Small double vs double bed: What is the difference?

double

A small double bed bridges the gap between singles and doubles, offering versatility few other sizes can match. At 120cm wide, it’s perfect for teenagers transitioning from single beds, couples in compact apartments, and guest rooms where space is precious. 

While 15cm narrower than a standard double, these beds cost less, take up less space, and still provide ample room for most sleepers. Let’s explore whether this smart space-saving solution could work in your home.

Size differences

A small double (also called a queen) measures 120cm x 190cm, while a standard double spans 135cm x 190cm. 

Those extra 15 centimetres make a significant difference when sharing the bed, giving each person 67.5cm of space to stretch out on compared to 60cm on a small double.

Value for money

Small double mattresses and bedding cost around 10% less than standard doubles. While saving £50-100 on quality options might tempt you, base your decision on comfort and space requirements rather than price alone. Remember — you’ll spend a third of your life in bed, making comfort worth the investment.

Suitability for couples

A standard double bed remains the UK’s most popular choice for couples. They provide enough room for comfortable sleeping without dominating average-sized bedrooms. 

The extra width allows natural movement during sleep and reduces partner disturbance. However, smaller-framed couples who sleep close together often find small doubles perfectly comfortable, especially in modern apartments where space is premium.

Perfect for growing kids

Small doubles offer an excellent upgrade from single beds for teenagers or older children. They provide significantly more space than a single while using less room than a standard double, leaving more floor space for study areas and storage. 

This size proves particularly valuable through the teenage years and transitions seamlessly to university accommodation.

Room functionality

A small double bed work brilliantly in compact rooms where every centimetre counts, leaving more space for bedside tables and walking around. They’re ideal for spare rooms or master bedrooms in modern apartments. Standard doubles suit average-sized bedrooms better, offering that extra wiggle room without overwhelming the space.

Guest bedrooms

Small doubles shine in guest rooms where space often plays second fiddle to other home priorities. While a standard double might leave guests more room to spread out, a small double provides plenty of comfort for short stays.

You’ll save money on bedding, too, which is helpful when kitting out a room that sees occasional use. Plus, the compact size leaves space for a desk or storage, letting your guest room double as a home office or hobby space when guests aren’t in.
