Which one to buy
A trade rather than an upgrade: Emperor is 7 cm wider, US King is 3.2 cm longer. Width if two people share it, length if one of them is tall — you cannot have both without leaving this pair.
Does the same bedding fit both?
It will go on, but not well. The gap is 7 cm in width and 3.2 cm in length. A fitted sheet will strain on Emperor and wrinkle on US King; flat sheets and duvet covers are more forgiving.
Space per person
Shared between two adults, US King gives each sleeper 97 cm and Emperor gives 100 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: 313 × 263.2 cm for US King, 320 × 260 cm for Emperor — a difference of 7 cm in the room, not just the bed. Against a wall on one side, take 60 cm off.
