Avoiding crampedness: what should be the width of the door

Wanting to bring a bit of originality into the room, they rely heavily on the door. She is required to suit the owner not only in style, material of manufacture and opening mechanism, but also in width.

Standard door width according to GOST

For the dimensions of the door and the opening for it, standards have been developed that are clearly spelled out in GOST. In this case, the width depends on the height and model of the door leaf.

Table: parameters of the door leaf

Height (cm)	Width (cm)
	Single-leaf model					For a double-leaf model
190	55	60	-	-	-	-	-	-
200	-	60	70	80	90	120 (60 * 2)	140 (60 + 80)	150 (60 + 90)

The dimensions of the door determine the size of the opening. As a rule, the difference between the width of the door leaf and the width of the passage in the wall is between 6 and 15 cm.

Height (cm)	Width (cm)
194-203	63-65	66-76	-	-	-	-	-	-
201–205	-	66-76	77-87	88-97	98-110	128-130	148-150	158-160

Correct measurement of door width and opening

The width of the door leaf is selected based on the dimensions of the passage in the wall.

In measuring the width of the doorway, errors should not occur if:

• dismantle the old door block in advance and remove the remnants of the plaster so that the passage acquires clear boundaries;

• determine the width of the opening in three areas (bottom, top and middle), keeping the measuring tape strictly horizontal;

  

  The width of the opening is measured in three places, and when choosing the width of the door, the smallest result is taken into account

• stop at the smallest received width.

And to make sure that this passage in the wall is suitable for installing a door, the formula W _dv + 2 * T _k + M _z * 2 + Z _p + Z _z will help, where W _d is the width of the door, T _k is the thickness of the box, M _z is the mounting gap, Z _p is the gap for the hinges, and Z _z is the gap for the lock.

If we consider the optimal width of the passage in the wall according to this formula, it turns out that a standard door 80 cm wide with a box 3 cm thick, an installation gap of 1 cm, a clearance for hinges of 2 mm and a clearance for a lock of 4 mm needs an opening of size 88, 6 cm (80 + 2 * 3 + 1 * 2 +0.2 + 0.4 = 88.6 cm).

The width of the doorway includes the width of the door leaf, door frame and mounting gaps

Actions in case of errors in width measurement

When the doorway turned out to be slightly narrower than the measurements with a tape measure, the way out would be to increase the passage with a grinder, an electric saw or a puncher. It all depends on the material from which the walls are made.

Some passages cannot be altered at all due to the special layout of the premises. Therefore, the only option may be to order a custom size door.

It is not uncommon for the passage in the wall to be too large for a traditional door. The issue is solved by narrowing the doorway by inserting an additional section of material (for example, brick or board).

To make the opening of the brick wall narrower, an additional line of material is inserted into it

Dependence of the door width on the room

To get a comfortable and functional door, you need to pay attention to which room and who exactly it leads to.

Table: the influence of the type of room on the dimensions of the opening under the door

Door type	Room type	Doorway width (mm)	Doorway height (mm)
Single leaf interior doors	Kitchen	700	2000
	Bathroom / toilet	550-600	1900-2000
	Bedroom / children's room	800	2000
	Wheelchair disabled room	700-900	2000-2300
	Steam room	from 600	from 160
Interior double doors	Living room	1200 (600 + 600 or 400 + 800)	2000
Entrance doors	Home for the elderly and people with wheelchairs Kindergarten Medical institution	From 1200	From 1900
Entrance doors and separate emergency exit	Apartment house	From 800	From 1900
Entrance doors	Bath	700-1100	2000-2300

The width and other dimensions of the door leaf and opening are regulated by state standards. And how much the door fits a particular passage in the wall depends on its dimensions.
