Double duvet size
200 × 200 cm
79 × 79 in · United Kingdom · fits a 135 cm Double bed
About this size
The UK double, and the size most British households own. It is square: 200 × 200 cm, so it can be turned either way, which no other UK size allows.
How much it hangs over
A duvet is not the size of the bed and is not meant to be. This one is 65 cm wider than the mattress, so it drops 32.5 cm on each side.
| Duvet width | 200 cm · 79 in |
| Length | 200 cm · 79 in |
| Mattress width | 135 cm |
| Overhang per side | 32.5 cm |
| Area | 4.0 m² |
Under about 25 cm of overhang the cover rides up as soon as anyone turns over, which is the real complaint behind "the duvet is too small" — usually it is the right size for the bed and the wrong size for two people.

What size is a Double duvet?
200 × 200 cm, or 79 × 79 inches.
Why is a Double duvet wider than a Double bed?
Because it has to hang over the sides. The bed is 135 cm wide and the duvet is 200, which leaves 32.5 cm on each side. Less than about 25 cm and the cover rides up and exposes the mattress whenever anyone turns over.

A Double bed, 135 cm wide. Its full dimensions are here.
What size duvet cover do I need?
The same as the duvet: 200 × 200 cm. Covers are sold to match the insert, not the bed — buying a cover by bed size is the usual reason one arrives too small.
