Twin XL comforter size
173 × 234 cm
68 × 92 in · North America · fits a 97 cm Twin XL bed
About this size
The dormitory size: the same width as a twin with four extra inches of length to cover the longer mattress.
How much it hangs over
A comforter is not the size of the bed and is not meant to be. This one is 76 cm wider than the mattress, so it drops 38.1 cm on each side.
| Comforter width | 173 cm · 68 in |
| Length | 234 cm · 92 in |
| Mattress width | 97 cm |
| Overhang per side | 38.1 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.
