144 bed cells — a Korean King and an American King differ by 33 cm
Names like “Queen” and “King” point at different objects in different countries. Twelve of them are gathered here and paired with the short wall of a room, working out the walkway left on each side. The problem people actually hit is the walkway, not the floor area.

The name is not a standard
A Korean Queen is 150 × 200 cm and an American Queen 152.4 × 203.2 — close enough. But at King the two part ways: 160 cm against 193, a gap of 33. An American King is wider even than a Korean Super King at 180. That is why matching names when buying bedding abroad leaves you with sheets that do not fit.
What you hit is the walkway
A room can be roomy on paper and still leave nowhere to walk once the bed is in. Squeezing past sideways needs about 60 cm on one side, and opening a wardrobe or a drawer needs more. So this table subtracts the bed’s width from the room’s short wall and halves what is left — push the bed against a wall and you give up one side but double the other.
Two people get less than a single bed each
Two people on a Korean Queen at 150 cm get 75 cm each. A single bed is 100 cm, so each sleeper has 25 cm less than a single. Even a King at 160 cm gives 80 cm apiece. The numbers make it plain: no matter how grand the name, sharing does not buy you a single bed’s width each.
The standard does not use these names
The Korean national standard fixes ranges for a mattress’s width and length but never uses words like “single”, “super single” or “queen”. Makers therefore agree closely from single up to queen, and diverge above king, where each company picks its own figures. The Korean numbers here are the trade’s common usage, not a legal size.
The frame is bigger than the mattress
These are mattress dimensions. A frame usually adds 5–15 cm of width, and a headboard adds length. Where the walkway is tight, check the frame’s own figures. Remember too that an inward-swinging door and the sweep of a wardrobe door both come out of the same walkway.

How to read this
- Walkway per side = (short wall − bed width) ÷ 2.
- Squeezing past needs about 60 cm on one side.
- Against a wall you lose one side but double the other.
- These are mattress dimensions; a frame adds 5–15 cm.
Frequently asked questions
Q. Is a Korean Queen the same as an American one?
Nearly. 150 × 200 cm against 152.4 × 203.2 — a couple of centimetres apart.
Q. And King?
Very different. A Korean King is 160 cm, an American King 193 — 33 cm wider, and wider even than a Korean Super King at 180.
Q. How much walkway does a Queen leave in a 3.6 m room?
105 cm on each side if centred, or 210 cm on one side if pushed against a wall.
Q. How much walkway do I need?
About 60 cm to squeeze past sideways. Opening drawers or a wardrobe needs more.
Q. Does the Korean standard define “single” and “queen”?
No. It fixes ranges for width and length without using the names, which is why king and above vary by maker.
