Mattress Size Chart: US vs UK vs EU Bed Dimensions Explained
Compare US, UK and EU mattress sizes with bed dimensions in inches and centimeters, naming differences and bedding fit tips.
Mattress size names can be misleading when shopping internationally. A king in one country may be closer to a queen in another. Before buying a mattress, bed frame or bedding, compare actual dimensions with the Mattress/Bed Size Converter.
US Mattress Sizes
US mattress sizes commonly include twin, twin XL, full, queen, king and California king. Queen is popular for couples and smaller master bedrooms, while king offers more sleeping width. Always check inches and centimeters if you are buying frames or sheets from outside the US.
UK and EU Mattress Sizes
UK sizes include single, small double, double, king and super king. EU sizes often use centimeter dimensions like 90x200, 140x200 or 180x200. The naming system is different, so comparing labels alone can lead to frame and bedding mismatches.
Do Not Forget Pillows and Bedding
Once you choose a mattress, match pillows and pillowcases separately with the Pillow Size Converter. Pillow sizes and bedding sets can also vary by region, especially European square pillows and king pillowcases.
