But, while it was the world's largest passenger liner at the time in 1912, the famous ship was actually significantly smaller than the cruise ships we know today.

Yes, almost all modern cruise ships are significantly larger than the Titanic in terms of length, height, and especially "Gross Tonnage" (volume). To put it in perspective, the Titanic was 269 meters (882 feet) long and had a gross tonnage of 46,328. In comparison, the current world's largest cruise ship in 2026, Royal Caribbean's Icon of the Seas, is 365 meters (1,197 feet) long and has a staggering gross tonnage of over 248,000—making it more than five times the volume of the Titanic. While the Titanic had only 9 decks, modern mega-ships frequently have 20 or more decks. Even a "standard" mid-sized cruise ship in 2026 is roughly double the size of the 1912 ocean liner. The main reason for this "size explosion" is the shift from transportation to "floating resort" entertainment; whereas the Titanic focused on speed and basic luxury for Atlantic crossings, modern ships are designed to house water parks, multiple theaters, and dozens of restaurants. Today's ships are essentially "floating cities" that dwarf the historic liner that was once the largest man-made moving object in the world.
