Does size really matter? The cruise industry thinks so. For more than a century, cruise lines have competed to claim the title of world’s largest cruise ship.

When it set sail in 1912, the ill-fated Titanic was the largest and grandest passenger vessel of its time. But, as of 2009, when Royal Caribbean debuted its first Oasis-class ship, the superlative applies to vessels more than five times Titanic’s size.

So, what is the biggest cruise ship in the world? At the time of publication, it’s Royal Caribbean’s Wonder of the Seas. At nearly 237,000 gross registered tons and carrying up to 6,988 passengers (plus 2,300 crew members), it’s a true behemoth. It boasts eight neighborhoods that feature everything from water slides, a zip line and a carousel to lavish suites, retail shops, thousands of live plants and more than two dozen bars and restaurants.

But where do other cruise ships fall? Here’s a quick rundown of the world’s biggest cruise ships by gross registered tons and maximum passenger capacity. Unsurprisingly, Royal Caribbean’s Oasis Class dominates the top five in both categories. Perhaps more surprisingly, only two other lines join it on the winner’s podium.

Note: I have excluded ships from lines like Costa Cruises, P&O Cruises and AIDA, which do not cater to the North American market.
