Bed names do not travel. A “queen” or a “king” is a different size in the UK, Europe and the US, so compare centimetres.

European beds are 200 cm long, and the double and king are 5 to 10 cm wider than UK ones: EU double 140 cm against UK 135 cm, EU king 160 cm against UK 150 cm. 180 × 200 cm is the same in both and is a super king in the UK.
