Are you planning to renovate your apartment? Wondering how to measure a door to avoid buying the wrong one? Read this article to find out what you need to know before you get started.
Many people may think they know how to measure a door, but errors often occur when taking measurements on their own. It’s therefore worth knowing how to prepare properly for this task.

Adjustable or fixed door frame? What is its function?
A door frame is the finish for an opening in the wall. The door panel is installed within it. It also serves as an additional seal and keeps the door in the correct position. Door frames are increasingly serving a decorative purpose. Stores often carry door frames with a lacquered finish. Before purchasing one, you should measure the door opening. There are two main types of door frames: fixed and adjustable. The former have fixed dimensions, while the latter can be adjusted to accommodate non-standard heights and widths of door openings. Adjustable door frames are considered versatile and easier to install.

How to measure a door? Correct measurement
If you plan to replace a door without a door frame—measure its width and height without the trim. When installing a door and door frame, determine the following dimensions:
- height—measure it in three places: from the floor to the ceiling—the smallest measurement will be the correct one;
- width—measure at six different points and use the smallest measurement;
- wall thickness—you’ll need this to select the right door frame; measure at several points along the vertical studs and choose the widest measurement (take into account all finishes, such as tile and wall paneling).
Incorrect door opening dimensions—what to do?
It may happen that the dimensions of the door openings turn out to be incorrect. If they are too large, you can simply reduce them using special mortar. Unfortunately, if the opening is too small, the situation is more complicated. You can try to cancel the door order or modify the doors, which can be troublesome. The second option is to widen the opening. In this case, you’ll need to check the type of wall. If it’s a load-bearing wall, you’ll need to consult the appropriate authorities before proceeding. With partition walls, you can change the dimensions as needed, but this will involve additional work.

Installing the door leaf—right- or left-handed?
Fitting a door also involves determining which way it should open. Both left- and right-hand doors are available. The difference is that left-hand doors have hinges on the left side and open to the left, while right-hand doors have hinges on the right side and open to the right.
