A Guide to Standard Mattress and Bed Sizes in the UK
If you need a new bed or mattress, you might be asking yourself, 'which bed and mattress size is right for me?' A new bed and mattress are an investment, which means that choosing the perfect bed size is a really important decision. In addition, your mattress is a very personal decision, as it needs to suit your space and sleeping style. This guide will break down the different mattress sizes, and bed sizes available, helping you decide which one will fit you and your bedroom best. We also look at the different varieties of mattresses available and which sleeping habits you need to consider to choose the right one for you.

This table is a quick guide to the standard bed sizes, so you know what you're working with. Although we're focusing on standard bed sizes here, we do have a larger bed size guide if you're looking for a bit of extra luxury.

What Size Mattress Do I Need?
We recommend that your mattress is at least 10cm longer than the height of the tallest user. The best mattress size for you should also be wide enough to place your hands under your head without your elbows touching either side of the mattress.
Which Bed and Mattress Size is Right for You?
Small Single Mattresses and Beds
A 2ft6 small single mattress paired with a small single bed is the narrowest choice and is normally the best choice for a young child's bedroom or for those who are petite. Small single mattresses and beds are a great option for a child's first bed and work as an ideal transition bed from a cot. And, if your child does have a small bedroom, then a small single should fit into their space nicely and leave them room to play. They're also ideal for guest rooms or spare rooms that are tight or that work as a multifunctional space, i.e., a study or playroom.
Single Mattresses and Beds
A 3ft single mattress and 3ft bed, on the other hand, are a great standard bed size choice for older children or adults who prefer sleeping alone. In addition, a single mattress and bed fit well into smaller bedrooms where there is less floor space to work with. It's a great choice for a small guest bedroom, too - see our blog post for the best beds for guests for more information. As the most common bed and mattress size for children, a single mattress and bed are perfect for growing children and can be used by toddlers and teenagers.
Small Double (Queen) Mattresses and Beds
A 4ft small double mattress and 4ft bed, also known as a 'queen', is the best mattress and bed size for people who like to sleep on their own but want a little more wriggle room than a single mattress can provide. Many people often get confused about whether a queen is bigger or smaller than a double and the difference between a queen and a double. A queen size bed is wider than a single bed but smaller in width than a double bed, which is why a small double mattress and bed can suit two people sleeping close together as well as solo sleepers.
As such, a small double is probably not an ideal long-term choice for couples. However, queen-sized bed dimensions are a fantastic choice for a guest bedroom where a double bed is just that little bit too big and is a great option when flexibility is needed as it suits both single sleepers or couples without taking up much space.
Double Mattresses and Beds
The standard 4ft6 double mattress and 4ft6 bed are the most commonly used and widely available standard bed sizes in UK homes. A mattress of this size works well for two adults as it provides a comfortable amount of sleeping space while fitting well into most master bedrooms. 4ft6 double mattresses and beds also offer the added benefit of more affordable and a wider choice of linens than larger mattress and bed sizes.
King Mattresses and Beds
A 5ft king size mattress and 5ft bed is the size for couples who desire more sleeping space or for those who are taller and would benefit from the extra 3 inches in length. When asking yourself, 'what size mattress do I need?', consider if you're a light sleeper and your partner is a heavy snorer, or you're a still sleeper, and your partner tends to move and jolt. A king-size mattress and bed offer you a bit more separation. That being said, your king size still needs to fit into your bedroom properly and therefore should only be used in larger spaces; make sure there is enough floor space to move around and make the bed easily.
Super King Mattresses and Beds
For a real sense of luxury, you could get yourself a 6ft super king size mattress and a 6ft bed. This is one of the largest mattress and bed choices available and is perfect for couples who really need their sleep space. It's also an ideal choice if you have children or pets who like to cuddle up with you first thing in the morning! But, again, a bed and mattress this size needs to be used in a larger bedroom, so you still have space to move around the rest of the room.
If you or your partner are tall, we'd recommend investing in a king or super king. In addition, we offer zip and link mattress and bed sizes that are extra-long, so this could be a superb solution if you need that added length.
Will Your Mattress Fit Your Bed Frame?
While you might think that bed sizes and mattress sizes are the same, it's not always true. Many bed frames are not made to be the same width and depth as the mattress sitting on top of it; they are designed to fit around the mattress. They then take up extra space in your bedroom. Take a tape measure to confirm the size of your bed frame, or if it hasn't arrived yet, see if you can find the dimensions online.
Top tip: Divan beds are a fantastic choice that offers a solution; their advantages make them a firm favourite across the UK and further abroad because they are designed to align with standard bed sizes, saving you space and hassle.
Other Things to Consider:
Now that we've explained the different mattress sizes available, we're going to highlight seven key considerations that you should keep in mind before deciding what the best mattress size is for you.
1. Are you a light sleeper?
If you share a bed with a partner, their sleeping habits can greatly impact your sleeping pattern and sleep quality. In turn, this can influence your mood. For example, a light sleeper may find it harder to drift off if their partner snores heavily or moves about a lot. If this is the case for you, consider upgrading your bed size to a king or super king to get some much-needed space.
Alternatively, if you're an active sleeper that sleeps solo, it might be worth opting for a bigger mattress, such as a 4ft6 double mattress, so that you have space to move about without the risk of falling onto the floor!
2. What mattress type will work best for you?
Mattress size is definitely important, but so is mattress type! Choosing the perfect mattress material depends on your needs and firmness preferences.
3. Will your mattress fit the space in your bedroom comfortably?
Your bed is the most important feature of your bedroom, and so it should take priority when arranging the furniture in your space. Of course, you can always move your existing furniture around to discover the ideal place for your new mattress. Also, ensure to take a tape measure and carefully measure out the floor space you have dedicated to your bed.
The best mattress size will leave at least a foot of bedroom space on either side of your mattress; this will leave you with enough room to comfortably get out of bed in the morning and easily change your bedding.
4. Can you find linen to go with your mattress?
When it comes to picking out the perfect bedding and linen (such as duvets, valances, and loose or fitted sheets) for your mattress, you need to think about pricing and accessibility. Typically, the larger the bed linen, the more expensive it is.
It is also worth noting that non-standard bed sizes are usually less readily available, so you may have limited options.
If you share a bed but struggle with duvet hogging, you could always opt for a duvet that's a size up from the mattress size. This means that there's much less pulling the duvet back from each other because you'll have plenty of duvet for you both!
5. Can you manoeuvre your mattress into your bedroom?
Even if you have the bedroom space for a larger mattress, if you don't have the space to get the mattress into your bedroom physically, then you're going to struggle! Before finalising your mattress selection, plan out how you and the delivery people will manoeuvre your mattress into your bedroom. You may need to measure out your doorframes and the width of your staircase or hallway.
A fantastic solution to this problem is opting for a zip and link mattress. Two single zip link mattresses can be more easily manoeuvred through tight spaces, and they are much lighter than a double size or king size mattress.
