Royal Caribbean's ship classes are known for offering some of the biggest cruise ships in the world.

Royal Caribbean groups its ships in classes, which are based largely on the ship general design and structure.
Within each ship class, there can be variations of features, restaurants, or activities that have been added or modified over the years. While there may be three, four, or more ships within a particular class, the exact onboard activities can vary.
You might be wondering what makes Royal Caribbean's ship classes different from each other, and it boils down to the size of the ship, onboard amenities, and signature activities offered.
There are seven Royal Caribbean cruise ship classes. Each ship in the class was built around the same time and from the outside certainly looks similar.
Here is an easy-to-understand breakdown of each class of ship, and what they offer.
How many classes are there in Royal Caribbean?
If you ask someone to describe a Royal Caribbean cruise ship, there's a good chance they'll start talking about all the things you can do onboard.
For decades, Royal Caribbean has made a name for itself by building cruise ships with, "I can't believe they put that on a cruise ship" features. Each new class of ship has come with a new array of whizzbang activities that capture the imagination. Royal Caribbean wants its ships to have something for everyone, and directly markets to the multi-generational travel market.
Over the years, the ships have become the destination just as much as the places around the world ships visit. You'll find plenty of restaurants, bars, outdoor activities, pool deck fun, and more.
While all Royal Caribbean ships have a common "DNA" of family vacation fun among them, each class of ship can vary in terms of what there is to do onboard.

If you've seen a Royal Caribbean television commercial in the last decade, then you have seen the largest cruise ships in the world featured, either an Icon Class, Oasis Class, or Quantum Class cruise ship.
The Icon Class is Royal Caribbean’s largest class of cruise ships and can hold 7,600 max guests (5,610 at double capacity). The first ship in the class, Icon of the Seas, will debut in January 2024.
Oasis Class ships can handle more than 6,000 passengers and dwarf every other cruise ship out there. There's one of everything on these ships, so you'll never run out of things to do.
The Quantum Class and Freedom Class cruise ships are relatively smaller than the Icon and Oasis Class, but offer quite a lot to do as well. The ships in these two classes are still mega ships and can handle between 4,000 - 5,000 passengers. These are big cruise ships that don't compromise on what you can enjoy onboard.
The last of the big ships in Royal Caribbean's fleet are the Voyager Class ships, which are slightly smaller versions of the Freedom Class. Royal Caribbean has been steadily upgrading Voyager Class ships over the last few years, which have added new amenities.
The last two classes of cruise ships are what many consider the "smaller" classes of ships, as they come in under 3,000 passengers.
The Vision Class and Radiance Class are more of a niche cruise ship now, with the ability to get into smaller ports of call. Many cruise fans that have been cruising for decades love these smaller ships for the intimacy you'll find.
Don't assume smaller ships mean boring. There's still restaurants, bars, outdoor activities, and shows every night. The difference is there is not nearly as many options as the bigger ships, so variety will be less.
It can be daunting to find the right class of ship to start with when you are new to Royal Caribbean. The key is to look at what features are available on each ship and then figure out which options are the most important to you.

Icon Class
When Icon of the Seas sets sail in 2024 from Miami, she will be the world’s largest cruise ship. She will be over 6% bigger than Royal Caribbean’s Oasis Class ships, and will offer nearly unlimited activities, amenities, and dining options onboard.
This is the first new class of ships since the Quantum Class debuted in 2014, and the Icon Class is the first class to be powered by LNG (liquefied natural gas).

Icon of the Seas will debut several new features not found elsewhere in Royal Caribbean’s fleet, including the cruise line’s first onboard waterpark and indoor AquaDome space.

- The AquaDome, home to an indoor AquaTheater and lounge space
- Central Park, an outdoor oasis with shops and restaurants
