A door in the interior connects the individual rooms with each other. With clever planning, the costs for the doors can be massively reduced. The prerequisite for this is to use only standardized door dimensions. Here is an overview of the usual dimensions of doors and what this means for the planning.

Avoid bad surprises

The nurses were amazed by the mid-1980s, when they wanted to move into their brand-new hospital in Aachen. Sometimes the doors were too narrow for the beds. A bad planning like this happened quickly. In a house, this can be a very expensive overhead. But if the openings are not only large enough for the furniture, but also meet the standard dimensions, the builder can save a lot of money. Instead of expensive one-offs, factory-made doors can be used. These products are mass-produced and are always much cheaper than handcrafted solutions. The industry manufactures doors in a sufficiently large variety, so that the right door can be found for all situations on the shell.

Basic elements of doors

To properly grasp a door, you look at it from the outside. If the door swings when opening, you stand right. If the door is hinged on the right, it is called DIN-right. If it has the hinges on the left side, it is a DIN left door. Doors are also divided into single-leaf and double-leaf doors. Single-leaf doors are standard, especially as a normal room door. Two-leaf doors are passages that can be enlarged if necessary. In the normal family home, this component is occasionally found in living rooms. This makes it easier to transport and route bulky items such as sofa covers, pianos or wall units.

The average growth of Germans has increased in the last thirty years, so a new door standard has been developed. Doors are only offered in two heights: 2020 mm and 2145 mm. The shorter doors are rarely used in new buildings. They serve primarily as a replacement for doors from older buildings after 1950.

Components of a door

Lining: the inner lining of the masonry
Folding clothing: the lining permanently attached to the lining, always on the door side
Decorative clothing: the detachable lining with the lining, always on the doorless side
Door hinge: the hinges of the door
Door leaf: the door leaf
Striking plate: the snap-in unit on the folding clothing or the door lining
Handle set: the lock and pawl carrier
Threshold: a floor-mounted board in the doorway

The combination of folded clothing, decorative clothing and inner lining is also called "door frame".

Door leaves are divided into "rebated" and "unfolded". Folded doors have a circumferential edge, with which they rest on the door frame. Unfolded doors are flush with the frame. For normal, lockable doors usually rebated versions are selected. Swing doors are basically unfolded or dull.

Shell dimensions for door openings

The shell dimensions depend on the width and height of the selected door. All in all, the following values ​​can be used: width of the door element plus 8 cm, height of the door element plus 4 cm. So is circulating 4 cm of air, which is perfectly sufficient for a frame.

The standard height for doors described in the previous chapter gives the following values ​​for the wall opening:

Wall opening height according to DIN 18100

  • small / old: 2010 mm, at least 2000 mm, at most 2020 mm
  • large / new: 2135 millimeters, at least 2125 millimeters, at most 2145 millimeters

Wall opening width according to DIN 18100

Standard widths for single-leaf doors

  • 1260 mm, at least 1250 mm, at most 1290 mm
  • 1510 mm, at least 1500 mm, at most 1540 mm
  • 1760 millimeters, at least 1750 millimeters, at most 1790 millimeters
  • 2010 mm, at least 2000 mm, at most 2040 mm

Tip: make a stencil

Four accurately sawn boards make it easy to create a precise template. But always stabilize the template with a diagonal strut, otherwise it tilts slightly to the parallelogram. This is a reliable and efficient tool that can control the entire door opening to the appropriate height and width. Small adjustments to the door opening should be made before removing the shell, as this is always associated with a very high level of dirt.

Static construction of a door opening

An opening for a passage is not just a hole in the wall. The opening must be carried out professionally, otherwise there is a risk of collapse.
A door opening consists of masonry, which is interrupted and has a continuous beam at its upper edge. This solid bar is called a "fall". It consists of a standardized concrete block reinforced by two or more long irons. The most important thing in the design of the door opening is that this fall receives sufficient support and also lies around properly. The long iron in the fall serves to absorb tensile forces. These are the largest at the bottom of the fall, as it tends to sag there. If the fall is walled in the wrong direction, ie with the long irons facing up, there is a risk that it will break sooner or later.

Reworking a door opening

If it proves the door opening too narrow for the frame, can still be refinished to a small extent. The maximum amount by which a door opening can be extended depends on the length of the installed lintel. The fall must always have a minimum contact surface of 115 millimeters on both sides. If due to carelessness, lack of skill or a measurement error the door opening is slightly too narrow, it can be carefully extended again. But you only use tools that do not hit the wall. Especially with narrow walls less than 17.5 cm wide there is a risk of collapse.

Tool for extending too narrow a door opening:

Align with the spirit level
  • small cut-off with masonry blade (100 euros in the purchase, 15 euros in the rent)
  • large cut-off with masonry blade (150 euros in the purchase, 15 euros in the rent)
  • about 3 blades (about 12 Euro in a pack of 10)
  • 1 diamond blade for large cut-off grinder (about 12 Euro)
  • Spirit level (about 10 Euro)
  • Pencil (about 1 Euro)

With the spirit level and the pencil, the desired extension of the door opening to the masonry is marked on both sides. Subsequently, the opening is pre-scored with the small cut-off grinder. The cut groove is now the guide for the large cut-off grinder. For 11.5 cm thick walls, the depth of the double-sided cut should be sufficient. If not, the center bar can still be tapped carefully with the aid of a hammer and a chisel. But it is always knocked from top to bottom. Lateral impacts can endanger the stability of the masonry again.

If this correction must be carried out already in the disassembled state of the apartment, much effort should be spent on sealing the place sufficiently. A Verhau from roof battens and building foil may be sufficient for this purpose. When cutting through concrete or masonry creates extremely much dust, which can accumulate anywhere in the home. The better a repair site is protected against the spread of dust, the lower the risk of consequential damage.

Tips for quick readers:

  • Precise planning avoids construction errors
  • Extra long lintels allow a later disseminator
  • check all doors with templates
  • Perform broadening as early as possible, otherwise live
