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, ill-fated Titanic was the largest and grandest passenger vessel of its time. But since 2009, when Royal Caribbean debuted its first Oasis Class ship, those superlatives have applied to vessels more than five times Titanic’s size.

Today, the largest cruise ships are floating cities, offering a plethora of bars and restaurants, expansive spas and sun deck retreats. They feature scores of recreation opportunities, including zip lines, surf simulators, rock climbing walls, ice-skating rinks, escape rooms, laser tag, top-deck go-karts, virtual reality gaming and even roller coasters.
So, what is the largest cruise ship in the world, and how do other cruise ships compare? Here’s a quick rundown of the world’s biggest cruise ships by both gross registered tons and maximum passenger capacity.

What cruise ship is 5 times bigger than Titanic?
All of the ships in Royal Caribbean’s Oasis Class and Icon Class are at least five times larger than Titanic was, in terms of size.

Icon of the Seas can hold up to 7,600 guests at maximum capacity or 5,610 guests on a double occupancy basis (two people per cabin). The ship also employs more than 2,300 crew members. That means the ship can carry nearly 10,000 people when it’s fully crewed and every passenger bed is occupied.
