Selecting the perfect bed size is not easy. With feet to inches to centimetres, it can often feel like codes. But don’t worry, we’ve compiled it all into a simple, easy-to-understand guide so you can choose the right bed and mattress without the headache.
How UK Bed Sizes Work
The mattress that the bed is designed to accommodate determines its size. In other words, the mattress size you select will dictate the frame size you require. Many bed sizes in the UK are named after the width of the mattress (in feet) but also have a metric equivalent (in centimetre’s).
| Bed Type | Width × Length (Feet) | Width × Length (cm) |
|---|---|---|
| Single Bed | 3'0" × 6'3" | 90 × 190 |
| Small Double Bed | 4'0" × 6'3" | 120 × 190 |
| Double Bed | 4'6" × 6'3" | 135 × 190 |
| King Size Bed | 5'0" × 6'6" | 150 × 200 |
| Super King Size Bed | 6'0" × 6'6" | 180 × 200 |
Note: Bed frames are usually a bit larger than the mattress itself, especially if they have headboards, footboards or storage units. So always check UK bed sizes dimensions before buying.

How to Choose the Right Bed Size for Your Bedroom
Selecting the correct size of bed is more than just picking a product that looks good on the website and has it shipped to your doorstep. It involves ensuring that the new bed you purchase is a perfect fit for your room and your entire bedroom design.
Before you make your decision, take the time to measure your room. Take into consideration the width, length, and ceiling height. You should also think about the headboard design you want, whether it is the tall wingback headboard or the floor-standing headboard.
It is also important to consider room design. If your bedroom is small, a larger frame may dominate the room. This is especially important when considering functional designs such as divan beds or ottoman beds, which are designed with storage in mind. Although these beds are great for maximising space, you will still require sufficient space to open drawers or lift the ottoman mechanism.
Ultimately, the best size for a bed is one that complements both the size of the room and the lifestyle. Measure well and choose a design that provides both comfort and functionality.
