What Is the Biggest Bed Size in the UK?
The largest standard bed size commonly sold by mainstream UK retailers is a super king, measuring 180 x 200 cm. However, several much larger bed sizes are available.
Our range includes Small Emperor, Emperor, Caesar and Super Caesar beds, but the biggest size bed we make is 365cm wide.
Your choice depends on the number of people sharing, the space available in the bedroom and how much personal sleeping space everyone prefers.

What Bed Sizes Are Bigger Than a Super King?
If a super king does not give you enough room, the next step is usually a Small Emperor or Emperor bed. Caesar and Super Caesar beds provide considerably more width and can be ideal for families or couples who want generous personal space.
- Small Emperor: a square 200 x 200 cm bed
- Emperor: at 215cm wide, our most popular size
- Caesar: at 245cm wide this is our largest standard size
- Super Caesar and above: sometimes too large for UK homes
- Made to measure: for unusual room sizes or specific requirements
We can also help with matching bedding, bed linen and accessories for these less common sizes.
What Is a Family Bed?
A family bed is an extra wide bed chosen to provide room for parents, children and sometimes pets. It is not one fixed UK size, so the dimensions depend on how many people may share the bed and the size of the bedroom.
Emperor, Caesar and Super Caesar sizes can all work as family beds. A bespoke size may be more suitable when you have a specific bedroom width or need additional length.
For Couples
More personal sleeping space and less disturbance from your partner's movement.
For Families
Extra room for morning cuddles, story time or occasional family sharing.
For Tall Sleepers
Combine extra width with additional length for a more comfortable night's sleep.
