What Size is a 5ft King Size Mattress?
A 5'0 king size mattress in the UK measures 150cm x 200cm (5 feet wide by 6 feet 6 inches long). That extra width and length compared to a standard double makes it an ideal upgrade for couples who want more personal space or anyone who seeking that extra comfort while sleeping.
The UK king mattress size is a favourite in master bedrooms and larger sleeping spaces, offering generous surface area without stepping into superking territory. It’s also a great choice for taller individuals, thanks to the additional 10cm in length compared to all other standard UK sizes. Want to compare all dimensions? Head to our Mattress Size Guide for a clear breakdown.
Who is a King Size Mattress Best For?
The 5ft mattress is the go-to for:
- Couples who want extra space or to reduce sleep disturbance from partner movement
- Taller individuals who may be needing extra legroom
- Master Bedrooms where space isn’t an issue
- Comfort Seekers wanting the most from their sleep space
- Families with kids or pets who occasionally like to share the bed
If you’ve ever felt cramped on a double or small double mattress, a king size mattress UK might be the game-changer your sleep needs.
