Small Single = 2'6" x 6'3"
Single Size = 3' x 6'3"
Small Double Size = 4' x 6'3"
Queen Double Size = 4'6" x 6'3"
King Size = 5' x 6'6"
Super King Size = 6' x 6'6"
Where did you find these "official" dimensions for beds? In the US, a standard Eastern king is 76" wide! Even the narrower California king is 72". I'm in a hotel room right now without a tape measure, but using my own height as a guide, the bed is 6' (72") wide.
ETA: I see the OP is in UK, and these measurements apply. But still, I'm with GentleGiant - 6" makes a huge difference, whether it's between King & Queen or Queen & Double. I wouldn't be happy with a downgrade.
