What "custom height" means

Every door starts at the standard height of 80" (6 ft 8 in), which fits almost every doorway. Choose Custom Height if your opening needs a shorter door, and we cut it down for you. Here is how it works:

• Yes: type the finished height you need, anywhere from 75" to 80" (for example, 77"). We trim the door to that size, taking the height off the bottom edge so the door still looks right.
• No: keep the standard 80" height.

When you might need it

Older homes, openings under stairs, or rooms where new flooring (tile or hardwood) raised the floor and shrunk the opening.

How to measure

Measure from the underside of the top of the frame straight down to the finished floor (the floor surface you walk on, not the bare subfloor underneath). Then subtract about 1/2" to 3/4" so the door can swing clear of the floor. The result is your door height. If it comes out above 80", just keep the standard height; if it comes out below 75", contact us before ordering.

Keep in mind: a door can always be trimmed shorter, but it can't be made taller. If you're between sizes, measure twice before ordering.
