Mattress sizes by country differ more than the size names suggest. A "king" is 76 × 80 in (about 193 × 203 cm) in the United States and Canada, 150 × 200 cm in the UK, and 180 × 200 cm in many Gulf shops. Importers who order by name instead of centimetres end up with a mattress that does not fit the base. The reliable method is to buy by nominal width × length in centimetres and confirm the figure in writing.
This guide is written by ellda mobilya, a furniture manufacturer in Kayseri, Türkiye, producing sofa sets, corner sofas, bed base sets and mattresses since 2010. It compares the size systems of North America, the UK, the EU and the Gulf, and shows which of our catalogue bed base sizes line up with which market. Last verified: November 2026. No single official body publishes these sizes for every market, so the figures below come from retailer and standards pages and should be treated as nominal.
What is a nominal mattress size?
A nominal size is the rounded width × length used to name and sell a mattress, for example 160 × 200 cm. The real product is slightly smaller or larger because of cover thickness, edge construction and tolerance. In Europe, EN 1334 defines how the dimensions of mattresses, bed frames, divans and bed bases are measured and sets tolerances so that components fit each other. The standard describes measurement, it does not decide which sizes a market sells.
What are the mattress sizes in the US and Canada?
The two markets use the same inch-based system. Sources agree on the main sizes; small differences of an inch or so appear between brands, and the Canadian king is usually the same as the US standard king.
| Name | Inches | Approx. cm |
|---|---|---|
| Twin | 38 × 75 | 97 × 190 |
| Twin XL | 38 × 80 | 97 × 203 |
| Full | 54 × 75 | 137 × 190 |
| Queen | 60 × 80 | 152 × 203 |
| King | 76 × 80 | 193 × 203 |
| California king | 72 × 84 | 183 × 213 |
Sizes in inches are from retailer guides such as the Canadian bed size chart by Mattress Miracle and Amerisleep. Mattresses from Türkiye are under a US antidumping duty order, so we do not quote mattresses for the US; see our mattress manufacturer guide. For Canada, read the Canada import guide.
What are the mattress sizes in the UK?
UK sizes are metric but not round: widths of 75, 90, 120, 135, 150 and 180 cm with a length of 190 or 200 cm.
| Name | Width × length (cm) |
|---|---|
| Small single | 75 × 190 |
| Single | 90 × 190 |
| Small double | 120 × 190 |
| Double | 135 × 190 |
| King | 150 × 200 |
| Super king | 180 × 200 |
These are the figures most UK retailers publish, for example the Bed Kingdom size guide. Some listings give slightly different king and super king figures (for example 152 × 198 and 183 × 198 cm), so ask for the exact size of the specific model. UK mattresses and bed bases also fall under fire safety rules; see the UK fire safety guide and the UK import guide.
What are the mattress sizes in the EU?
Check country-specific retailer listings rather than treating Europe as one size system. For example, IKEA Germany lists 80 × 200, 90 × 200, 140 × 200, 160 × 200 and 180 × 200 cm mattresses. IKEA France also lists 90 × 190 and 140 × 190 cm options. These are examples from individual retailers, not an EU-wide size standard. Agree nominal width × length in centimetres and confirm the dimensions of the specific model before ordering.
What are the mattress sizes in the Gulf?
Gulf retailers mix European and UK naming. UAE retailer guides, such as the Kurlon UAE size guide, list a single of around 90 × 190 or 90 × 200 cm, a queen of about 150 × 200 cm and a king of about 180 × 200 cm. A European-brand "queen" can be 160 × 200 cm instead. We found no Saudi-specific size standard, so confirm with your own showrooms. In the Gulf, the name matters least: write the centimetres.
Which ellda sizes fit which market?
Our catalogue bed base sets are listed for mattresses of 160 × 200 cm, 180 × 200 cm and 90 × 200 cm. Compare them with the charts above:
| ellda size | Closest match | Fit note |
|---|---|---|
| 180 × 200 cm | UK super king; Gulf king | Same nominal size |
| 160 × 200 cm | 160 × 200 cm example sold by IKEA Germany and France; some Gulf "queen" | Differs from UK king (150) and US queen (152 × 203) |
| 90 × 200 cm | 90 × 200 cm example sold by IKEA Germany and France; Gulf single (90 × 200) | 10 cm longer than a UK single (190) |
Sizes outside this list, for example a UK king or a 140 × 200 cm base, are not in the catalogue. If you need one, ask in the enquiry; whether it is possible is confirmed in the quote. Mattress heights in the 2025 bedding catalogue run from 24 to 37 cm and the mattress size per model is also confirmed in the quote.
Checklist: what to write in a mattress size enquiry
- Width × length in cm for every line, not the size name
- Destination country, so the right size system is assumed
- Whether the mattress goes on a base from the same order (check the internal frame size, not only the outer size)
- Required height and surface per model
- The market fire or safety requirement, so it is confirmed in the quote
- Whether you need mixed pallets with bed bases or sofas in one shipment
How ellda handles mattress and base sizes
We produce bed base sets and mattresses in our 10,500 m² factory in Kayseri Organized Industrial Zone, with catalogues in English, Arabic and Turkish and a team that works in all three languages. Bases and mattresses can travel in one mixed load with sofas, and the loading plan is shared with the quote. Price, minimum quantities, lead time and shipping terms depend on model, size and destination and are stated in the quote.
For bases, read what a baza is. To start, add the sizes you need to the wholesale page enquiry, or use the export page for shipments abroad. Models are on the mattress and bed base pages.
