UK mattress size chart
UK mattress sizes use familiar names such as Single, Double and King, but their dimensions are different from similarly named US mattresses.
| Mattress size | Dimensions (cm) | Approx. dimensions (inches) |
|---|---|---|
| Small Single | 75 × 190 cm | 29.5 × 74.8 in |
| Single | 90 × 190 cm | 35.4 × 74.8 in |
| Small Double | 120 × 190 cm | 47.2 × 74.8 in |
| Double | 135 × 190 cm | 53.1 × 74.8 in |

European mattress size chart
European mattresses are commonly described directly by their width and length in centimeters rather than relying on one universal set of names.
| Common size | Dimensions (cm) | Approx. dimensions (inches) |
|---|---|---|
| Single | 90 × 200 cm | 35.4 × 78.7 in |
| Wide Single | 100 × 200 cm | 39.4 × 78.7 in |
| Small Double | 120 × 200 cm | 47.2 × 78.7 in |
| Double | 140 × 200 cm | 55.1 × 78.7 in |
| Large Double | 160 × 200 cm | 63.0 × 78.7 in |
| King / Large Double | 180 × 200 cm | 70.9 × 78.7 in |
| Extra Large | 200 × 200 cm | 78.7 × 78.7 in |
Names for metric mattress sizes are not standardized across Europe. Dimensions in centimeters are a more reliable way to compare European mattresses.
US vs UK vs European mattress sizes
Mattress names cannot always be converted directly between countries. The closest equivalent may still differ in width or length.
| US | US dimensions | UK / EU comparison |
|---|---|---|
| Twin | 96.5 × 190.5 cm | Close to UK Single / EU 90 × 200 |
| Twin XL | 96.5 × 203.2 cm | Close to EU 100 × 200 |
| Full | 137.2 × 190.5 cm | Close to UK Double / EU 140 × 200 |
| Queen | 152.4 × 203.2 cm | Close to UK King / EU 160 × 200 |
| King | 193 × 203.2 cm | Wider than UK Super King / EU 180 × 200 |
These are comparisons, not exact equivalents. Always compare the actual width and length before buying a mattress, bed frame, fitted sheet or other size-dependent product.
Common mattress sizes in centimeters
If a mattress is listed only by its dimensions, this quick chart shows how common metric widths compare.
| Mattress dimensions | Width | Length | Typical use |
|---|---|---|---|
| 90 × 200 cm | 90 cm | 200 cm | One person |
| 120 × 200 cm | 120 cm | 200 cm | Wide single / compact double |
| 140 × 200 cm | 140 cm | 200 cm | Double |
| 150 × 200 cm | 150 cm | 200 cm | Large double |
| 160 × 200 cm | 160 cm | 200 cm | Large double / two people |
| 180 × 200 cm | 180 cm | 200 cm | Large bed for two people |
| 200 × 200 cm | 200 cm | 200 cm | Extra-large bed |
Queen vs King mattress size
In the United States, a standard Queen mattress measures 60 × 80 inches (152.4 × 203.2 cm), while a standard King measures 76 × 80 inches (193 × 203.2 cm).
Both have the same standard length, but a US King is 16 inches (40.6 cm) wider than a Queen.
The terms Queen and King should not be assumed to have these dimensions outside the US. Other countries use different mattress standards.
King vs California King
A standard US King mattress measures 76 × 80 inches, while a California King measures 72 × 84 inches.
The standard King is wider, while the California King is narrower but four inches longer.
A California King can therefore provide extra length for taller sleepers, while a standard King provides more total width.
What mattress size should you choose?
Start with the number of people using the mattress, the height of the sleepers and the available space in the room.
For one person
A Single, Twin or similar mattress can be sufficient for one person. Taller sleepers may prefer a longer mattress such as a Twin XL or a 200 cm European size.
For two people
Wider mattresses give each sleeper more personal space. Double, Queen, King and larger metric sizes are commonly used by couples, but their actual dimensions differ between countries.
Check your room
Measure the available floor space before choosing a mattress. Remember to allow space for the bed frame, bedside furniture and comfortable movement around the bed.
Mattress size vs bed frame size
Mattress dimensions describe the mattress itself. The total dimensions of a bed frame are usually larger because the frame extends beyond the mattress.
A bed labeled for a particular mattress size should normally be designed to hold that size, but always check the manufacturer’s internal frame dimensions before combining products from different brands or countries.
This is particularly important when mixing US, UK and European products because similarly named sizes may have different measurements.

Are US and UK King mattresses the same size?
No. A US King is approximately 193 × 203 cm, while a standard UK King is 150 × 200 cm. Despite sharing the name King, they are substantially different in width.
Is a US Queen the same as a UK King?
They are similar but not identical. A US Queen is approximately 152.4 × 203.2 cm, while a UK King is commonly 150 × 200 cm.
Is a Full mattress the same as a Double?
In the US, Full and Double commonly refer to the same nominal 54 × 75 inch mattress. A UK Double, however, has different dimensions, so the term Double is not internationally interchangeable.
What is the difference between a Queen and King mattress?
In US sizing, both are normally 80 inches long, but a Queen is 60 inches wide and a King is 76 inches wide. A King therefore provides 16 additional inches of width.
Why do mattress sizes differ between countries?
Mattress standards developed separately in different markets. Countries use different measurement systems, traditional dimensions and naming conventions, so the same mattress name does not necessarily mean the same size.
Should I compare mattress names or dimensions?
Compare the actual width and length whenever possible. Dimensions provide a more reliable comparison than names such as Double, Queen or King because those names can mean different sizes in different countries.
