Always use the actual measurements in centimetres or inches when checking whether a mattress will fit your bed frame, bedroom, fitted sheet or mattress protector.
No. A “5-foot bed” normally describes the approximate width, not both dimensions.
A 5-foot bed is approximately 152 cm wide, but the mattress will have a separate length.
For example, two mattresses can both be 5 feet wide while having different lengths. This is why a bed width alone is not enough to determine the full mattress size.
For complete width × length measurements, see Hush Home's Hong Kong Mattress Size Guide.
Hush Home lists mattress sizes using their actual measurements in feet, inches and centimetres, alongside familiar size names.
The same width can sometimes be available in more than one length. For example, a 3-foot Hush Home mattress may be available as a Single at approximately 91 × 183 cm or a Single Long at approximately 91 × 190 cm.
For current full dimensions and mattress availability, check the Hong Kong Mattress Size Guide.
Not necessarily.
Terms such as Single, Double, Full, Queen and King can refer to different measurements in different countries and between different mattress brands.
A mattress described as a Queen in Hong Kong, for example, should not automatically be assumed to have exactly the same dimensions as every Queen mattress sold in the UK, US, Australia or another market.
When comparing mattresses, bed frames or bedding, use the actual width and length in centimetres or inches rather than relying only on the size name.
If you are comparing complete mattress dimensions, see our Hong Kong Mattress Size Guide.
You can convert any bed measurement using these formulas.
Centimetres = feet × 30.48
Example: 3.5 × 30.48 = 106.68 cm
Inches = feet × 12
Example: 4.5 × 12 = 54 inches
Centimetres = inches × 2.54
Example: 60 × 2.54 = 152.4 cm
Feet = centimetres ÷ 30.48
Example: 183 ÷ 30.48 ≈ 6 feet
It depends on what you are buying.
If you are replacing a mattress for an existing bed frame, measure the space where the mattress will sit. Do not assume that the outside dimensions of the bed frame are the same as the mattress dimensions.
If you are buying fitted sheets, a mattress protector or other fitted bedding, measure the mattress itself, including its width, length and, where relevant, depth.
If you are planning a bedroom layout, remember that a bed frame is usually larger than the mattress it holds. See our Hong Kong Bed Frame Size Guide for mattress and bed-frame measurements.

No. Mattress size names and dimensions can vary between markets. Compare the actual width and length in centimetres or inches instead of assuming that a Single, Double, Queen or King has identical measurements everywhere.
Yes. Measure the mattress's width and length, and its depth when buying fitted bedding. If buying a bed frame, also check the frame's recommended mattress size and external dimensions.
