Ships with the most room per guest

Space ratio is the ship's gross tonnage divided by the number of guests it carries at two per cabin. It is the industry's own measure of elbow room, and it predicts a quiet pool deck and a short buffet queue better than any star rating does.

Over 3,000 guests

70 ships in the catalog carrying over 3,000 guests, roomiest first.

What this measure does not tell you

Space ratio only compares ships of a similar size, which is why this page is grouped rather than ranked as one list. A 100-guest expedition ship will beat every megaship on this measure and is not competing with them. It also measures volume, not design: a ship can spend its tonnage on a theatre nobody uses.

These lists rank the ships in our catalog, not every ship afloat. Ships whose figures we have not read off an operator document are left out rather than estimated.
