726 × 2040 mm door
726 × 2040 mm
28.6 × 80.3 in · 2′ 5″ × 6′ 8″ · United Kingdom
What this door is for
The metric range middle size. Common in houses built since the 1990s, and the reason a replacement door bought by eye often turns out 59 mm too short.
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 | 726 × 2040 | 28.6 × 80.3 | The door itself — what you order |
| Rough opening | 826 × 2100 | 32.5 × 82.7 | The hole in the wall, allowing for frame and shimming |
| Clear width | 681 | 26.8 | 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 28.6-inch door does not give a 28.6-inch opening, because the leaf thickness and the stop remain in the way.

Frequently asked questions
What is the rough opening for a 726 × 2040 mm door?
About 826 × 2100 mm (32.5 × 82.7 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 681 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.
What is a 726 × 2040 mm door used for?
The metric range middle size. Common in houses built since the 1990s, and the reason a replacement door bought by eye often turns out 59 mm too short.
What height is a 726 × 2040 mm door?
2040 mm (80.3 in). This is the taller genuinely metric British range, 59 mm above the old 1981 mm imperial standard — the two do not interchange.
