In brief
- King size does not mean the same dimensions in every country.
- In UK stores, a 150×200 cm mattress may be called king size, while 180×200 cm may be called super king.
- A US king size mattress measures 76×80 inches, or approximately 193×203 cm.
- A 160×200 cm bed may be described as queen size and a 180×200 cm bed as king size. Always check the actual measurements before buying.
- Choose a Denora bed by the sleeping area stated in centimetres, not by the English size name.
- Before ordering, separately check the size of your chosen mattress and the full width and length of the bed frame.

Why do king size bed dimensions vary?
The same king size label can refer to different bed dimensions in different countries. The name alone is not enough, especially when you are buying the bed and mattress separately. Always compare their width and length in centimetres.
In UK furniture stores, a 150×200 cm mattress may be called king size, while a 180×200 cm mattress is called super king. The latter is 30 cm wider, although both have the same length.
In US stores, king size dimensions are given in inches: 76×80. This equals 193.04×203.2 cm. In the table, we round the size to 193×203 cm to make comparison easier.
| Country and size name | Mattress width × length | Key difference |
|---|---|---|
| United Kingdom: king size | 150×200 cm | 30 cm narrower than the super king listed here |
| United Kingdom: super king | 180×200 cm | A 180 cm wide sleeping area |
| United States: king size | 76×80 inches, approximately 193×203 cm | It is neither 180×200 nor 200×200 cm |
Retailers may use these size names differently. Check especially carefully when considering a non-standard or made-to-order bed.
Does a king size bed measure 180×200 cm?
King size usually suggests a large bed, but the name does not tell you its exact dimensions. Look for the width and length of the sleeping area in the product description.
If you want a 180×200 cm bed, choose by these measurements. If you want a bed that is 200 cm wide, look for a 200×200 cm size. These are different beds even if both are described as king size.
The same principle applies to the mattress. A 180×200 cm mattress needs a sleeping area of the same size. A US mattress measuring approximately 193×203 cm is not a substitute because it is both wider and longer.
What is the difference between queen size and king size?
Within one retailer's range, a king size bed is usually wider than a queen size bed. However, do not mix size systems from different countries. A US queen size and a UK king size can have a similar width.
In European furniture stores, you may see a 160×200 cm bed described as queen size and a 180×200 cm bed as king size. In that case, the king size is 20 cm wider. Both are 200 cm long.
In the United States, a queen size mattress measures 60×80 inches, or 152.4×203.2 cm. A king size measures 76×80 inches, or 193.04×203.2 cm. Therefore, a US queen size is not the same as a 160×200 cm bed.
| Where you are buying | Queen size | King size |
|---|---|---|
| Common sizes in European stores | 160×200 cm | 180×200 cm |
| United States | Approximately 152×203 cm | Approximately 193×203 cm |
If you need a 160×200 cm sleeping area, choose your Denora bed using this measurement. This allows you to select the right size without wondering which English label a retailer has assigned to it. The table is a useful guide, but you should still check the measurements of the selected bed before ordering.
Mattress dimensions and the complete bed frame
A 180×200 cm sleeping area does not mean that the complete piece of furniture is 180 cm wide and 200 cm long. Upholstered sides, a headboard and a footboard can increase the external dimensions. The exact difference depends on the model.
Check two things in the product description: the mattress size the bed is designed for and the amount of floor space occupied by the complete bed. If the external dimensions are not provided, ask for them before ordering.
Mark the full outline of the bed on your room plan. To check how much circulation space will remain, use the calculator in our guide to choosing bed width.
What should you check before ordering?
- Find the width and length of the sleeping area in centimetres in the product description.
- Compare them with the width and length of your chosen mattress.
- Separately note the greatest external width and length of the bed frame.
- Check the specifications of the selected option rather than relying on a photograph of a different size.
- If only king size is stated, ask for the exact measurements before paying.
One inch equals 2.54 cm. We have rounded the measurements in the table, but you should rely on the exact figures in the product description when buying.

Frequently asked questions
What are the dimensions of a king size bed?
They depend on the country and retailer. In UK stores, you may find a 150×200 cm king size, while the US size is 76×80 inches, or approximately 193×203 cm. The exact dimensions should be stated in the product description.
Does king size always mean 180×200 cm?
No. In UK stores, a 180×200 cm bed may be called super king, while a 150×200 cm bed is called king size. Naming conventions can differ in other countries.
Will a 200×200 cm mattress fit a 180×200 cm bed?
No. A 200×200 cm mattress is 20 cm too wide for that sleeping area. Choose a mattress in the size specified for the bed.

No. The bed sides and headboard can take up additional space. Check the full width and length of the frame in the description or drawing for the selected model.
