Tonnage is easier to look up than square footage.
Tonnage is a measure of volume (not simply displacement) so the high overheads on QM2 Deck 2 and 3 will add more volume (tonnage) although they won't add more square footage, but I think the height of those decks helps add to the feeling of spaciousness which I think is what you're after.
