What this door is for
The common American interior door at 762 mm — the same leaf width as the British standard, on a taller frame. Bedrooms and bathrooms in most existing housing.
Three measurements, not one
A door has a leaf size, a rough opening and a clear width, and they are all different. Ordering against the wrong one is the usual way a door arrives that does not fit.
| Millimetres | Inches | What it is | |
|---|---|---|---|
| Leaf | 762 × 2032 | 30 × 80 | The door itself — what you order |
| Rough opening | 862 × 2092 | 33.9 × 82.4 | The hole in the wall, allowing for frame and shimming |
| Clear width | 717 | 28.2 | What you can actually walk through with the door open |
The clear width is the one that matters for getting furniture through and the one accessibility rules are written against — a 30-inch door does not give a 30-inch opening, because the leaf thickness and the stop remain in the way.
Same width, different door
A United Kingdom 762 × 1981 mm has the same 762 mm leaf width and is 51 mm shorter. Matching widths do not make frames interchangeable.

Frequently asked questions
What is the rough opening for a 30 × 80 in door?
About 862 × 2092 mm (33.9 × 82.4 in). The opening has to take the leaf, the frame on both sides and enough slack to plumb it — roughly 50 mm each side and 60 mm above. Never order a door against the size of the hole.
How wide is the actual opening once the door is open?
About 717 mm of clear width. The leaf swings back but its thickness and the door stop stay in the way, so roughly 45 mm is lost. This is the figure accessibility rules are written against, not the door width.
Is a 30 × 80 in the same as 762 × 1981 mm?
The leaf is the same width. A United Kingdom 762 × 1981 mm is 1981 mm tall against 2032 here — 51 mm shorter. The frames are not interchangeable even though the widths match.
Why is 762 mm such an odd number?
Because it is not a metric size. 762 mm is exactly 30 inches, or 2′ 6″ — a British door size from before metrication, converted rather than redesigned. The same goes for the 1981 mm height, which is exactly 78 inches.
