Things you need to know about bed mattress sizes

What mattress sizes are available?
From smallest to largest, the four most common sizes of bed mattress are single, double, kingsize and super kingsize. There are some additional size choices for mattresses and bed frames, including small double, shorty and toddler.
Mattress size vs frame size
The size of a mattress and bed frame will always match; meaning a double mattress will fit on a double bed frame and so on. There’s no matching required with a divan bed, as it is a mattress and bed all-in-one.
Consider the bedroom layout and size

Measuring your space
Choosing the right bed size comes down to two key questions. First, will it fit comfortably in your room without crowding out wardrobes or other furniture, even if you’re tempted by the extra space a larger bed offers? Second, can you actually get it into the house, through the doorway, and up any stairs? Once you’ve checked both the room layout and the access route, finding the right bed and mattress becomes simple.
Small bedroom bed ideas
A single bed can create a clean, minimalist look in a tight room, while still offering plenty of comfort. Or you could pick a storage bed design to maximize every inch. It's perfect for stashing spare bedding, shoes, or anything you want out of sight.

FAQs about bed and mattress sizes
Is a queen size bigger than a king size bed?
A king size bed is larger than what many call a queen, offering more width and comfort. This makes the king size ideal for couples wanting extra sleeping space.
What are the bed sizes in the UK?
UK bed sizes follow a set of standard dimensions that cater to different room sizes and comfort needs.
- A small single measures 75 × 190 cm and works well in tight spaces or children’s rooms
- A single at 90 × 190 cm is the typical choice for one person.
- A small double (120 × 190 cm) offers extra width for solo sleepers.
- The double at 135 × 190 cm is a popular option for couples who don’t mind a cosy fit.
- For more space, a king size measures 150 × 200 cm, giving extra length and width.
- The super king, at 180 × 200 cm, provides the most generous sleeping area for larger bedrooms.
Are double and king size the same?
A double bed and a king size bed are not the same. A king size bed is wider and longer. It provides more space for couples or taller sleepers. Choosing between double vs king depends on your room size and your comfort preferences.
How to clean your bed and mattress?
To clean your mattress, vacuum it thoroughly, spot‑clean stains with mild detergent, and allow it to air out. Washing bedding weekly and rotating your mattress regularly helps maintain its freshness and extend its lifespan. A clean mattress improves sleep quality and overall hygiene.

What are some ways to recycle mattress?
You can recycle your mattress through local council collection, specialist recycling centres, or charity donation if it’s in good condition. Recycling your mattress helps reduce landfill waste and supports eco‑friendly disposal.
How do I know what bed is right for me?
Choosing the right bed means balancing comfort with practicality.
- Start with size, ensuring the bed fits in your room while giving you enough sleeping space.
- Consider the base type such as divan, ottoman, or slatted frames, which affects support and durability. Your preferred style also matters, whether you want a modern low‑profile frame or a classic upholstered headboard that complements your décor.
- Set a realistic budget that covers both the bed frame and mattress, and pay attention to materials, from solid wood and metal frames to breathable or hypoallergenic mattress fabrics.
- Finally, think about your storage needs. Beds with drawers or lift‑up ottoman bases are ideal for maximising space in smaller bedrooms.
Is it better to have a higher or lower bed?
Higher beds offer easier access and a more traditional look, while lower beds create a modern, minimalist feel. Your ideal height depends on mobility, style preference, and how much storage you need. Both high and low beds can provide excellent comfort with the right mattress.
How do I calculate my bed size?
Measure the length and width of your mattress or bed frame using a tape measure, then compare it to standard UK bed dimensions. Leave enough space around the bed for movement and furniture placement. Accurate measurements ensure you choose the correct mattress size and bedding.
How often should you replace your bed?
Most beds and mattresses should be replaced every 7–10 years, depending on wear and comfort. If you notice sagging, discomfort, or poor sleep, it may be time for an upgrade. Regular replacement ensures proper support and better sleep quality.
