Mexican Mattress Sizes vs US, Canada and UK Sizes

By The SIMPLE team · Updated 2026-10-01

Mexican mattress names sound familiar, but they don't match US sizes. A Mexican Matrimonial is about a US Full, a Mexican Queen is a little narrower and 13 cm (5 in) shorter than a US Queen, and a Mexican King is wider and shorter than a US King. Whatever you buy in Mexico, go by the centimeters, not the name.

Mexican sizes vs US, Canada and UK

These are SIMPLE's four sizes, which follow the common Mexican names. Width × length. All four are 190 cm (74.8 in) long.

Mexican size	SIMPLE (cm)	Inches	Closest US / Canada	Closest UK
Individual	100 × 190 cm	39.4 × 74.8 in	Twin, 38 × 75 in	Single, 3 ft
Matrimonial	135 × 190 cm	53.1 × 74.8 in	Full / Double, 53 × 75 in	Double, 4 ft 6 in
Queen	150 × 190 cm	59.1 × 74.8 in	Queen, 60 × 80 in	King, 5 ft
King	200 × 190 cm	78.7 × 74.8 in	King, 76 × 80 in	Super King, 6 ft

Mexican size names aren't a fixed standard, so other brands may list slightly different measurements. Check the centimeters on any listing before you buy sheets, a frame or a mattress.

How each size compares

Individual vs US Twin

Very close. Our Individual is 3.5 cm (1.4 in) wider than a US Twin and 0.5 cm (0.2 in) shorter. Against a UK Single (3 ft, 90 cm wide) it's 10 cm (3.9 in) wider, same length. In Canada the Twin is also called a Single.

Matrimonial vs US Full and UK Double

The name says "marriage", the width says Full. Our Matrimonial is 0.4 cm (0.1 in) wider and 0.5 cm (0.2 in) shorter than a 53 in US Full. Some Canadian Fulls are 54 in wide; ours is 2.2 cm (0.9 in) narrower than those. It's exactly the size of a UK Double.

Queen vs US Queen

Same name, different bed. Our Queen is 2.4 cm (0.9 in) narrower and 13.2 cm (5.2 in) shorter than a US or Canadian Queen. If you're British: it's as wide as your King (5 ft) and 10 cm (3.9 in) shorter.

King vs US King

Our King is 7.0 cm (2.7 in) wider and 13.2 cm (5.2 in) shorter than a US King (193 × 203 cm). It's exactly two of our Individuals side by side. Next to a UK Super King (6 ft) it's 20 cm (7.9 in) wider and 10 cm (3.9 in) shorter.

Continental European mattresses are usually 200 cm long (for example 90, 140 or 160 cm wide), so they're 10 cm (3.9 in) longer than ours.

Bringing sheets or a bed frame from home

We haven't tested US or UK sheets on our mattresses, so we won't promise a fit. Here are the numbers to check against what you have:

• Depth: every SIMPLE mattress is 25 cm (9.8 in) tall. Your fitted sheet's pocket needs to cover that.
• US Queen sheets on our Queen: the fitted sheet is made for a mattress 13.2 cm (5.2 in) longer and 2.4 cm (0.9 in) wider, so expect slack at the foot.
• US King sheets on our King: made for a mattress 7.0 cm (2.7 in) narrower and 13.2 cm (5.2 in) longer. It may be tight across and loose at the foot.
• US Twin and Full sheets: within a few centimeters of our Individual and Matrimonial.
• UK Double bedding: made for exactly our Matrimonial size.

Bed frames matter more than sheets. A US Queen or King frame is built for a mattress 13.2 cm (5.2 in) longer than ours, so you'll have a gap at the foot. A US King frame is also 7 cm narrower than our King, so the mattress would overhang about 3.5 cm on each side. A memory-foam mattress needs a flat, firm, ventilated base; our Spanish guide on which base a memory-foam mattress needs covers slat spacing and box springs.

If you're tall

Every SIMPLE mattress is 190 cm (74.8 in) long, just under 6 ft 3 in. That's 0.5 cm (0.2 in) shorter than a US Twin or Full (75 in). A US Queen or King is 80 in (203.2 cm) long.

We don't make a longer size. If your feet reach the end of a US Queen or King today, they'll hang off ours. We'd rather tell you now than after you unbox it.

Buying a SIMPLE mattress

SIMPLE makes one memory-foam mattress, 25 cm tall with medium firmness (7/10), made in Mexico. It arrives rolled and compressed in a box, so it fits through narrow stairs and elevators.
