Who is a Small Double bed for?
A Small Double gives one sleeper much more width than a Single. It is 15 cm narrower than a Double, so it can fit rooms where a Double is too wide.
How much room do you need for a Small Double bed?
Leave about 50–60 cm to walk beside the bed and at the foot if your room allows. That is a useful target, not a rule.
| Layout | Room width | Room length |
|---|---|---|
| Both sides free | 220–240 cm | 240–250 cm |
| One side against a wall | 170–180 cm | 240–250 cm |
Add the extra size of the frame and headboard. Divan bases are usually close to the mattress size; wooden bedsteads, sleigh beds and wide headboards are bigger. Try the bed room planner with your own numbers.
