Super King duvet size
260 × 220 cm
102 × 87 in · United Kingdom · fits a 180 cm Super King bed
About this size
The largest standard British duvet. At 260 cm it is close to the American king comforter, which is the only place the two systems nearly meet.
How much it hangs over
A duvet is not the size of the bed and is not meant to be. This one is 80 cm wider than the mattress, so it drops 40.0 cm on each side.
| Duvet width | 260 cm · 102 in |
| Length | 220 cm · 87 in |
| Mattress width | 180 cm |
| Overhang per side | 40.0 cm |
| Area | 5.7 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.

Frequently asked questions
What size is a Super King duvet?
260 × 220 cm, or 102 × 87 inches.
Why is a Super King duvet wider than a Super King bed?
Because it has to hang over the sides. The bed is 180 cm wide and the duvet is 260, which leaves 40.0 cm on each side. Less than about 25 cm and the cover rides up and exposes the mattress whenever anyone turns over.
What bed does a Super King duvet fit?
A Super King bed, 180 cm wide. Its full dimensions are here.
What size duvet cover do I need?
The same as the duvet: 260 × 220 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.
