Mattress Size Guide: A Complete Mattress Size Chart

A new mattress is the first real step toward sleeping better, but with so many options out there, working out bed sizes can get confusing fast.

Beyond picking the right type of mattress, getting the size right matters just as much, both for your own comfort and for making the most of your room. A mattress that's too small leaves you feeling cramped, while one that's too big can make the whole bedroom feel off.

This guide and chart walks you through the mattress sizes you'll come across here in Singapore, with their dimensions and a sense of which sleepers and rooms each one suits.

Regional Mattress Size Differences

Before we get into the specifics of each size sold in Singapore, it helps to know that bed sizes aren't standard everywhere; they shift quite a bit from region to region.

A 'king' in the United States, for instance, isn't quite the same size as a 'king' in the United Kingdom or Europe. Even within Asia there's some variation. Singapore tends to follow UK dimensions more closely, though you may still find small differences between manufacturers.

• Single: approximately 91 x 190 cm in Asia (30 x 75 inches in the US, 90 x 190 cm in the UK)
• Twin/Super Single: approximately 107 x 190 cm in Asia (38 x 75 inches in the US)
• Queen: approximately 152 x 190 cm in Asia (60 x 80 inches in the US, 135 x 190 cm in the UK, 140 x 200 cm in the EU)
• King: approximately 183 x 190 cm in Asia (76 x 80 inches in the US, 150 x 200 cm in the UK, 160 x 200 cm in the EU)
• California King: 72 x 84 inches in the US, not commonly listed in UK/EU/Asia charts
• Super King: 180 x 200 cm in the UK and EU

Keep this in mind especially when you're buying bed frames or bedding from overseas retailers. It's always worth double-checking the exact dimensions of your mattress before you commit, just to be sure everything fits.

What Size Is a Single Mattress?

A single mattress usually measures around 36 inches (91 cm) wide and 75 inches (190 cm) long.

It's the smallest of the standard adult sizes, and it suits children's rooms, smaller guest rooms, or anyone sleeping alone who doesn't need much room to stretch out.

What Size Is a Super Single Mattress?

A step up from the single, the super single mattress generally measures around 42 inches (107 cm) wide and 75 inches (190 cm) long.

That extra width gives solo sleepers a bit more room to move, which is why it's a common choice for teenagers moving up from a single bed, or for adult bedrooms where a double would feel too large. For anyone who shifts around a lot during sleep, that little bit of extra space can matter more than you'd expect.

What Size Is a Queen Mattress?

From here we move into sizes better suited to couples, or to anyone who simply likes more room to themselves. A queen mattress in Singapore measures around 60 inches (152 cm) wide and 75 inches (190 cm) long.

It's a popular, versatile size that gives two adults enough room to sleep comfortably without taking over an average bedroom. The queen strikes a fair balance between space and practicality, which is part of why it's such a common choice for couples and guest rooms alike.

What Size Is a King-Size Mattress?

For couples who really want their own space at night, a king-size mattress is worth considering. In Singapore, this usually measures around 72 inches (183 cm) wide and 75 inches (190 cm) long.

The extra width gives couples noticeably more room to spread out without disturbing each other through the night. If you're thinking about a king, just make sure your master bedroom can comfortably fit it alongside the rest of your bedroom furniture.

California King Mattress

The California King isn't as common in Singapore as the standard king, and it comes with a different set of proportions. It typically measures around 72 inches (183 cm) wide and 84 inches (213 cm) long.

It's narrower than a standard king, but longer, which makes it a good option for taller sleepers who find their feet hanging off the end of a regular king. If you're tall and share a bed, the extra length can make a real difference to how well you sleep.

Choosing the Best Mattress Size: Factors to Consider

With so many sizes to pick from, how do you land on the right one? A few things come into play.

Start with your room. A king-size mattress will likely overwhelm a small bedroom and make it feel tight. Measure carefully, and leave room for your other bedroom furniture and comfortable movement around the bed.

If you share your bed, think about your partner's size and how much personal space you both like. Taller sleepers in particular should pay attention to mattress length, so their whole body is properly supported.

Your own preferences and your budget will shape the final decision too. And don't forget: the bed frame you already have, or plan to buy, needs to match whichever mattress size you choose.
