The size of a ship is measured by the amount of water it displaces – called tonnage. If we take the tonnage of a ship in relation to the number of passengers that it can house at full occupancy we are getting a passenger space ratio. The number is simple to interpret: The higher it is, the more space a passenger has available.
Please note though, that this is not measuring the size of cabins, but it rather shows the ratio between all (public & private) rooms and the number of passengers.
