Bed Size Guide

It may seem like we're stating the obvious, but when choosing a bed, it's essential to find the right size for your needs.

Do you want a single, double, king size or even a superking size bed? More importantly, what's the difference between all these bed sizes?

There's a lot to think about, so to help you out, we've compiled a comprehensive guide to bed sizes to get you on the right track.

Standard UK bed sizes

Bed sizes are actually based on their matching mattress size. This means that standard bed sizes are really just referring to the size of the mattress that fits the frame.

Here are the standard sizes for mattresses in the UK:

Size Dimensions (imperial) Dimensions (metric)
Small Single 2'6" x 6'3" 75 x 190cm
Single 3'0" x 6'3" 90 x 190cm
Small Double 4'0" x 6'3" 120 x 190cm
Double 4'6" x 6'3" 135 x 190cm
King Size 5'0" x 6'6" 150 x 200cm
Superking Size 6'0" x 6'6" 180 x 200cm

You should bear in mind that the actual bed frame will be larger, so consider this if you're trying to fit your bed into a particular space or room. For example, a sleigh bed has a large headboard and foot end, which will take up more space than a minimalist ottoman.

IKEA/European bed sizes

European or IKEA bed sizes differ slightly to UK versions, though they are still based on mattress size.

Here you can find standard European mattress sizes:

Size Dimensions (imperial) Dimensions (metric)
Euro Single 3'0" x 6'6" 90 x 200cm
Euro Small Double 4'0" x 6'6" 120 x 200cm
Euro Double 4'7" x 6'6" 140 x 200cm
Euro King Size 5'3" x 6'6" 160 x 200cm

Euro mattress sizes are slightly longer than UK ones, and their double and king size versions are wider, too. These mattresses can usually be paired with IKEA bed frames.

Always check with the manufacturer before you purchase a bed, so you know you're getting the right size for your home.

Which bed size is best for my sleeping arrangements?

When deciding on the right-sized bed, a good night's sleep should be your main priority. A bigger bed will always offer much more space and comfort, especially if you're sharing with a partner.

Whether you sleep alone or share with someone else, read our advice on choosing the best size for your sleeping arrangements.

  • For a cosy night's sleep:
    A regular double is probably the way to go. These beds are 135cm wide, giving you space to spread out while keeping nice and cosy.
  • For a bit more personal space:
    The minimum you'll be looking at is a king size bed which gives you a bit more room for manoeuvre when sharing a bed with a partner.
  • If you like to fully spread out:
    If you want the joint benefits of sharing a bed combined with the freedom to spread yourself out, you're going to want to look at a superking size bed. They're an impressive 180cm in width, so you're guaranteed plenty of space to yourself.

If you're unsure of which bed is best for you, please get in touch with our team for some tailored advice.

Which bed size is right for me?

Now that you have a better idea about which sized bed will suit your sleep needs, here's some more information about each different size to help you make the right decision.

Superking size bed

If you have plenty of floor space (and value your space in bed), it's definitely worth investing in a luxury superking. As well as making a visual statement in the bedroom due to its impressive size (180cm x 200cm), there's no better bed to really spread out in and enjoy a good night's sleep.

King size bed

King size beds are 150cm x 200cm, which makes them ideal if you want the additional room to stretch out. If you have the space and the budget, we recommend choosing a king size bed over a double because they offer much more room per person.

With the extra 10cm length, the king size is also a great choice if you're tall, increasing both comfort levels and that all-important leg room.

Double bed

The most popular bed size in the UK, the standard double bed is a good size for two adults. At 135cm x 190cm, it will fit well into a standard bedroom without overcrowding. A double bed is also ideal for visitors if you have a spacious guest room.

Small double bed

A small double is a savvy option for couples with limited space - provided you don't mind sleeping close together.

At 120cm x 190cm, these beds are perfect for growing youngsters or if your kids like to stretch out. It's also the perfect size for a guest bed as it's unlikely to take up an entire spare room.

Single bed

Single beds are usually 90cm x 190cm which makes them perfect for solo sleepers, box rooms or guest rooms. They're a great investment for your children and teens, offering years of quality sleep.

Small single bed (child's bed)

Younger children will usually feel cosier and more comfortable in a small single bed. These are also good for smaller rooms, or where two young children have to share (and bunk beds aren't a practical solution).

Choosing the right-sized bed is important, but you also need to find a matching mattress that perfectly fits. Read more of our helpful tips and advice on how to choose the best mattress, as well as what size is right for your bed.
