Quick snapshot facts

What is the size of a Royal Caribbean cruise ship?

Size is measured primarily in gross tonnage (GT), which reflects the ship’s internal volume — one GT = 100 cubic feet of enclosed space. Passenger capacity is a secondary metric.

Gross tonnage explained

• GT covers all enclosed spaces: cabins, restaurants, theaters, pools, engine rooms (Royal Caribbean official fleet guide)
• Royal Caribbean’s fleet spans from 73,817 GT (Grandeur of the Seas) to 250,800 GT (Star of the Seas) (Royal Caribbean official fleet guide)
• Length and beam vary: Icon of the Seas is 365 metres long, 66 metres wide at the bridge wings

Passenger capacity as a secondary size metric

• Double-occupancy capacities range from 2,050 (Grandeur) to 5,734 (Wonder of the Seas) (Royal Caribbean official fleet guide)
• Maximum capacity with all berths can exceed 7,000 on Icon-class ships

Royal Caribbean ships by class and age

Seven classes, one clear trend: each generation built larger than the last. Here is how they stack up.

Icon class (2024–present)

• First ship: Icon of the Seas (2024, 248,663 GT) (Royal Caribbean official fleet guide)
• Star of the Seas (planned 2026, 250,800 GT) (Cruise Critic analysis)
• Legend of the Seas announced for 2026+

Oasis class (2009–2024)

• Allure (2009, 225,282 GT), Harmony (2016, 226,963 GT), Symphony (2018, 228,081 GT), Wonder (2022, 236,857 GT), Utopia (2024, 236,473 GT) (Royal Caribbean official fleet guide)
• Size grew 5% over the class lifespan

Quantum class (2014–2021)

• Anthem (2015, 168,666 GT), Ovation (2016, 168,666 GT), Quantum (2014, 168,666 GT)
• Ultra variants: Spectrum (2019, 169,379 GT), Odyssey (2021, 167,704 GT) (Royal Caribbean official fleet guide)

Freedom, Voyager, Radiance, and Vision classes

• Freedom class (2006–2008): ~154,000–160,000 GT
• Voyager class (1999–2003): ~137,000–138,000 GT
• Radiance class (2001–2004): ~90,000–96,000 GT
• Vision class (1996–1998): ~70,000–83,000 GT; smallest is Grandeur of the Seas (73,817 GT) (Royal Caribbean official fleet guide)

The pattern: each new class pushes the fleet’s size ceiling higher, leaving older classes as the budget-friendly option for passengers who prefer smaller vessels.

Comparison: Icon class vs Oasis class

Two classes, one pattern: Icon is about 5% larger than the largest Oasis, but the difference is most noticeable in amenities (water parks, show venues) rather than cabin count.

Icon class sacrifices a few hundred lower-berth cabins in favour of more public space and premium accommodations.

Spec table: selected ships

Ten ships, two metrics: gross tonnage and passenger capacity vary by class, with the largest spread in the mid-size range.

What’s confirmed and what’s still unclear

Confirmed facts

• Icon of the Seas entered service January 2024 (Royal Caribbean official fleet guide)
• Utopia of the Seas entered service July 2024 (Royal Caribbean official fleet guide)
• Grandeur of the Seas is the smallest active ship at 73,817 GT (Royal Caribbean official fleet guide)
• Oasis class ships range from 225,282 to 236,857 GT (Royal Caribbean official fleet guide)

What’s unclear

• Star of the Seas exact delivery date may change (Cruise Critic analysis)
• Some older ships’ GT figures from non-official sources may vary slightly (Royal Caribbean official fleet guide)
• Future Legend of the Seas timeline not finalised (Royal Caribbean official fleet guide)

“Icon of the Seas represents a new era in cruise ship design, offering the largest waterpark at sea and over 40 dining venues.”

— Royal Caribbean press release, 2024

“The size ranking can be confusing because some sources use different figures for the same ship.”

— Cruise Critic editorial, 2025

The pattern is clear: Royal Caribbean’s strategy of building ever-larger ships has created two distinct fleets — the new, colossal Icon- and Oasis-class vessels, and the older, smaller ships that still serve popular itineraries. For a first-time cruiser considering a Western Caribbean sailing, the choice is not just between ports but between the experience of a 6,000-passenger resort and a 2,000-passenger classic.
