simplest example of measuring doors. You will need to arm yourself with a tape measure, a sheet of paper, a pencil or a pen. The main values ​​necessary for the future order of doors are: door height, door width, wall thickness, side opening of the door.

* a rare case when a canvas is required higher or lower than the standard - 2 meters high

What width should I order for interior doors?

In the size of the door, the main characteristic is the width of the leaf. If the width of the doorway is 93 cm, then a door leaf 80 cm wide will fit into this opening.

For a door leaf with a width of 70 cm, the opening will be too wide, and for a door leaf 90 cm wide, the opening will be narrow, since the thickness of the box on both sides of the leaf, which is 2-3 cm in the groove of the box under the leaf, must also be taken into account . Of course, the ideal opening for a door with a width of 80 cm will be between 85 - 88 cm.

Table depending on the size of the interior door leaf on the width of the doorway

If the width of the doorway is... ...then the width of the leaf will be equal to

670 - 700 mm - 60 cm.

770 - 800 mm - 70 cm.

870 - 900 mm - 80 cm.

970 - 1000 mm - 90 cm.

Thus, it turns out that the canvas should be at least 7 cm narrower than the doorway. But you need to understand that a box thickness of 3 cm is a minimum, and mostly for laminated simple doors. Minus the porch in the box, such doors may be enough for 6 cm from the opening. That is, if 3 cm of the width of the leaf remains, then the door assembly can be squeezed in. But this will not work with veneered doors or with a telescopic box. They have more thickness. Yes, and for the foam, too, you need a place.

Dimensions of a simple laminated box.

Do you need extensions and what width?

An additional element is a bar for expanding the beam of the box. It serves to close the section of the wall not covered by the box bar. In order to correctly calculate the width of the required extension, you need to measure the thickness of the wall in doorway and subtract the width of the box beam, this will be required size dobor. Typically, the width of a typical interior door frame is 7 cm. If the wall thickness is more than 7 cm, then extensions are needed. An exception may be if you have "L" shaped platbands.

When buying doors, you need to consider the most wide size the thickness of the wall of the opening where the door is planned to be installed. Example: at the bottom the wall thickness is 11 cm, in the middle - 11.5 cm, at the top - 12 cm. This means that the width of the door frame (door beam + additional plank) should be 12 cm. Otherwise, if the box is less in width than the thickness of the wall , then the platband will not lie tightly on the box and the wall.

When installing a door in an opening with a wall thickness of 11 cm (in the middle); 12 cm (from above), a gap may form between the wall and the casing in the intervals of a smaller wall thickness (where the wall thickness is 11.5 cm). At this shortcoming recommended to use gypsum mortar, or alibaster (sold in hardware stores in small bags) to cover the gap between the casing and the wall. Or another option: level the wall with mortar, so that the thickness of the wall is everywhere along the contour of the opening.

The width of the extension must be equal to or greater than the part of the wall to be covered. Those. if the wall is 12 cm wide and the box is 8 cm wide, then you will need an extension at least 4 cm wide. But in stores, as a rule, they sell extensions at least 10 cm wide. In our case, then you can buy 1.5 sticks and cut them in half.

What height to order the interior door leaf?

The height of the opening must be measured along the side slope on both sides. The size standard door, which can be bought in our online store, is 200 cm in height. If the opening in height from the floor to the upper partition is more than 210 cm, then the platband (which is attached to the upper box) will not be able to close the opening, resulting in a gap between the platband and the wall.

In this case, it will be necessary to reduce the opening in height or install wide platbands. If the opening is less than 203 cm in height, then the door with door frame the assembly will not be able to "squeeze" into an opening of this size. Then 2 options are offered: 1. trim the door, which can lead to a weakening of the strength of the door trim during daily use; 2. cutting the wall to expand the opening, which is much more expensive than the first option, but the door will not be subject to "non-production" changes.

How to determine the door opening direction?

To correctly determine the side of the door opening, it is necessary to stand facing the door in such a way that the door opens towards itself. If you open the door towards yourself and the hinges are on the right side of the opening is right, if when you open the door on yourself the hinges are from the left, then the side of the opening is left.

Notes

If you are renovating, doors are best installed last. First we make the floor, then the ceiling, then the walls, and lastly the doors. But if for some reason the doors need to be installed earlier, then the following should be considered:

When measuring doorways and openings, you need to pay attention to the floor and how it will be after repair. So, if in the plans of the owners it is planned to use flooring with a thickness of more than 0.5 cm, this value will need to be subtracted from the height of the openings.

If you have a difficult case or you can't figure it out, Then Call a Qualified Technician

on our website in the "Call the measurer" section.

There are a great many different subtleties and nuances when installing doors. Only a professional will be able to distinguish a doorway from a running one. Determine if doors need so-called extensions and which ones. Do technical calculations gaps between the door frame and the wall, including those through which various wires. And it also fits in there in which direction the front door will open (to the right or to the left), internal or outside(it all depends on how it will be located on landing). All this and more, a special plan of "measurements" is introduced, which is then transferred to the master installers.

Collaborating with professionals is a guarantee High Quality, saving time and effort, and most importantly - nerves.
