Angie Vognild Royal Caribbean International, one of the world’s largest and most innovative cruise lines, has a fleet of 29 ships as of 2025.
These cruise ships vary in size, from smaller, adventure-focused vessels to some of the largest cruise ships in the world.
In this guide, we’ll break down Royal Caribbean’s ships by size, organized from biggest to smallest.

Royal Caribbean ships by size: Picking the best cruise for your vacation
Not sure which Royal Caribbean ship size is best for you? Here are some tips to keep in mind:
- Families with kids or teens: Icon and Oasis class ships have the most activities, water slides, and venues for children.
- Adventure seekers: Quantum, Voyager, and Freedom class ships offer plenty of adrenaline-packed features without the mega-ship size.
- Frequent cruisers: If you’ve “been there, done that,” smaller ships, like Radiance or Vision class ships, often visit unique ports that the big ships can’t reach.
Whether you’re looking for non-stop action on the largest ship in the world or a relaxed vacation on a smaller ship, Royal Caribbean has a cruise ship for every kind of traveler.
