Mexican mattress sizes vs US sizes, in cm and inches

SIMPLE sizes next to US, Canada and UK sizes

These are the four common Mexican bed sizes, but the names aren't a fixed standard. Check the centimeters on any listing.

Our listed sizes, confirmed 2026-09-24. Width × length. Like any foam mattress, ours can differ from the listed size by up to 2–3 cm (it's in our terms), so treat differences under 1 cm as "the same". 1 in = 2.54 cm exactly, rounded to one decimal place.

• Our King (200 × 190 cm) is exactly two Individuals (100 × 190 cm) side by side.
• Continental Europe: Silentnight's guide lists EU mattresses of 90 × 200, 140 × 200, 150 × 200 and 160 × 200 cm, all 10 cm (3.9 in) longer than ours.

Sheets and frames from home: numbers, not promises

We haven't tested US or UK sheets on our mattresses, so we won't guess. Check these numbers against your sheets and bed frame:

• Every SIMPLE mattress is 25 cm (9.8 in) deep.
• A US Twin is 3.5 cm (1.4 in) narrower and 0.5 cm (0.2 in) longer than our Individual.
• A US Full (53 in) is 0.4 cm (0.1 in) narrower and 0.5 cm (0.2 in) longer than our Matrimonial. Some Fulls sold in Canada are 54 in, 2.2 cm (0.9 in) wider than ours.
• A US Queen is 2.4 cm (0.9 in) wider and 13.2 cm (5.2 in) longer than our Queen.
• A US King is 7.0 cm (2.7 in) narrower and 13.2 cm (5.2 in) longer than our King.
• A UK Double is the same size as our Matrimonial: 135 × 190 cm.
• A UK King is as wide as our Queen and 10 cm (3.9 in) longer.
• A US Queen or King bed frame is made for a mattress 13.2 cm (5.2 in) longer than ours.

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, 190.5 cm).

A US Queen or King is 80 in (203.2 cm) long. A US California King is 84 in (213.4 cm), 23.4 cm (9.2 in) longer than ours.

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. If they already hang off a US Full, they'll hang off ours too. We'd rather tell you now than after you unbox it.

Questions expats ask

What size is a matrimonial bed? Is it a Full?

Nearly. Matrimonial is the Mexican name for a double. Ours is 135 × 190 cm (53.1 × 74.8 in): about a US or Canadian Full (53 × 75 in) and exactly a UK Double (135 × 190 cm). The name says marriage; the width says Full.

Is a Mexican Queen the same as a US Queen?

No. Our Queen is 150 × 190 cm (59.1 × 74.8 in). A US or Canadian Queen is 60 × 80 in (152.4 × 203.2 cm). Ours is 2.4 cm (0.9 in) narrower and 13.2 cm (5.2 in) shorter.

What size is a king-size bed in Mexico?

Usually 200 × 190 cm (78.7 × 74.8 in), and that's ours. Next to a US King (76 × 80 in, 193.0 × 203.2 cm) it's 7.0 cm (2.7 in) wider and 13.2 cm (5.2 in) shorter. Not every Mexican listing agrees, so check the centimeters.

Is a Mexican Individual the same as a US Twin?

Close. Our Individual is 100 × 190 cm (39.4 × 74.8 in). A US Twin, called Twin or Single in Canada, is 38 × 75 in (96.5 × 190.5 cm). Ours is 3.5 cm (1.4 in) wider and 0.5 cm (0.2 in) shorter.

I'm British. Is your King my King?

No. A UK King (5 ft, 150 × 200 cm) is the width of our Queen and 10 cm (3.9 in) longer. Our King (200 × 190 cm) is 20 cm (7.9 in) wider than a UK Super King (6 ft, 180 × 200 cm) and 10 cm (3.9 in) shorter. Your 4 ft 6 in Double is exactly our Matrimonial.
