I was frustrated when I bought a mattress for my UK sized bed only to realise it was the wrong size. The names for mattress sizes don’t give you the actual size. Also shops like IKEA don’t use the standard UK sizes. I put the following table together so you can see all UK mattress sizes.

The above charts the regular UK bed mattress sizes in inches and feet as well as centimetres lengths and scales in a mattress sizes chart. From single bed mattress sizes right through to super king sizes. This chart detailing mattress sizes from smallest to biggest will enable you to run a mattress size comparison in order to choose the best mattress for you whether its in feet and inches or CM. Especially important to understand the size dimensions of the mattress if you are buying a quilt, bed linen or any kind of bedding as they vary. With this in mind I created a table which shows you all the measurements compared and who they are ideal for:

For standard mattress sizes UK check the above bed mattress sizes chart which lists all the standard regulation English and UK mattress sizes that apply to foam, divan and sprung mattresses along with the measurements in a handy guide for use when you are choosing bed mattresses. If you are looking to purchase an IKEA mattress and are worried it might not fit the dimensions of your bed check out the IKEA mattress sizes guide to work out the scale of the mattress widths and mattress lengths as they aren’t regular to UK mattress sizes. If you are looking for bed sizes I’m afraid there isn’t a chart for this as there isn’t a standard for bed sizes they are all bespoke as I explained in my bed sizes page.

Mattress sizes comparison

As you can see mattress sizes are defined by a name and below is the hierarchy from smallest to largest using a specific name rather than a number. These mattress names are a standard and there shouldn’t be any variance, however there may be a variation in dimensions dependent on the bed used. Bed widths as defined by the top to bottom vary by supplier. To see how the different sizes compare have a look at the following diagram which shows each mattress size by order. As an explanation of this in picture format I have produced the following graphic which shows each mattress name side by side from smallest to biggest so you can make a mattress size comparison:

UK bed mattress sizes

To ensure that you get the comfort and a good nights sleep you are looking for check the sizes and consider your body length before purchasing. Make sure its long enough for your height and wide enough to accommodate whomever is sleeping in the bed. The difference between the different standard mattress sizes could mean the difference between being comfortable compared with being uncomfortable. And that means not sleeping properly!

Obviously your bedroom dimensions will also come into play but bear in mind that the bed itself will determine the space required not the mattress unless of course you intend to just use a standard divan bed base which will typically only be a fraction wider than the mattress itself. Standard bed sizes charts don’t exist as their are no standards for the bed. If you are using a standard box base then the size of the bed will be the same as the mattress.

King size mattress & bed dimensions & measurements

Bed dimensions aren’t standardised however any decent retailer like this one will detail the dimensions of each bed. The standard king size bed mattress dimensions in metric are 150 cm (1 metre 50 cm) in width and 200 cm (2 metres) in length. The size in imperial is 5 feet in width and 6 feet 6 inches in length. This represents the standard full size typical dimensions in the UK. Any other dimensions such as width, height or weight will be entirely dependent on the manufacturer, construction and model of mattress. A king size mattress compared to a queen size mattress (also referred to as a small double mattress) is 30 cm wider and 10 cm longer in metric, 1 foot wider and 3 inches longer in imperial measurements.

If you are making a quilt, throw, blanket, duvet or a bed runner you will need to know the mattress width which isn’t standardised so you will need to check with the retailer or manufacturer. Buying headboards or footboards will be dependent on your taste but they will need to be at least the width measurement mentioned above.

Beds and mattresses for tall people

Checking out the right length of mattress is especially important if you are a tall person. If you are under 6ft 6 inches then the typical larger size mattresses should be adequate to accommodate your longer body. The biggest standard mattress size is the Super King-size at 6 ft 6 inches or 180cm by 200 cm even bigger than a king size. If you are very tall however and more than 6 ft 6 inches then the best option would be to consider a custom bespoke mattress and bed which are available to make sure its comfortable enough. That is unless you don’t mind sleeping diagonally or with your feet hanging off the bed.

You will find that the standard UK mattress dimensions shown here will be too small to accommodate your body. Obviously upgrading the mattress will mean upgrading the bed frame too. Be careful if you intend on getting a bed with a footboard or a headboard as these will often mean the difference between a bed fitting your body length and not. If you go for a custom bed remember you will need to get custom bedding too that means custom fitted sheets and covers.

