How to properly measure the doorway of an interior door. How to independently correctly determine the width and height of swing and sliding doors? How to measure the opening and entrance metal door for 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 installing a 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. When it comes to 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 floor covering. 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 floor covering or cut the elements of the door structure directly during the installation process.

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 input or interior door 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.

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 size 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 of non-standard width and height are usually found in old buildings and private cottages. Also, often as a result of redevelopment, even in standard apartments, instead of standard openings, wider or higher aisles are equipped.

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 standards for the width of door structures are usually followed, 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 installation 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 joint door frame and walls. 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 whole 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 will not have to overpay for interior doors of non-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 your apartment or house does not standard 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.

To new door optimally matched 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.

What will be the door - hinged, compartment or sliding? In which direction will it open - to the right or to the left? And also what kind of fittings will be - the color of the hinges, the shape of the handle, what kind of lock will be - magnetic, with a latch, will there be a turntable and a key. All of these issues, along with color, material and finish, must be addressed prior to ordering. The purpose of the measurement is to clearly determine which components of what size you need to purchase to install the door.

Measurement of the doorway must be made after removing the box and platbands from old door if they were. If the repair is the first, it is desirable after laying the floor in order to know exactly the height of the opening.

Measuring the width of the doorway

Width is measured at three points - top, bottom and middle, choosing smallest value. The width of the doorway should be 8-10 centimeters larger than the door leaf for installation and adjustment - walls are rarely perfectly even, so mounting foam is used to adjust the door frame.

Measuring the height of the doorway

The height of the opening is also measured at three points, choosing the smallest value. The height of the doorway should be about 208 centimeters, taking into account the finished floor: two meters for the door leaf, a few centimeters for installing and adjusting the box, and 1 centimeter for the gap between door leaf and floor.

Measuring the depth of the doorway

The width of the wall already needs to be measured in six places: top, bottom and in the middle on one side and the same on the other. And here it is worth taking not the least, but highest value- if you have to buy an extension, it is better to take it with a margin, you can cut it off. The width of a standard door frame is 7 centimeters, that is, if the width of the wall is 17 centimeters, you need to take one 10 cm extension.

thresholds

Thresholds are usually placed in bathrooms and between rooms in which the floor level does not match. In other cases, they try to make them to a minimum in order to be able not to stumble about them.

Thus, as a result we get:

• The door leaf has standard height 2 meters, and the width, depending on the doorway, can be 60, 70, 80 or 90 centimeters. Less often 40 and 55 centimeters. Non-standard sizes significantly increase the cost of the door and lengthen the production time by almost two times.
• The door frame is taken in pieces, left, right and half on top - a total of 2.5 pcs. If the door has a threshold - you need to take 3 pcs.
• Dobors have standard width 10 cm and sawn in place when installing the door to required size. Therefore, if it is necessary to increase the door frame, for example, by 4 cm, two extensions are taken - one is sawn in half, on both sides of the door, and a quarter of the second is placed on top.
• The platband, or flashing, is taken in the same way, 2.5 sticks on one side and the same amount on the other, a total of 5 pieces.

Some manufacturers provide boxes, extensions and trims not in pieces, but in sets, and you should specify how many pieces the set contains.

In any case, each company provides the services of a measurer. After all, no matter how correctly the customer measures himself, for example, he may not have a level or an old centimeter tape has stretched. So the responsibility for the error is usually taken by the door installation company.

Before ordering an interior door, it is required to determine the dimensions (height and width) of the door leaf and the need to use extensions. For the correct measurement of parameters, you need to use a tape measure.

The width and height of the doorway must be determined in three places - below, in the middle and above, choosing the smallest value of the three. In addition to these indicators, it is also required to know the thickness of the wall, according to this value, extensions are selected.

Measuring the opening for the installation of interior doors

Using a tape measure, the width, height and thickness of the walls into which the door structure will be installed are determined. Any changes during the installation of the product must be taken into account. For example, leaving room for styling facing tiles or floor covering. If the wall thickness is more than 7 cm, an additional element must be ordered. It is sawn and adjusted to size directly during the installation of the canvas. Dobors are made in different widths, when taking measurements, you need to keep in mind that the products are included in the box by 1 cm (Telescopic molding system).

Web Width Determination

Standard canvases are produced with a width of 60 to 90 cm and a height of 200 cm. To accurately place the door inside the opening, it is necessary to leave an additional margin of 7–10 cm. Here is a small selection of indicators of the dependence of the parameters of the leaf on the width of the opening:

Add-on options

Products are a plank for masking a section of the wall visible in the opening. To correctly calculate the width of the element, you need to measure the thickness of the wall and subtract the thickness of the box beam. The standard thickness of the door frame is 7 cm, with thicker walls it is necessary to order extensions.

The width of the products must match the section of the wall to be closed, or be greater than it. For example, if the wall is 15 cm and the box is 7 cm, you should purchase an additional 9 cm.

How to determine the height of the canvas?

This parameter is determined by the side slope on both sides. Standard products have a height of 200 cm. With a higher opening, if the size is from the floor to top wall more than 210 cm, after installation, a gap is formed that will need to be closed. There are two ways to solve the problem - to lay free space, building up a wall, or order a door custom size. Sometimes the height of the opening can be less than 203 cm, then the door will not enter the existing space. The problem is also solved by two methods - a door of a non-standard size (190 cm) is ordered, a wall is cut to increase the size of the opening.

When conducting repair work doors are installed at the final stage, after finishing the floor, ceiling and walls. If you need to complete the installation earlier, then when measuring, take into account the thickness of the floor covering after its installation (subtract this figure from the height of the opening).
