Interior door dimensions: how to measure the structural opening correctly
The right dimensions are the foundation. If you make a mistake when measuring, the door will not fit. We explain what the interior door dimensions are and how to measure the structural opening.
Common door widths
Common door widths are 60, 70, 80, 90, 100 and 110 cm. Width only affects the price: prices in the door visualizer are given for a width of 60 cm, and for every additional 10 cm we charge €3 to €4 for material.
1. Width of the structural opening
The structural opening must be 6 to 8 cm wider than the door leaf. For a 70 cm leaf you therefore need an opening of 76 to 78 cm, and for a 90 cm leaf an opening of 96 to 98 cm. Measure the opening in several places, because it may be wider in some places than in others. The smallest measured value decides.
2. Height of the structural opening
The height is measured from the finished floor, or from the height of the future floor. The ideal opening height is 200 cm, at most 225 cm.
3. Wall thickness
Measure the thickness at the bottom, in the middle and at the top. The door frame can adjust by approximately 1 cm, so if you measure 20.5, 20.8 and 20.6 cm, the frame will be adjusted to a sensible average.
Leave the measuring to us
Since we make made-to-measure interior doors, we measure every opening in person and free of charge. You pay no extra for a non-standard size. While measuring, we will also determine the opening direction with you (right-hand or left-hand doors). If you have an old steel door frame, see steel frame cladding.
