The side of the front door on which the hinges – i.e. the movable connection between the door leaf and frame – are attached is referred to as the hinge side.
To determine which hinge a door has, stand on the side where the hinges can be seen when it is closed.
If these are on the left-hand side in the plan view, then the door is hinged on the left; if they are on the right-hand side, the door is hinged on the right.
The choice of a front door hinge is already made during the planning phase for the construction and depends, among other things, on the likely routes of the residents and any furniture in the hallway.
Doors with different openings are usually found in every apartment in order to make the best possible use of the available space.
In order to ensure that manufacturers, distributors and buyers of doors can communicate with each other without errors and that there are no problems during installation, the front doors must be precisely identified according to the direction in which they open. The need for the designation includes the alignment of:
The directional designations are clearly regulated in Germany by the DIN standard 107.
For this reason, the terms "DIN left" and "DIN right" can be found in the specifications for each front door model in order to avoid incorrect orders.
When buying front doors – but this also applies to interior doors – you should definitely pay attention to the corresponding designation to ensure that door leaves, frames and hinges really do fit together and are installed so that they open in the same direction. Especially in the case of custom-made products with special dimensions, a mistake can quickly become expensive.
