Bed Size Guide: What Size Bed Will Fit Your Room?

By George 1 January 2026

Choosing the right bed size is one of the most important decisions when designing a comfortable and functional bedroom. With US sizes ranging from Twin all the way to Super Emperor, 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.

US 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 

Twin

39” x 75”

The standard one-person bed. This is ideal for children, pre-teens and single sleepers who are looking to maximise floor space. Fits well in small rooms, kids’ bedrooms and dorm rooms.

Twin XL

39” x 80”

Great for single adults are tall. Fits well in college dorms, adult bedrooms and guest rooms. 

Full

54” x 75”

Suitable for a single adult who wants some extra room, or couples who prefer a snug fit. This bed is good for adult bedrooms, guest rooms and smaller apartments.  

Full XL 

54” x 80”

For taller adults and suitable in small adult bedrooms or rooms where vertical space is the priority. 

Queen

60” x 80”

The most popular size for couples. Offers a great balance of sleeping space and room size compatibility. Fits in primary bedrooms and spacious guest rooms.

King

76” x 80”

Excellent for couples who want maximum personal space, or for co-sleeping with small children or pets. Fits well in large primary bedrooms and master suites.

California King 

72” x 84”

Designed for very tall sleepers. Slightly narrower than a Standard King but features an extra 4 inches of length. Fits well in long primary bedrooms or master suites 

Emperor

84” x 84”

A square-shaped bed offering great space for two. This is ideal for tall sleepers and is a true luxury upgrade. Suits very large primary bedrooms and grand master suites.

Super Emperor

90” x 84”

A true luxury size and one of the widest commercial beds available. Perfect for ultra-spacious, high-end layouts. Fits well in ultra-large master suites, or homes with integrated, open sleeping areas.

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 maneuver than traditional bed frames.

Even our largest beds 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 Full can work, but most couples prefer a Queen or a King for added comfort. If you want a hotel-style feel, Emperor 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 bedrooms. Low and Floating frames also help rooms feel more open.

What’s the difference between Emperor and Super Emperor?

An Emperor measures 84” x 84”, while a Super Emperor is 90” x 84”. The additional width creates a noticeably more expansive sleeping surface.

Do oversized beds need special bedding?

Yes, oversized beds such as Emperor do require specially sized bedding and mattresses. Many customers shop with specialist retailers that offer luxury or custom-size linens and mattresses.

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.
