Mattress & Bed Sizes

Your mattress is one of the most important elements in your home, so it's worth investing in one that will give you years of comfort and support.

When buying a new mattress there’s a lot to think about; how much should you spend on a mattress? Should you choose memory foam or pocket spring? But one of the most common dilemmas is which size mattress to choose.

Mattresses and beds come in a range of dimensions to suit different needs and choosing the right one can be the difference between a good and bad night’s sleep.

Here are some of the most common bed and mattress sizes available in the UK.

Mattress Size Width x Length (cm) Width x Length (ft)
SINGLE 90 x 190 3 x 6.3
SMALL DOUBLE (QUEEN) 120 x 190 3.11 x 6.3
DOUBLE 135 x 190 4.6 x 6.3
KING 150 x 200 5 x 6.6
SUPER KING 180 x 200 6 x 6.6

Single - 90x190cm

Often the choice for kids and teens’ rooms, single mattresses are a great space saving option while still providing plenty of room for a growing child. Single beds and mattresses are also a common choice for a guest room or spare bedroom.

Small Double - 120x190cm

Sometimes known as queen size or three quarter, a small double is wider than a single but narrower than a double. A small double bed is ideal for growing teenagers or people who need a bit more space than a single bed. They’re also a cosy option for couples, when there’s not enough room for a full sized double bed.

Double - 135x190cm

A standard double mattress is designed to sleep two adults comfortably. Double beds are a great option for couples moving into their first home, providing plenty of comfort and space while costing less than a king size. Double mattresses aren’t just for couples though – they’re a good option for individuals who want more room too.

King - 150x200cm

King size beds and mattresses are a popular choice for those who have the space to accommodate them. Slightly wider and longer than a double, they take up more floor room but offer a little extra comfort and space to move around.

Super King - 180x200cm

A super king size bed offers extra width than a king size and is the ultimate choice if you’re looking for a spacious and relaxing sleep space. Super king size provides plenty of room for a couple to sleep without disturbing each other and for those with kids, they’re big enough for the whole family to enjoy a lazy Sunday morning together.

Tips for choosing the right size mattress

  • It might sound obvious but don’t forget to measure your bedroom before you buy a new mattress and bed. On one hand, you need to make sure your new bed will fit, but on the other hand, there might be room for a bigger bed than you expected.
  • Make sure your mattress is big enough for the tallest person using it. Allow for 10cm room at the bottom of the bed to avoid cold feet at night.
  • Ideally, a mattress should give you enough space to stretch and move around at night, especially if you sleep with a partner. Try lying on the mattress and putting your elbows under your head – if they hang over the edge or touch the other person, you may need a bigger size.

UK Bed Sizes

UK beds are designed to be used with standard UK mattress sizes and will usually be labelled as single, double, king size, or super king size in accordance with which mattress they can hold.

However, the actual size of the bed frame can differ depending on the design of the bed and the width of the frame. For example, a double bed frame will usually be larger than a double mattress. When measuring for a new bed, always take into account the total dimensions of the bed frame itself, not the mattress size.
