Do you want to install a door with a door frame? You must first measure the height and width of the opening.

Fixed door frame or adjustable door frame?

Once you’ve determined the dimensions of the door opening, you need to consider the type of door frame. Fixed door frames, which have a constant width and height, are available on the market. They’re most commonly used in newer construction. The second type is an adjustable door frame. This type of door frame is typically installed in buildings with non-standard wall thicknesses. An additional advantage is the included cover strips.

Door Opening Dimensions

The dimensions of door openings depend, among other things, on the type of door frame. For a fixed door frame with a 90-width door, the opening should be 101 cm wide and 207.5 cm high. In contrast, with an adjustable door frame, the door opening should be 98 cm wide and 206 cm high.

Is the door opening too large? You can reduce its size using a special mortar. It’s more difficult if the door leaf is too narrow. In that case, you can widen the opening—provided it’s not a load-bearing wall. Another option is to try exchanging the door with the retailer.
