Did you know that the average person will spend around 25 years asleep throughout their lifetime? So, you’ll want to pick a comfortable mattress which gives you the support you need to sleep soundly!

Mattresses come in all shapes, sizes and styles so it can be difficult to know which to choose.

If the range of mattress sizes leaves you confused, our complete guide to the different ones on the market today should assist.

Tips for choosing the right size

  1. When selecting a mattress size, make sure that the length is at least 10cm longer than the tallest person using the bed and the width is wide enough for you to spread out.
  2. If you’re offered the option of European mattresses, remember their sizing is different to standard UK widths. EU bed sizes tend to be slightly larger in both length and width.
  3. If the standard sizes aren’t right for you, we can create a custom size mattress for you to fit any specification.

Small Single Beds

When space is limited in your home, then a small single bed can certainly fit the bill. They tend to be a tad smaller than the average single bed, and are usually shorter in length rather than width.

Perfect for young children and adolescents, on average they measure around 2’6” x 6’3”, guaranteeing that there’s plenty of space available to roam around and use for other furnishings.

For anything smaller, consider investing in a twin size mattress.

Single Beds

There isn’t a lot of difference between small single beds and single beds – in most cases, a matter of six inches. The standard single bed dimensions are 3’0” x 6’3”, and are one of the most common mattress types in the UK, for families with children in particular.

These mattresses can fit almost any average single bed frame, and come in a range of different materials and fillings, from cotton to cashmere.

Queen Size

A fantastic solution for when there’s no space for a double bed in your bedroom is purchasing a queen size mattress.

This type of mattress is regarded as a small double and gives users enough space to sleep, whilst being an excellent space-saver.

Mattresses of this type usually measure around 4’0” x 6’3”, making them considerably wider than single beds.


Along with single mattresses, double mattresses are one of the most popular mattress types on the market.

There is only six inches in between mattresses of this kind and a queen size mattress. A double mattress usually measures 4’6” x 6’3”, and there are many custom options available on bespoke mattresses to cater to all tastes and comfort requirements.

King Size
