List of Royal Caribbean Cruise ships – Largest to Smallest
When we talk about measuring Royal Caribbean ships by size, they are always measured in ‘Gross Tonnage’. You will often come across this term when you want to know about a particular ship’s size.

In all, Royal Caribbean Cruises has seven classes, each categorising a collection of ships. Here they are:
