Detailed Guide to Each UK Bed Size
Small Single Beds (75cm x 190cm)
Perfect for children’s bedrooms, box rooms, or where space is extremely limited. While compact, they still provide comfortable sleeping for children up to teenage years. Consider upgrading when your child reaches 5’6″ in height for optimal comfort.
Ideal for: Children aged 3-16, very small guest rooms, bunk beds Not recommended for: Adults over 5’6″, restless sleepers
Single Beds (90cm x 190cm)
The most popular choice for teenagers and single adults in smaller bedrooms. Offers 15cm more width than small single, providing better comfort without taking up significant additional floor space. For more information read our Single Bed Buying Guide.
Ideal for: Teenagers, single adults, guest bedrooms, student accommodation Consider upgrading if: You’re over 6’2″ tall or prefer more sleeping space.
For a closer look at this size, head over to our Single Beds Buying Guide with tips on comfort, space, and choosing the right fit.
Small Double Beds (120cm x 190cm)
Often called “three-quarter beds,” these provide single sleepers with luxurious space while fitting into smaller bedrooms where a full double wouldn’t work comfortably. For more information read our Small Double Bed Buying Guide.
Ideal for: Single adults wanting extra space, smaller master bedrooms, tall teenagers Consider carefully: Two adults will find this size cramped for regular use.

Double Beds (135cm x 190cm)
The traditional UK double offers 67.5cm per person – adequate for many couples, especially in older properties with smaller bedrooms. However, modern sleep research suggests this may be insufficient for optimal sleep quality. For more information read our Double Bed Buying Guide
Ideal for: Couples in smaller bedrooms, guest rooms for couples Worth noting: Each person gets less space than in a single bed
King Size Beds (150cm x 200cm)
Currently the most popular choice for UK couples. Provides 75cm per person plus extra length (200cm vs 190cm). The additional 10cm length makes a significant difference for taller sleepers. For more information read our King Size Bed Buying Guide.
Ideal for: Most couples, master bedrooms, anyone over 6’0″ tall Room requirement: Ensure your bedroom is at least 2.7m x 2.8m
Super King Beds (180cm x 200cm)
Offers luxury hotel-level space with 90cm per person. Increasingly popular as bedroom sizes in new UK homes have grown. Perfect for couples who value undisturbed sleep. For more information read our Super King Size Bed Buying Guide.
Ideal for: Couples wanting maximum comfort, families who co-sleep, luxury bedrooms Consider carefully: Requires significant bedroom space and higher bedding costs
Emperor Beds (200cm x 200cm)
The ultimate in sleep luxury – essentially two single beds side by side. Provides 100cm per person, allowing complete freedom of movement without disturbing your partner. For more information read our Emperor Bed Buying Guide.
Ideal for: Very large master bedrooms, those with specific sleep needs, ultimate luxury Important note: Bedding can be expensive and harder to source
How to Choose the Right Size:
Measure Your Room Accurately
- Measure length, width, and height
- Note door and window positions
- Account for radiators, built-in wardrobes, and other fixtures
- Use our minimum room size guide above
Consider Your Sleep Habits
- Restless sleeper? Go larger than you think you need
- Share with a partner? King size minimum recommended
- Children or pets join you? Consider super king
- Tall (over 6’0″)? Ensure 200cm length minimum
Think About Future Needs
- Moving house plans in next 5 years?
- Relationship status changes?
- Children growing up?
- Health considerations requiring more space?
Budget Considerations
Remember that larger beds require:
- More expensive bed frames
- Costlier mattresses
- Higher-priced bedding
- Potentially more bedroom furniture
Common UK Bed Size Mistakes to Avoid
- Assuming bigger is always better – An oversized bed can make a room feel cramped
- Not measuring doorways – Ensure your chosen bed can actually get into the room
- Forgetting about bedding costs – Larger sizes mean ongoing higher costs
- Ignoring ceiling height – Low ceilings can make large beds feel overwhelming
- Not considering bed frame styles – Ottoman beds need extra clearance above for opening
Ottoman Beds: Special Size Considerations
Ottoman beds (storage beds with lift-up mechanisms) require additional planning:
- Height clearance: Ensure 60cm minimum from mattress to ceiling
- Access space: Allow extra room for the mattress to lift fully
- Weight considerations: Larger sizes with storage can be significantly heavier
UK vs International Bed Sizes: Standard, European & Non-Standard
Choosing the right mattress size is crucial, especially when buying from abroad. UK bed sizes differ from US and European standards, and some European beds are slightly wider or longer than UK equivalents. Always check dimensions to ensure a perfect fit for your bedroom.
Top Tip: Always compare mattress dimensions before purchasing imported bedding or furniture.
Standard UK vs International Sizes
| UK Bed Type | Width (cm) | US Equivalent | EU Equivalent | Notes |
|---|---|---|---|---|
| Single | 90 | Twin (99cm) | Single (90cm) | Standard single bed |
| Small Double | 120 | Full/Double (137cm) | Small Double (120cm) | Compact double for smaller rooms |
| Double | 135 | Full/Double (137cm) | Double (140cm) | Standard double |
| Queen | 160 | Queen (152cm) | Queen (160cm) | Popular international size |
| King | 150 | Queen (152cm) | King (160cm) | Minimum for couples in the UK |
| Super King | 180 | King (193cm) | Super King (180cm) | Optimal for most couples |