Mattress depth sizes

As with bed sizes there is no mattress depth standard. Different types of mattresses will have different depths that range typically from 9 inches (22.86 centimeters) to 16 inches (40.64 centimeters) depending on how they are manufactured or the type of mattress construction. A pillowtop mattress with its extra layer of comfort will increase the depth further. The actual thickness of your mattress shouldn’t make a huge amount of difference as the effect can be offset by the height of the bed if you are looking to adjust for ease of getting into bed. If you are looking to buy bed sheets however you will need measure the dimensions and depth of the mattress. Dependent on the thickness of the bed you may also need deep pocket sheets to get the sheets to fit.

What are IKEA & non standard mattress sizes?

If you are looking for IKEA mattress sizes check this IKEA mattress sizes chart. Many retailers will go much bigger than the king size and even super super king size mentioned above. Be warned that the king size bed dimensions will be significantly larger with certain retailers taking up a lot of space in your bedroom. Getting an extra long or full size mattress that will fit you might mean you need to get it custom made. There are retailers that will make both custom dimension beds and mattresses. If you are concerned with a hotel mattress size I would recommend checking with the hotel manager before you book or your feet might be hanging of the end of the bed!

Children grow up fast so its best to provide something that they can grow into. There is little point in buying a small kids mattress when they will grow out of it increasing the price of the bed and mattress long term.

About bed sizes UK

The above chart shows the standard mattress sizes and dimensions for bed mattress sizes in England and the UK. This will serve as a measurement guide if you intend to buy your mattress in Britain. This is not a UK bed sizes chart, bed size guide, bed dimensions chart or bed size scale as there is no standardisation and British beds come in varying sizes just as they do in any other country. If you are looking for a British bed size guide, bed sizes in feet and inches or bed sizes in cm I would suggest checking out the bed in person with a tape measure to check that there isn’t any feature of the bed frame that requires more space. Some retailers will stock odd sizes using an odd European dimension or other special measurements. Be sure to clarify with the stockist before you purchase.

What are futon mattress sizes?

Futons don’t use conventional sprung mattresses and have a folded mattress topper which forms the basis of the couch. There are many Futon producers many of which are completely custom made. As a result of this futon mattress sizes when extended into ‘bed mode’ don’t tend to follow any kind of standard mattress size format. As the mattress has been custom made for the futon frame if you want to buy a replacement mattress for the futon you will need to contact the original futon producer. When the futon is folded into ‘couch mode’ again there are no standard sizes. For each futon check with the futon supplier for size and dimensions when folded and when extended to a bed. Other bespoke beds such as trundle (also known as trumple beds, truckle beds or hurly-beds) will also need to be looked at on a case by case basis. The twin beds will need to be measured individually both the top bed and the slide out bed if it is being used as a bed rather than storage space.

Standard Bed Sizes UK Dimensions & Measurements

I am writing this just to be clear that there is no standard for bed sizes. Each manufacturer will have slightly different dimensions. It is wise therefore to check with the specific manufacturer or retailer before planning where to put the bed. Bed frames will also be slightly different by manufacturer. Bed mattresses on the other hand are standardised, if you are looking for this then head to our bed mattress sizes pages which contain mattress charts so you can compare the sizes. For a quick bed mattress size comparison check out our mattress size comparison page.

Bed size comparison

Bed size comparison will need to be taken on a case by case basis. As mentioned below there are no standardised bed mattress sizes. The best thing to do is to go along to the store with the tape measure to get a true idea of what the dimensions are and then check the mattress size and measurements against the bed. Websites will sometimes quote the bed sizes but there may be odd elements to the bed that will increase the amount of space required. If you check the UK mattress sizes here against the bed fitting you will see whether it fits.

If you are looking for bed size comparison source it is a bit tricky as there is no standard for bed sizes; they come in a huge range of shapes and sizes. What is standardised however is the mattress. A quick mattress size comparison can be carried out by checking the following graphic or check out our specific mattress sizes information. Be careful if you are buying an IKEA mattress as they use European sizes as detailed on our IKEA mattress sizes page.

IKEA Bed Sizes

As with any bed the actual dimensions will be slightly different based on the type of bed. IKEA beds are no different so if you want to know the exact bed size its best to check with each model. Mattresses do however have a standardised sizing and IKEA beds are designed to fit European size mattresses not regular UK size mattresses. Check this page if you are looking for what size of mattress you need for an IKEA bed. The chart shows all of the standardised IKEA mattress sizes.
