A good night’s sleep starts with choosing the right bed size. For many people in the UK, a double bed offers the perfect balance between space-saving and comfort. Whether you’re furnishing a guest room, outfitting a new home, or upgrading from a smaller size, understanding double bed size measurements is essential. This comprehensive guide will cover everything you need to know about double bed size measurements in inches, centimetres (cm), and feet, and how to choose the right bed for your space and sleeping needs.
What Are the Standard Double Bed Size Measurements in the UK?
In the UK, the standard double bed size refers to the size of the mattress, not including the frame. The standard dimensions are:
- 135 cm x 190 cm
- 54 inches x 75 inches
- 4 feet 6 inches x 6 feet 3 inches
These dimensions apply to the mattress itself. However, the bed frame may be slightly larger, depending on its design and materials. Always measure the outer frame if you’re working with limited room space.
Double Bed Frame Dimensions
While the mattress size is standardized, bed frame sizes can vary. The outer dimensions of a double bed frame typically add 2 to 5 inches (5 to 12 cm) on each side to accommodate design features like padded edges, built-in storage, or headboards and footboards.
Example:
- Mattress: 135 cm x 190 cm (4ft 6in x 6ft 3in)
- Frame: Up to 145 cm x 200 cm (4ft 9in x 6ft 7in), depending on style
Tip: Always allow extra space for the frame if you are planning your room layout.
Room Size Requirements for a Double Bed
A standard double bed is suitable for most average-sized UK bedrooms. The recommended minimum room size for a double bed is:
- 2.4m x 3m (240 cm x 300 cm)
- 7.9ft x 9.8ft
This space allows for walking room around the bed and space for furniture like bedside tables or wardrobes.
If you’re tight on space, consider a storage bed or wall-mounted furniture to maximize functionality.

|---|---|---|
| CM | 135 cm | 190 cm |
| Inches | 54 inches | 75 inches |

- Couples with smaller bedrooms
- Guest rooms where flexibility is needed

Double Bed vs Small Double Bed
Understanding the distinction between a standard double and a small double is crucial, especially for tight spaces. Comparison between Double vs queen size (small double) mattress.
Small Double Bed (a.k.a. Queen or Three-Quarter Size):
- 120 cm x 190 cm (47 inches x 75 inches / 4ft x 6ft 3in)
Standard Double Bed:
- 135 cm x 190 cm (54 inches x 75 inches / 4ft 6in x 6ft 3in)
Key Difference: A double bed gives an additional 15 cm (6 inches) of width, which can make a big difference for two sleepers.
Mattress Depth and Considerations
Besides length and width, depth plays a role in comfort and fit with bed sheets and protectors.
- Standard mattress depth: 20–30 cm (8–12 inches)
- Extra-deep mattresses: up to 40 cm (16 inches)
Make sure your fitted sheets are designed to accommodate your chosen depth. For thicker mattresses, deep-pocket sheets are recommended.
Bedding and Accessories: What Fits a Double Bed?
When shopping for bedding, it’s important to match the size to your mattress:
- Duvet size: 200 cm x 200 cm (79 inches x 79 inches)
- Fitted sheet: 135 cm x 190 cm (with added depth for thick mattresses)
- Flat sheet: 230 cm x 275 cm (90 inches x 108 inches)
- Mattress protector: Match mattress dimensions and thickness
Always double-check the packaging, as UK, EU, and US sizes can differ slightly.
Tips for Choosing the Right Double Bed
- Measure Your Room First
Ensure there’s enough clearance for walking space, storage, and other furniture. - Consider the Bed Frame Size
Don’t just measure the mattress space, account for decorative frames, footboards, or storage bases. - Think About Who Will Use It
If two people will be using the bed regularly, consider whether a double provides enough width or if a king might be more comfortable. - Plan for Storage
Opt for divan beds or ottoman-style bases if you need extra space in smaller bedrooms. - Check Access Points
Make sure the bed can fit through doorways and staircases when delivered!
