Picking the right size is essential for a comfortable night’s sleep. Too small, and you might feel cramped; too big, and it could take up unnecessary space in your room. Plus, even if you’ve found the perfect mattress, the wrong bed frame can affect its comfort and longevity.

That’s why we’ve created this bed size guide, breaking down everything you need to know—from dimensions and frame sizes to the best options for your space. Whether you’re looking for a compact single, a spacious double, or a luxurious super king, we’ll help you find the perfect fit for your room and your sleep needs.

UK Bed Sizes Explained

Single Beds (3ft x 6ft 3in / 90cm x 190cm)

A versatile and space-saving option, single beds are ideal for children’s rooms, guest rooms, or smaller spaces. They offer just the right amount of space for one sleeper while keeping the room feeling open.

Small Double Beds (4ft x 6ft 3in / 120cm x 190cm)

Also known as a queen size, this is the perfect in-between option—wider than a single but more compact than a standard double. Great for smaller bedrooms, guest rooms, or solo sleepers who love extra space.

Double Beds (4ft 6in x 6ft 3in / 137cm x 190cm)

The UK’s most popular bed size, a double provides plenty of room for two while still being space-efficient. Whether you're sharing or just love stretching out, it’s a safe bet for most bedrooms.

King-Size Beds (5ft x 6ft 6in / 150cm x 200cm)

If you have the space, a king-size bed gives you extra width and length—perfect for taller sleepers or those who want plenty of room to relax.

Super King-Size Beds (6ft x 6ft 6in / 180cm x 200cm)

The ultimate in luxury and space, a super king offers maximum comfort for couples who want uninterrupted sleep. If you love to sprawl out or want a hotel-style experience at home, this is the bed for you.

Choosing the Right Bed Frame Size

Not sure which size is best for your space? Consider:
✔ Room Size – Make sure your bed leaves enough space for movement and furniture.
✔ Sleeping Style – Do you toss and turn? A bigger bed may be best.
✔ Who’s Using It? – Single for kids? Small double for a teen? Super king for ultimate luxury?

A well-chosen bed frame enhances both comfort and style, so take your time and find the perfect fit for your sleep sanctuary.
