UK Bed Sizes Explained
-
Small Single (2FT6)
Best for children’s rooms, small bedrooms, or tight layouts where you need maximum floor space for toys, storage or furniture.
-
Single Bed (3FT)
Ideal for kids, teenagers, solo sleepers, or guest rooms. A popular choice for compact spaces and available in multiple storage options like ottoman or divan bases.
-
Small Double (4FT)
Great for teens, growing kids, or couples with limited space. This “three-quarter” size feels spacious without overwhelming a small bedroom.
-
Double Bed (4FT6)
One of the UK’s most popular bed sizes. Perfect for couples, offering a comfortable amount of sleeping space without requiring a large room.
-
King Size (5FT)
A luxurious upgrade ideal for taller individuals and couples who prefer extra room. With a 200cm length, it prevents the cramped feeling shorter beds can cause.
-
Super King (6FT)
The ultimate wide bed for large bedrooms. This size is perfect for families, co-sleeping, or anyone who wants maximum comfort and space.
How to Choose the Right Bed Size
Before ordering, consider the following:
-
Room Dimensions
Measure the room’s length, width and height. Don’t forget:
- Doorways
- Stairs
- Hallways
- Ceiling height
- Position of wardrobes, radiators and windows
-
Headboard & Frame Style
Some headboards (like wingback or floor-standing designs) add extra width or height. Bed frames with thick upholstery are often larger than the mattress size.
-
Storage Needs
Ottoman beds and divan drawers require extra clearance around the bed. Consider whether the room is wide enough for drawers to open fully.
-
Aesthetic & Layout
Always leave space for movement. A bed should complement the room—not overwhelm it. Extra items like rugs, ottoman benches, or bedside tables help complete the look while maintaining balance.
