By George 2 January 2026

Choosing the right bed size is one of the most important decisions when designing a comfortable and functional bedroom. With UK sizes ranging from Small Single all the way to Super Caesar, it’s easy to feel unsure about which one will actually fit your space. Room size, layout, how you use the bedroom, and even how your staircase is shaped all play a role. This guide brings everything together so you can confidently choose the perfect size.

UK Bed Sizes Explained

To help you compare the different options at a glance, here is a clear table explaining each bed size, who it suits and the type of room it’s commonly used in:

Bed Size 

Dimensions 

Who It’s For 

Small Single

2’6” x 6’3”

This is the narrowest UK bed size. It is ideal for kids, box rooms, and student accommodation where space is limited.

Single 

3’0” x 6’3”

The standard one person bed. Great for teens, guest rooms and small studio flats.

Small Double 

4’0” x 6’3”

Sometimes called a “wide single”. Perfect for one person who wants extra room without filling the whole space. Works well in box rooms and young adult bedrooms 

Double 

4’6” x 6’3”

The classic UK double. Suitable for couples who don’t mind a tighter width, or for most standard master and guest rooms. 

King 

5’0” x 6’6”

A popular upgrade for couples who want more space. The extra 6 inches of length helps taller sleepers. This works well in main bedrooms

Super King

6’0” x 6’0”

This is the widest standard UK size. It is great for couples, families with pets or anyone who prefers a luxurious sleeping space. Best for large primary bedrooms. 

Emperor

6’6” x 6’6”

A generous, square shaped bed offering exceptional space for two. Ideal for tall sleepers and large master suites. 

Super Emperor

7’0” x 7’0”

A true luxury size. Perfect for very large bedrooms, boutique-style layouts and homes with integrated sleeping areas.

Caesar

8’0” x 7’2”

One of the widest commercial beds available. Designed for families who co-sleep or people wanting a hotel-level experience.

Super Casar 

8’10” x 7’2”

Almost 3 metres wide. Suited to ultra-large master suites, high-end homes and spacious, modern interiors.

This list contains the most common UK bed sizes but at Get Laid Beds we offer other sizes such as Petite Double, Small Super King, and Eastern King. These dimensions provide a great starting point, but choosing the right size is also about how you want your space to feel.

Choosing a Bed Size That Works With Your Space

Your bedroom size is the biggest deciding factor, but your personal preferences are just as important. Some people love the feel of a large, luxurious bed even if it means slightly less floor space, while others prefer a more open layout.

As a general rule, leaving around 60–70 cm of walk-around space at the sides and foot of the bed helps keep the room comfortable and functional. If your room is on the smaller side but you still want a larger bed, Low and Floating frame styles can visually open the space by sitting closer to the floor and allowing more light to flow around them.

Will the Bed Fit Up the Stairs?

This is one of the most common worries customers have, especially in older homes with narrow staircases or awkward turns. The good news is that all Get Laid Beds frames are delivered flat-packed, with the side rails, slats and headboards arriving as separate pieces. This makes them far easier to manoeuvre than traditional bed frames.

Even our largest beds, including Emperor, Caesar and Super Caesar, are shipped in long, slim components that can be angled and rotated through tight spaces. In most cases, if you can comfortably walk up your stairs, your bed can too.

What to Measure Before Ordering

A few simple measurements can help prevent issues on delivery day. Start with the narrowest point on your staircase, then check ceiling height if your stairs have turns as the longer rails need enough room to tilt. Measure any tight hallway areas leading to the bedroom, followed by the width and height of your door frames.

Once you’ve taken these measurements, compare them with the length of the longest rail on the bed size you’re considering. This quick check gives complete peace of mind.

Frequently Asked Questions

What’s the best bed size for couples?

A Double can work, but most couples prefer a King or Super King for added comfort. If you want a hotel-style feel, Emperor and Caesar beds provide significantly more room.

Will a King size make my room feel small?

Not necessarily. As long as you leave enough walk-around space, a King can work beautifully in many UK bedrooms. Low and Floating frames also help rooms feel more open.

What’s the difference between Emperor and Super Emperor?

An Emperor measures 200 x 200 cm, while a Super Emperor is 215 x 215 cm. The additional width and length create a noticeably more expansive sleeping surface.

Do oversized beds need special bedding?

Yes, oversized beds such as Emperor, Caesar and Super Caesar require specially sized bedding and mattresses. While we don’t offer oversized bedding, we do provide mattresses in all of our oversized sizes so your bed has the perfect, comfortable fit. For bedding, many customers shop with specialist retailers that offer luxury or custom-size linens.

How do I measure my staircase?

Measure the narrowest stair width, check ceiling clearance on any turns, and note the width of hallways and door frames. Because our beds arrive in slim, modular sections, they’re usually very easy to move.
