Icon of the Seas size comparison

Icon of the Seas is the biggest cruise ship in the world, but how much bigger is Icon compared to other ships?

Modern cruise ships are well-known for being giant, but Icon has raised the bar yet again just how large ships can get.

Royal Caribbean already has a fleet of really big ships, but Icon dwarfs them all.

How big is Icon of the Seas?

Icon of the Seas is indeed really big.   The new ship measures 1,198 feet long with 250,800 gross tonnage and is capable of carrying 7,600 guests and 2,350 crew members. The ship is encompasses 20 decks, has seven pools, and six waterslides that make up an entire waterpark.

If you were to stand Icon of the Seas up on its end, it would be taller than the Stratosphere Tower in Las Vegas and the Chrysler Building in New York City.

Icon of the Seas is divided into 8 neighborhoods, which are distinct areas of the ship meant to make it easier to navigate.

• AquaDome is at the front of the ship, offering 220-degree views and a 55-foot waterfall
• Suite Neighborhood has a Mediterranean restaurant and two-floor sundeck
• Central Park is a five deck open-air park that has living plant walls
• Chill Island has four pools and a swim-up bar
• Thrill Island is where you'll find the Category 6 waterpark, FlowRider surf simulator, rock climbing wall, mini-golf course and more.
• Surfside neighborhood designed for young families
• Royal Promenade shopping and entertainment district
• The Hideaway at the back of the ship offering 180-degree views and an infinity pool

There are over 2,800 staterooms on Icon of the Seas, as well as over 40 bars and restaurants onboard (23 of them are completely new to Royal Caribbean).

Is Icon of the Seas the biggest cruise ship in the world?

Icon of the Seas will become the biggest cruise ship in the world, overtaking Wonder of the Seas by gross tonnage, passenger capacity, and length. 

It's unlikely any other cruise ship will overtake Icon of the Seas, until Star of the Seas debuts in 2025. But even then, Star should be the same size as Icon.

It can be confusing how to measure a cruise ship, because gross tonnage is a nonlinear measure of a ship's overall internal volume.

What this means in layman's terms is that cruise ships are measured by volume and not weight.  This is because their designs can vary greatly, so it makes more sense to measure a ship in this manner.

At 250,800 tons, Icon of the Seas measures 6% bigger than Utopia of the Seas, which amounts to a difference of 13,940 GT. 

As you can see, the difference in size between Icon and the Oasis Class ships isn't enormous, but it's enough to call it the biggest cruise ship in the world.

When Royal Caribbean set out to design Icon of the Seas, they didn't have a particular tonnage in mind.  

According to Jay Schneider, Royal Caribbean's Senior Vice President and Chief Product Innovation Officer, they had a completely different goal in mind, "We’ve been working on Icon since 2016–2017, if you go back to our original memo that starts off a new class of ship. Typically, that process is about aspiration. It doesn’t detail things like we want a ship that weighs 250,000 tons."

"Instead, it’s aspirational and rooted in what we would say as a headline. This ship’s headline is: this is the best family vacation on the planet."

And in case you're wondering, Icon of the Seas is about 5 times bigger than Titanic.

All the new features are a bigger difference maker

While Icon of the Seas is not substantially larger than Utopia of the Seas or Wonder of the Seas, what Royal Caribbean is adding to Icon is more notable.

Royal Caribbean wants this ship to offer more for families to see and do with additional attractions and amenities that the line hopes will attract customers away from land resorts.

The cruise ship's water park, family neighborhood, and staterooms designed for families with five and six passengers are at the heart of this drive.

So far, the demand for a cruise ship this big and with this much to do for families has been a mega hit for the cruise line. It's broken sales records and forced the company to release more sailings earlier than planned in order to meet demand for new bookings.
