Sizes of metal doors: what's important to know

Standard is an advantage when it comes to door dimensions. Figuratively speaking, the size of the doors in the framework of the standard means that when choosing a door of a standard size, you do not have to ask yourself how to hang other hinges or knock out a larger door opening (or how to narrow the opening that exists).

When it comes to the front door, you see, it is better to experiment with the materials of the door leaf, texture, color, exclusive decorative elements or with the use of forging, but not with the size.

Otherwise, the door installation of inexpensive and fast can turn into a protracted and unpleasant work, especially when you install the doors without the help of experts (see Installing metal doors with your own hands: tips from practitioners).

Door dimensions

It should be immediately noted that the concept of the standard size of doors includes two standards at once: the size of the door leaf and the size of the door opening.

Standard sizes of doors and door openings of the consignment notes:

Standard sizes - recessed metal doors and door openings:

Unfortunately, the dimension of the door openings, and hence the size of the metal door, in practice does not always have a clear match with the guests (see Gost - metal doors). It should be noted that imported door sizes have a complete inconsistency with Russian standards.

General information

So:

• Most of the door openings today in new buildings (П44 М, П44, П3 М) have dimensions within 740–760 millimeters in width by 1.950–1.980 millimeters in height.
• In the houses of brick series are usually in the range of 880–920 millimeters by 2,050–2,100 millimeters.
• In old-style houses, for single-door doors, the dimensions of the openings can range from 830 to 960 millimeters in width and from 2,040 to 2,600 millimeters in height.
• In the nine-story houses of the seventies, quite often there are openings of 1.280 by 2.550 millimeters.

In general, it is a fact that the fact that door openings in houses from standard series have a greater variety of types of openings (expandable, with no niches at the entrance, narrowing) and overall dimensions is a fact. Therefore, the size of the metal door can vary even within the riser or the entrance of one house.

Regulatory Sizes

According to clause 6.9. SniP 210197 entrance door - emergency exit. And in accordance with paragraph 6.16. the height of the emergency exit cannot be less than 1.9 meters, the width must be not less than:

• than 1.2 meters - in the case of premises F.1.1. class when the total number to be evacuated is more than fifteen people; if it is a question of premises and buildings of other classes of fire functional danger, with the exception of F.1.3. class, then the total number to be evacuated more than sixty people.

Door dimensions металлических наружных на лестничных клетках и двери в вестибюли из лестничных клеток должны иметь ширину не менее чем расчетная, или ширину лестничного марша, которая установлена в 6.29. В любой ситуации ширина выхода для эвакуации обязана быть такого размера, чтобы учитывая геометрию пути эвакуации, через дверь или проем двери можно было, не встречая препятствий пронести носилки с находящимися на них людьми.

In a broad sense, the size of a metal door is determined by the corresponding guests, but their standards do not apply to special purpose doors and doors of unique objects. The required dimensions of the doors are dependent on the door opening, where they will be installed. Therefore, below are the reference tables of the typical dimensions of door openings.
