What Is the Largest Cruise Ship in the World?

By gross tonnage, the largest cruise ship in the world is Royal Caribbean’s Symphony of the Seas. The megaship has a gross tonnage of 228,081, is 1,184 feet (361 meters) long, and has a maximum passenger capacity of 6,680 people. Interestingly, its predecessor, Harmony of the Seas, retains the largest cruise ship capacity title, with the ability to hold 6,687 people at maximum, seven more than Symphony. Royal Caribbean’s Freedom-class and Oasis-class ships have held the title of largest passenger ship continuously since 2006. In 2021, Royal Caribbean is projected to retain the title with the launch of Wonder of the Seas, which will become the new largest cruise ship in the world once construction is completed.

The biggest Carnival ship, Carnival Panorama, pales in comparison at a mere 1,055 feet (322 meters) in length, a gross tonnage of 135,225, and maximum passenger capacity of 5,146 people.

How Big Was the Titanic vs. Modern Ships?

In April 1912, the RMS Titanic was not only the largest passenger ship in the world, but it was the largest ship ever built. The Titanic was 882 feet (169.1) meters long and had a gross tonnage of 46,328 and a maximum passenger capacity of 2,435 people. Comparing the Symphony of the Seas vs the Titanic, Royal Caribbean’s biggest ship categorically dwarfs the Titanic’s size in every way, more than doubling its passenger capacity and nearly quintupling its gross tonnage. The Titanic’s length, however, is still competitive at about 75 percent of Symphony’s. Conducting a Titanic size comparison with ships built in more than a century of technological advancements since isn’t exactly fair, but it helps provide a relatable benchmark nonetheless.

What Is the Difference Between an Ocean Liner and a Cruise Ship?
