The Titanic and the Icon of the Seas have both held the title of the world's biggest ship. Royal Caribbean's Icon of the Seas, however, is a whopping five times the size of the Titanic. Photos show how the two ships' dining rooms, luxury bedrooms, and more compare.

When compared to the largest ships of 2026, the Titanic looks like a modest vessel rather than a giant. The current record-holder, Royal Caribbean's Icon of the Seas, is nearly five times the size of the Titanic by gross tonnage. Specifically, the Titanic measured 46,328 gross tons and was about 882 feet long; the Icon of the Seas is a staggering 248,663 gross tons and stretches to nearly 1,200 feet. In terms of capacity, the Titanic could hold around 3,300 people (including crew), while the Icon of the Seas can carry over 10,000 people at maximum capacity. To visualize the difference: the Icon is twice as wide as the Titanic and significantly taller, with 20 decks compared to the Titanic's 9. While the Titanic was an ocean liner built for speed and luxury transportation across the Atlantic, modern mega-ships are "floating cities" designed for entertainment, featuring entire water parks, surf simulators, and multiple theaters that would have been unimaginable a century ago.
