Hong Kong & international bed-size converter

A Queen or King label does not mean the same measurement everywhere. Choose a common size or enter your measurements to compare width and length.

Is a Hong Kong Queen the same as a UK King?

A common Hong Kong 5-foot Queen is 60 × 75 inches (152.4 × 190.5 cm). A UK King is usually 150 × 200 cm. The width is close, but the length differs by 9.5 cm. IKEA Hong Kong also sells a 150 × 200 cm Queen: check dimensions rather than names.

Bed-size comparison chart: Hong Kong, UK, US & metric

These are common retailer examples, not one worldwide standard. Hong Kong inch sizes are converted using 1 inch = 2.54 cm; shops often round centimetres. Lengths vary, and European size names are not consistent. IKEA sizes vary by range: verify the exact product.

How to convert mattress measurements

Multiply inches by 2.54 to get centimetres, or feet by 30.48. Divide centimetres by 2.54 for inches. For a 4 ft 6 in width, enter 54 inches or 4.5 decimal feet; do not enter 4.6 feet.

Common questions

How big is a Hong Kong 5-foot bed?

The width is 60 inches, or exactly 152.4 cm. Common lengths include 75 and 78 inches (190.5 and 198.1 cm). Confirm your mattress length before buying a fitted cover.

Is a US King the same as a Hong Kong King?

No. A common US King is 76 × 80 inches (193.0 × 203.2 cm); a common Hong Kong 6-foot King is 72 × 78 inches (182.9 × 198.1 cm). Both the width and the length differ.

Will the closest size fit my mattress?

A nearest-size comparison is only a way to compare measurements. It does not confirm compatibility for a bed frame, fitted sheet or Eight Sleep cover. Check exact dimensions and the product instructions.
