Which is bigger
US King is the larger by 40.7% in area. US King is 55.9 cm wider, and both are 203.2 cm long.
Which one to buy
Same length, 55.9 cm apart in width — 28 cm per sleeper. Nobody gets to stretch out further; the whole difference is elbow room, which matters if two people share it and not at all if one does.
Does the same bedding fit both?
No. 55.9 cm of width is far outside what a fitted sheet absorbs. Buy for the size you own and read the centimetres, not the label.
Space per person
Shared between two adults, Full XL gives each sleeper 69 cm and US King gives 97 cm. For comparison, a single bed is 90 cm wide, so anything under that is less room each than a single bed gives one person.
Room each one needs
With 60 cm to walk down each side and 60 cm at the foot: 257.2 × 263.2 cm for Full XL, 313 × 263.2 cm for US King — a difference of 55.9 cm in the room, not just the bed. Against a wall on one side, take 60 cm off.
