90x150cm in Inches: Exact Size & Bedding Guide

90x150cm is approximately 35.4 x 59.1 inches. This size is most commonly a European single bed mattress or a large blanket/throw, and it is not a standard US mattress size. If you are buying bedding or a mattress topper, this measurement is close to a US “twin” (38×75 inches) but shorter and slightly narrower.

How the Conversion Works

To convert centimeters to inches, you divide by 2.54 (since 1 inch = 2.54 cm). For 90x150cm:

• 90 cm ÷ 2.54 = 35.43 inches (about 35.4″)
• 150 cm ÷ 2.54 = 59.06 inches (about 59.1″)

So the exact conversion is 35.43 x 59.06 inches. Most people round to 35.4 x 59.1 or simply say “about 35 x 59 inches.” If you see a label that says “90×150 cm,” it is the same as a metric “single” bed size used in many European and Asian countries.

What Fits a 90x150cm Mattress?

This size is a common European single bed (sometimes called a “small single” or “cot size” in some regions). It is narrower than a standard US twin (38×75 inches) and much shorter. Here is how it compares to US sizes:

Bed Size	Dimensions (inches)	Dimensions (cm)
90×150 cm	35.4 x 59.1	90 x 150
US Twin	38 x 75	96.5 x 190.5
US Twin XL	38 x 80	96.5 x 203
UK Single	36 x 75	91.4 x 190.5

Because the 90x150cm bed is shorter than a standard US twin, a US twin fitted sheet (38×75) will be too long and may bunch up. A UK single fitted sheet (36×75) is also too long. You will likely need to buy sheets labeled “90×150” or “European single” to get a proper fit. Alternatively, you can use a flat sheet and tuck it securely.

Is 90x150cm a Standard Size?

Yes, it is a standard size in many countries, but not in the US. In Europe, it is often called a “single bed” (e.g., in Germany, France, Spain). In Japan, it is a common “single” size. In the US, the closest standard is a “twin,” but the 90x150cm is significantly shorter. If you are traveling or moving, check the country’s standard sizes. For example, a UK single is 36×75 inches (91×190 cm), which is longer but slightly wider. A US twin is 38×75 inches (96×190 cm). The 90x150cm is a “short single” – often used for children’s beds, guest rooms, or in some hotels.

Common Confusion: 90×200 vs 90×150

A frequent mix-up is between 90x150cm and 90x200cm. The 90x200cm is the standard European single bed size (about 35.4 x 78.7 inches). The 90x150cm is 50 cm (about 20 inches) shorter. If you buy a fitted sheet for a 90x200cm bed, it will not fit a 90x150cm mattress – it will be too long. Always measure your mattress before buying bedding. A 90x150cm mattress is sometimes used for a crib (though cribs are usually smaller) or a daybed.

How to Choose Bedding for 90x150cm

When shopping for sheets, duvets, or mattress protectors:

• Look for labels that say “90×150” or “European single” – these are your safest bet.
• If you cannot find a fitted sheet, buy a flat sheet and use a mattress clip or tuck it tightly under the mattress.
• For a duvet, a 90x150cm mattress usually pairs with a duvet that is about 135x200cm (or 155x220cm for more coverage). Check the duvet cover size separately – it is not the same as the mattress size.
• If you are using a mattress topper, make sure it matches the exact dimensions – a 90×200 topper will overhang and may not stay in place.

Converting Other Common Sizes

If you are comparing sizes, here are a few quick conversions:

• 90×200 cm = 35.4 x 78.7 inches (standard European single)
• 80×200 cm = 31.5 x 78.7 inches (small single)
• 120×200 cm = 47.2 x 78.7 inches (double/queen in some countries)
• 140×200 cm = 55.1 x 78.7 inches (double)

To convert any cm measurement to inches, divide by 2.54. For example, 200 cm ÷ 2.54 = 78.74 inches.

Frequently Asked Questions

Is 90x150cm a twin or full? It is smaller than a US twin. A US twin is 38×75 inches (96×190 cm). The 90x150cm is 35.4×59.1 inches – shorter and slightly narrower. It is not a full (double) size.

What size sheets fit a 90x150cm mattress? You need sheets specifically labeled “90×150” or “European single.” A US twin fitted sheet will be too long and too wide (though width is only slightly off, the length is a bigger issue). A UK single (36×75) is also too long.

What is 90x150cm in feet? 90 cm is about 2.95 feet, and 150 cm is about 4.92 feet. So the mattress is roughly 3 feet by 5 feet.

Can I use a 90x200cm duvet on a 90x150cm bed? Yes, you can use a longer duvet – it will just hang over the end of the bed. Many people use a 135x200cm or 155x220cm duvet for a 90x150cm bed for extra coverage. Just make sure the duvet cover fits the duvet, not the mattress.

Is 90x150cm a crib size? It is larger than a standard crib mattress (typically 28×52 inches or 71×132 cm). A 90x150cm is more like a small single bed for a child or a guest bed, not a crib.

What if my mattress is 90x150cm but I bought a US twin sheet? The sheet will be too long (75 inches vs 59 inches) and may gather under the mattress. You can try tucking the excess under the mattress, but it may not stay smooth. Better to buy a fitted sheet made for 90x150cm.
