Single bed sizes: a guide to standard dimensions and practical advice

Thinking of buying a single bed? Knowing the exact standard dimensions is essential to ensure comfort, functionality, and a perfect fit for mattresses, bed bases, and bed linen.

We understand that in smaller spaces or children’s bedrooms, every centimetre counts and every decision matters.

In this article, we will guide you through the most common single bed sizes and help you choose the bed and mattress that best suits your needs.

What are the standard sizes of a single bed?

In the UK, the standard sizes of a single bed are as follows:

🛏️ 80 x 190 cm

🛏️ 80 x 200 cm (long version)

🛏️ 90 x 190 cm

🛏️ 90 x 200 cm

These measurements refer to the mattress and bed base; the bed frame (including the headboard and footboard) may be slightly larger.

The 90 x 200 cm version is currently the most popular because it provides a few extra centimetres in length, making it more comfortable for taller adults or teenagers.

Compact, maxi or custom-made single bed?

In addition to the standard sizes, a few other options are available:

• Compact single bed (80×190 cm): ideal for small spaces such as guest rooms, small bedrooms, and bunk beds.

• The maxi single bed (100×200 cm) is perfect for those who want more freedom of movement without switching to a queen-size bed.

• A custom single bed is an ideal choice for specific needs, such as storage beds, space-saving furniture or customised structures.

What to look for when choosing the size of a single bed

When choosing the size of a single bed, we recommend considering these three factors:

1. Available space in the room

Accurately measure the available space, taking into account any bedside tables, furniture, and door and window openings. Leave at least 60 cm of free space on one side of the bed.

2. Height of the person who will be using it

For optimal comfort, the mattress should be at least 10–15 cm longer than the person. If the person is very tall, a 200 cm mattress is preferable.

3. The age and sleeping habits of the person who will be using the bed

• For children and teenagers, smaller sizes (80×190 cm) may be sufficient.

• For adults or tall teenagers, a larger size (90×200 cm or 100×200 cm) is better.

• Those who move around a lot in their sleep may find that a larger surface area improves the quality of their rest.

How to choose the right mattress for a single bed

Once you have decided on the size of the bed, it is time to choose a suitable mattress in terms of size, comfort, and support. Here are some tips:

• Always check that the bed base and mattress are the same size (e.g. a 90×200 cm bed base requires a 90×200 cm mattress).

• Choose your mattress based on your sleeping position and body weight — an ergonomic, breathable mattress can make all the difference, especially if it is used daily.

• Also consider the mattress’s height: for single beds, we recommend thicknesses between 18 and 25 cm to ensure good support.

Don’t overlook these accessories for optimal rest

To complete your single bed and improve comfort, there are several accessories available:

• Slatted bed base: preferably with flexible wooden slats for optimal support.

• Ergonomic pillow: choosing the right pillow for your sleeping position can improve sleep quality.

• A breathable mattress cover is useful for maintaining hygiene and extending the life of the mattress.

• Custom-made bed linen: sheets and mattress covers should fit the mattress perfectly to prevent creasing.
