Must-Know Single Bed Frame Dimensions for Every Buyer
What is a Single Bed Frame?
Basic definition
A single bed frame is a structure designed to support a single mattress. It typically includes a base, side rails, and sometimes a headboard and footboard.
Purpose and use
It raises the mattress off the floor, helps air flow better, and makes the bed more stable. Single frames are ideal for one person and commonly used in small bedrooms, guest rooms, or children's rooms.
Standard UK Single Bed Size
UK standard measurements
It's 90 cm wide and 190 cm long, which is the standard size for a single bed in the UK. That's roughly 3 feet wide by 6 feet 3 inches long.
Comparison with other UK sizes
Compared to other sizes:
1. A single is 90cm x 190cm.
2. A double is 135 cm x 190 cm.
3. A king is 150 cm x 200 cm. The single bed fits neatly in the middle, making it ideal for small spaces.

Single Bed Frame vs Mattress Size
Why frame and mattress sizes differ
The bed frame is usually a bit bigger than the mattress. That's because it needs space for structure and support, especially if it has built-in features like drawers or padding.
How to match them correctly
Always check both the frame and mattress dimensions before making a purchase. If you already own a mattress, choose a frame that fits its size. If not, buy them together to avoid gaps or an overhang.
Width of a Single Bed Frame
Typical width range
Most single bed frames are around 90cm wide. Some styles may be slightly wider due to padding or design.
What affects the width
Materials, side panels, and upholstery can add a few extra centimetres. Wooden frames, for example, with thick side rails, will be wider than metal frames.
Length of a Single Bed Frame
· Common length options
The standard length is 190cm. However, you can also find extended single frames, which are about 200cm. These are great for taller people.
· Length for taller users
If you're over 6 feet, a long single bed offers more legroom. It offers the comfort of a single bed but feels less cramped.
Height from Floor to Top
Standard height guide
Most bed frames sit between 35 cm and 45 cm high from the floor to the top of the base. Add mattress height, and it could reach around 55cm to 65cm.
Pros and cons of different heights
Lower beds give a modern look and are easy to climb into. Higher beds allow for storage underneath and can be easier on your knees when standing up.
Clearance Under the Frame
· Under-bed space guide
Look for 25cm to 30cm of space under most standard-height frames. This is enough for storage boxes or baskets.
· Uses for under-bed clearance
Use it to store bedding, shoes, or seasonal clothes. It helps declutter your room without needing extra furniture.
Headboard Height Options
Average headboard height
Headboards range from 90 cm to 140 cm. Shorter ones are more minimal. Taller ones give a grander look.
Tall vs low headboards
Tall headboards make a style statement. Low headboards are more suitable for smaller rooms or those with sloped ceilings.
Small Single vs Standard Single
Key size differences
A small single bed is 75 cm wide, while a standard single bed is 90 cm wide. Both are the same length: 190cm.
Best use for each size
Small singles are ideal for very tight spaces, bunk beds, or young children. Standard singles are better for teens, adults, or growing kids.
Compact Single Bed Dimensions
Narrower frame sizes
Some compact single beds are even slimmer than small singles, explicitly designed for tiny box rooms or studio flats.
Ideal spaces for compact frames
Perfect for under-stair nooks, loft rooms, or as a daybed in a small guest space.

Single Bed Frame for Adults
Is it suitable for adults?
Yes, many adults comfortably sleep on a single bed, especially if they are of average height and sleeping alone.
Adult-friendly dimensions
Go for a standard or extended single if you're taller than average. Add a supportive mattress and headboard for complete comfort.
Single Bed Frame for Children
· Best frame size for kids
Start with a small single for younger children. As they grow, consider moving up to a standard single for more space.
· Safety and comfort tips
Choose a frame with rounded edges and low height. Avoid sharp metal corners and look for sturdy slats.
Single Bed Frame for Teenagers
Teen-friendly dimensions
Most teens will be happy with a standard single. If they're tall, go for an extended single version.
Room layout ideas
Add shelves, a desk, or a wardrobe nearby to keep everything accessible. A frame with storage drawers is a great space-saver.
Ideal Room Size for a Single Bed
Minimum space needed
You need at least 2 metres by 2.5 metres to fit a single bed comfortably. This allows for movement and the placement of other furniture.
Layout tips for small rooms
Place the bed in a corner or along the wall—Utilise vertical storage options, such as tall wardrobes or floating shelves.
Best Frame Sizes for Small Rooms
· Slimline options
Look for metal or open-frame beds with thin edges. These feel lighter in tight spaces.
· Choosing for tight spaces
Avoid bulky designs. Opt for frames with legs instead of boxed-in bases, as they create a more spacious and airy feel in the room.

Bed Frame Sizes for Guest Rooms
Ideal dimensions for spare rooms
A standard single works well in most guest rooms. It leaves enough space for a side table or chair.
Flexible sizing options
Use a trundle bed or daybed for multi-purpose rooms. These provide extra sleeping space without requiring an additional bed.
Measuring a Single Bed Frame
What to measure
Check the frame's width, length, and height using a measuring tape to ensure accurate measurements. Don't forget the space for the headboard and footboard.
How to measure correctly
Use a tape measure and note each point. Double-check against your room measurements to ensure a good fit.
Common Mistakes to Avoid
Overlooking frame width
Many buyers forget that frame width includes side panels. This can throw off your room plan.
Forgetting headboard space
Headboards can add 10cm to 20cm to the total length. Factor this in before placing it against a wall.
Tips for Measuring Your Space
Simple measuring steps
Start with the floor. Mark the bed area with tape. Then measure wall to wall, including skirting boards.
Tools you'll need
You'll need a tape measure, masking tape, a pencil, and paper. A laser measure is helpful for larger rooms.
How to Choose the Right Size
Consider user height
If the sleeper is tall, choose a longer frame. For shorter adults or kids, standard size is fine.
Consider room layout
Think about where doors, windows, and other furniture sit. Ensure the bed doesn't obstruct movement.
Single Bed Frame Sizes with Storage
Standard sizes with drawers
These frames stay close to standard single dimensions but include side or foot-end drawers.
How storage affects dimensions
