King vs Super King — What’s the Difference?
A standard UK king size duvet measures 220×220cm, designed for a 150×200cm king size bed. A super king duvet is 260×220cm, made for a wider 180×200cm bed. The extra 40cm in width makes a visible difference — super king duvets drape further down each side.
“For a king size bed, a 220×220cm duvet provides approximately 35cm of overhang on each side — the amount most sleep experts recommend for warmth and comfort.”
Does the Duvet Size Need to Match the Bed Exactly?
No — and it shouldn’t. A duvet sized exactly to your mattress would leave the sides exposed. The general rule is to choose a duvet at least 30–40cm wider than your mattress on each side. For a 150cm wide king bed, 220cm width gives exactly 35cm per side, which is the standard recommendation.
Why US and UK King Sizes Are Different
The UK “King” and US “King” refer to different bed dimensions. A US King bed is 193×203cm (76×80 inches) — wider and longer than the UK equivalent. This means US king duvets are larger: typically 264×224cm. Always check which standard your retailer uses, especially when buying online from international stores. Sleep quality is closely tied to bedding comfort, making the right size choice genuinely important.
