Selecting the appropriate bed and mattress size is essential when refreshing your bedroom. However, with so many sizes and types available, this can feel daunting. This guide will make the process easier, detailing everything you need to know about bed sizes in the UK and who they are most suited for.
Understanding Bed Size Measurements
When shopping for a bed or mattress, it’s essential to understand that metric and imperial sizes are not always exact equivalents. There can be a tolerance of +/- 2 cm (+/- 0.8 inches) in the measurements provided. Bed frames are typically described by the size of the mattress they fit, but the actual bed frame might be larger due to design features. For example, a double bed frame (135 cm) will fit a UK standard double mattress (135 cm width x 190 cm length), but the bed frame itself can be bigger.
Always check the dimensions of bed frames before buying to ensure they fit perfectly in your bedroom space. This will help you avoid any surprises during delivery and guarantee there’s enough space for both the frame and mattress.
Standard UK Bed Sizes
In the UK, mattress sizes are standardised, but bed frames can vary in size based on their design and style. It’s a common mistake to assume the mattress size matches the frame size, so always check the exact dimensions. Many bed frames are slightly larger than the mattress they support due to their structure and design.
In the UK, the majority of beds and mattresses are produced with imperial dimensions, yet they are frequently advertised with their approximate metric counterparts.
Use our quick guide to understand bed size differences and choose the perfect mattress and frame for your space.
| Bed Size | Dimensions (Imperial) | Dimensions (Metric) | Suitable For | Ideal Room Size |
| Small Single | 2’6″ x 6’3″ | 75 x 190 cm | Younger children or smaller rooms | Compact bedrooms |
| Single | 3′ x 6’3″ | 90 x 190 cm | Children, teens, or guest rooms | Smaller bedrooms |
| Small Double | 4’ x 6’3” | 120 x 190 cm | Solo sleepers needing extra space | Moderate-sized rooms |
| Double | 4’6” x 6’3” | 135 x 190 cm | Couples or solo sleepers wanting more space | Standard bedrooms |
| King | 5′ x 6’6″ | 150 x 200 cm | Taller individuals or those needing more legroom | Larger bedrooms |
| Super King | 6′ x 6’6″ | 180 x 200 cm | Families or those valuing spacious sleeping areas | Spacious rooms |
Small Single Bed Size
Small single beds and mattresses are great for younger children or those with a smaller frame. The measurements are 75 cm wide and 190 cm long, which translates to roughly 2 feet 6 inches in width and 6 feet 3 inches in length when using imperial units. These beds are perfect for smaller rooms where space is limited and can also be a great first “big bed” for kids transitioning out of a cot.
Single Bed Size
Ideal for both children and adults, a single bed and mattress typically measure 90 cm in width and 190 cm in length, which is 3 feet wide and 6 feet 3 inches long in imperial measurements. Single beds are wider than small singles, offering ample space for one person. This size is commonly used for children’s beds, including bunk beds, and can accommodate growth spurts from toddlerhood through to the teenage years.
Small Double Bed Size
A small double bed and mattress measure 120cm in width and 190cm in length, which is equivalent to 4 feet wide and 6 feet 3 inches long. Often referred to as a ‘queen’ or ‘three-quarter’ bed, the small double is wider than a single but narrower than a standard double. It offers ample space for one person or can accommodate two, though it may feel a bit snug for two adults. This size is perfect for smaller bedrooms or guest rooms where a full double would be too large. Small sofas with storage options, such as ottoman or divan bases, are an excellent choice when space is limited.
Double Bed Size
A standard double bed and mattress measure 135 cm wide by 190 cm long, or 4 feet 6 inches wide by 6 feet 3 inches long in imperial measurements. It’s designed to comfortably fit two adults and is the most popular bed size in the UK, making it easy to find in any style. Double beds are perfect for small to medium-sized bedrooms, offering a good balance of comfort and space.
King Size Bed Dimensions
A king-size bed and mattress measure 150 cm wide by 200 cm long, or 5 feet wide by 6 feet 6 inches long in imperial measurements. It offers extra length compared to a standard double bed, making it a great choice for taller individuals or anyone who wants more space to stretch out.
Super King Size Bed Dimensions
A super king-size bed and mattress measure 180 cm wide by 200 cm long, or 6 feet wide by 6 feet 6 inches long in imperial measurements, making it the largest standard UK bed size. With plenty of room for two adults, it’s perfect for couples who enjoy extra space or families who love Sunday mornings cuddled up together—including pets! Ideal for large bedrooms, a super king bed offers unmatched comfort and luxury for those who value space while they sleep.

How to Measure a Bed for the Perfect Fit
When buying a new bed or mattress, it’s important to measure your space to ensure everything fits perfectly. Start by measuring the length and width of the bed. Use a tape measure from the headboard to the foot of the bed for length and from one side to the other for width. Next, check the size of your room to make sure there’s enough space around the bed for easy movement. Keep in mind that bed frames might be slightly wider and longer than the mattress, so check those dimensions too. Don’t forget to consider the need for bedside tables or under-bed storage.
Before you make your purchase, measure your doorways, stairways, and any corners your mattress or bed will need to pass through. Ensure doorways are wide enough to accommodate the mattress and that staircases or low ceilings won’t be an issue. When measuring for corners or turns, consider the mattress length and depth to make sure it will fit around tight spaces without bending. For extra peace of mind, try measuring diagonally to check clearances.
Taking these measurements will help avoid any delivery issues and ensure your bed fits comfortably in your home.
