Choosing the right bed size might seem simple, but it’s one of the most common decisions people second-guess after buying. Go too small and you’ll regret it every night. Go too big and suddenly your room feels like it shrunk.
Whether you’re upgrading your own bed or shopping for a guest room, this guide by Funkybedz breaks down everything you need to know about UK bed sizes with no jargon and no fluff.
UK Bed Sizes Explained
Here’s a quick look at standard UK bed sizes and who they’re best for:
Single Bed – 90 x 190cm (3ft x 6ft 3in)
A good fit for kids, teenagers, or smaller guest rooms. It’s compact but still gives you enough room to sleep comfortably; just don’t try to share it.
Small Double – 120 x 190cm (4ft x 6ft 3in)
Also known as a three-quarter bed. Great for solo sleepers who want a bit more space without taking over the whole room. Can work for two people... but only just.
Double – 135 x 190cm (4ft 6in x 6ft 3in)
The UK’s most popular size. Comfortable for one, manageable for two especially in average-sized bedrooms. This is often the go-to for couples.
King – 150 x 200cm (5ft x 6ft 6in)
More width, more length, more legroom. If you’re tall, fidgety, or just want more breathing space, a king-size bed is a game-changer.
Super King – 180 x 200cm (6ft x 6ft 6in)
This is luxury. Perfect if you’ve got a spacious bedroom and want hotel-style comfort every night. It's also ideal if you’ve got pets or kids who sneak into bed.
Measure Twice, Buy Once
Before you fall in love with a Funkybedz online, make sure you measure properly and not just the floor space.
Here’s what people often forget to check:
Room to walk around the bed - you’ll want at least 60cm on each side if you can
Stairs and doorways - can the bed frame or mattress actually fit into the room?
Headboard height - awkward if it blocks a window or hits a sloped ceiling
Existing bedding - new bed size might mean buying all new sheets and duvets
Top tip: use masking tape to mark out the size of the bed on your bedroom floor. It’ll give you a quick feel for how much space it’ll take.
Matching Bed Size to Room Type
If you’re not sure which size suits which room, here’s a quick guide:
Small Bedrooms → Single or Small Double
Standard Rooms → Double or King
Master Bedrooms → King or Super King
Guest Rooms → Single or Small Double (unless you’re showing off)
If you’re tight on space but still want storage, consider an ottoman or divan bed with built-in drawers. They give you more flexibility without eating up the whole room.
Solo vs Shared: Who’s Sleeping Where?
It’s not just about size - it’s about sleep habits.
Solo sleepers can often manage with anything from a Small Double upwards
Couples might feel cramped in a Double unless they’re used to it
Tall or restless sleepers will appreciate the extra length and space of a King
Sharing with kids or pets? Super King is your friend
