How to properly measure interior doors. How to measure the opening for the installation of the front door, comply with the norms and not make a mistake? Dimensions of interior doors

In order for the new door to optimally match the existing opening, it is necessary to determine the parameters of the elements included in the door frame kit. At the same time, there are some nuances that affect the location of the doorway and the appearance.

Before buying a door, you need to make measurements of the doorway.

Before you properly measure, you need to stock up on the following:

• tape measure;
• paper for recording dimensions;
• pencil or ballpoint pen;
• chisel.

Work order

Work on measuring the opening usually begins with the removal of platbands. They can be removed by squeezing them out of the door frame with a chisel. If after that the boundaries of the doorway are not visible, then the wallpaper and plaster at the measurement points are removed with a chisel. The size of the opening may vary depending on the location of the measurement. Therefore, the width is measured in three places. Two measurements are made at a distance of approximately 20 cm from the top and bottom of the door and one in the middle. Vertical measurement is done in two places. At the same time, attention is paid to the presence of a threshold. If there is no threshold, then the size from the top surface of the floor is taken into account. If the wall is thicker than 10 cm, then it will be necessary to determine the size of the additional elements. With the help of these details, slopes are formed.

If the doorway is narrow, then perhaps you should consider widening it. This can come in handy when shipping larger furniture. The size of the door frame should provide a gap between this box and the wall along the entire perimeter of 3 - 4 cm, which is then filled construction foam. The size of the additional elements should be such that, in total with the thickness of the door frame, the thickness of the wall is obtained. At the same time, a processing allowance must remain on the additional element to ensure a snug fit of the casing to the wall. Be sure to determine the opening direction of the door in order to provide sufficient space for opening and correct installation door hinges.

Entrance doors according to the rules fire safety should open outward.

There are non-standard doors. For example - with an arched vault. How to measure parameters in this option? Each non-standard case requires individual approach. In all cases, preference should be given to doors with a finished frame. When measuring, it is necessary to determine the presence of various communications that affect the opening. At the measurement stage, all the design features of the doors and the wishes of the customer are recorded. Competent measurement will ensure the proper quality of door installation.

It is important to know how to measure the opening correctly in order to finally order a model that is ideal for your parameters. You can call a specialist at home or carry out the entire procedure yourself, the measurement process will not take much time.

Before installation new door it is important to measure the opening correctly

Required indicators

In order to correctly measure the door, you will need to determine a number of indicators. For the convenience of work, it is recommended to write out all the positions on a sheet of paper in advance and find them sequentially one after another in the same order.

So, in order to measure the entrance or interior door, it is necessary to determine the following indicators:

• width - the distance between the side elements;
• height - the distance from the floor to the top floor;
• depth - the thickness of the wall in the opening;
• slope - the presence of distortions;
• evenness - areas where the value of the indicators has certain deviations.

Required indicators for correct measurement doors

Door width

Measuring the door begins with determining its width. Doing it yourself will not be difficult. If it's about standard openings, often their width is 80 cm for interior and 90-100 cm for front door.

The easiest way is to independently measure the distance between the side supports at the bottom of the passage, the floor can serve as a guide. Nevertheless, to clarify the dimensions, it is necessary to carry out auxiliary measurements at least at two more points: from above and in the center. For work, only a tape measure is enough.

Correct measurement of the width of the door and doorway

opening height

The next indicator is . Approximately this value is 210 cm. In order to find out how many centimeters is the distance from the floor to the top of the opening, you will also need a tape measure. It is not always convenient to work independently in this case.

New doors are recommended to be installed in the opening after laying the flooring. This is especially true if you are planning to order an interior door. In this case, you do not have to calculate the thickness of the flooring or trim the elements door structure directly during installation.

You also need to measure the height at several points, the main reference point is the center. Measurements must be taken according to inside opening. All three values ​​may differ from each other, which will affect further measurements.

For more exact definition the height of the opening is measured in three places

additional characteristics

The width of the opening is different from the width of the door itself. It is measured in the same way. At the same time, please note that you need to order a box a few centimeters less, since technological gaps for installation are provided here. Also take into account that the width of the box will be larger than the canvas. There should be small gaps around the perimeter to ensure the free movement of the door.

The basic measurement of the entrance or interior door is completed by determining the thickness of the elements. For the entrance, this figure will be greater than for the interior door. In fact, this value depends on the thickness of the wall itself. The box must completely cover the opening. If the value is too high, the additional installation of extensions is provided.

Measurement of the width of the opening is carried out according to the same principle as doors.

opening evenness

It is also important to determine such parameters for future door, which will allow you to align the opening. This is important not only to facilitate the installation process, but also to improve the further functioning of the structure.

First of all, you need to check the vertical of the opening. For this, a level or a special plumb line is used. The rule of three points is also observed here: left, right, center. The next parameter is the diagonal. Using a tape measure, measure the distance inside the opening from the top corner on one side to the bottom in the opposite corner. Both indicators for each combination of sides must match, or at least not have serious deviations. If the values ​​are very different, this will be noticeable even at the stage of carrying out the basic measurements, since the diagonals depend on the height of the sidewalls and the width of the top and threshold.

The evenness of the opening is an important indicator when measuring the door.

The presence of serious distortions will affect the durability of the fasteners, their normal operation and may lead to a deterioration in the overall appearance passage.

Elimination of defects

To install the door as correctly as possible, without distortions, it is necessary to make a slight adjustment to the dimensions of the opening. If serious irregularities were identified, the best way out of the situation would be to plaster the opening and cut off the sagging.

If you want to bring out a flat wall or partition, you can immediately take care of removing the ideal opening by attaching it to the frame drywall sheets. In the future, it is required to superficially plaster the opening.

Carrying out a thorough measurement allows you to determine the ideal parameters for choosing a new door. This will facilitate the installation process and will positively affect many other aspects.

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. Standard Width door leaf- 60, 70, 80, 90 cm, box thickness - 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.

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 to order the canvas interior doors?

In the size of the door, the main characteristic is the width of the leaf. If width doorway 93 cm, which means that 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.

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. To correctly calculate the width of the required extension, you need to measure the wall thickness in the 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 more than 0.5 cm thick, 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.
