List of Royal Caribbean Ships by Size

Below, I have put together a list of Royal Caribbean ships ranked by size, first by ‘gross tonnage’, then by length in feet. So you know, ‘gross tonnage’ is just a fancy way to quantify a ship’s total internal volume.

I have also included each ship’s total guest capacity, total staterooms and number of crew members.

With Legend of the Seas joining the fleet in July 2026, Royal Caribbean now has 30 ships, ranging from the record-breaking Icon Class to the smaller Vision Class vessels.

The Biggest Royal Caribbean Ship: Legend of the Seas

Legend of the Seas is currently the largest Royal Caribbean ship and also the largest cruise ship ever built. With a gross tonnage of approximately 250,800 and a length of 1,198 feet, she’s longer than the Eiffel Tower, which is 984 feet tall.

She joined the fleet in July 2026 as the third Icon Class ship, following Icon of the Seas in 2024 and Star of the Seas in 2025.

The three ships are in a class all their own. Legend of the Seas surpasses her sister ships by just over 2,100 gross tons and is around 14,300 gross tons larger than Utopia of the Seas, the biggest ship in Royal Caribbean’s Oasis Class.

She features 20 decks and can accommodate up to 7,600 guests. Additionally, she requires a crew of approximately 2,350 to operate. If you’re considering your accommodation options, the ship offers around 2,805 staterooms.

And there’s certainly no shortage of things to do. Legend of the Seas has seven pools, the Category 6 waterpark, and 28 dining venues, alongside plenty of entertainment.

Royal Caribbean isn’t stopping there, either. Another Icon Class ship, Hero of the Seas, is scheduled to debut in August 2027, with more pools, dining options, and family-friendly attractions.

But for now, Legend of the Seas holds the title of the largest ship in the fleet.

The Smallest Royal Caribbean Ship: Grandeur of the Seas

The smallest Royal Caribbean ship is Grandeur of the Seas. Built back in 1996, her stats might not be record-breaking, but she still appeals to many cruisers with a gross tonnage of around 73,817 and stretching 916 feet from bow to stern.

Part of the Vision Class, Grandeur of the Seas offers a cruising experience that’s less about overwhelming options and more about ease and familiarity. You’re looking at a guest capacity of around 2,440 passengers, complemented by a crew of approximately 760.

What Grandeur of the Seas lacks in size, she more than makes up for in character. Boasting around 1,000 staterooms and various amenities, the ship provides everything you need for a fulfilling vacation at sea.

And despite being almost 30 years old, she’s still going strong. So, if the hustle and bustle of the bigger ships isn’t your cup of tea, this might just be your perfect match.

The Size of Each Royal Caribbean Class

Next, diving into the various classes of Royal Caribbean ships, there are eight in total, each with unique features. The classes often consist of sister ships, which are quite similar in design, albeit with differences in on-board amenities. That’s one reason you might find variations in size, even among ships of the same class.

But to give you a clearer picture, I’ve crunched the numbers and calculated the average gross tonnage for each class. Here’s the breakdown:

1. Icon Class: 250,800 
2. Oasis Class: 228,000 
3. Quantum: 169,000 
4. Quantum Ultra Class: 169,000 
5. Freedom Class: 154,000 
6. Voyager Class: 138,000 
7. Radiance Class: 90,000 
8. Vision Class: 78,000 

These numbers give you a good idea of what to expect size-wise when choosing between the different classes.

Royal Caribbean also has a brand-new Discovery Class in the works, with the first ship expected in 2029 and a second following in 2032. They’re expected to be smaller than the huge Icon Class ships, although Royal Caribbean hasn’t revealed their actual size yet.

What we do know is that they’re being designed to accommodate around 4,300 passengers at double occupancy. So, it’ll be interesting to see where they fit among the existing classes once the full details are announced.

What’s interesting is that Royal Caribbean’s newest Icon Class ships are now more than three times the size of some of its smallest vessels. That’s quite a difference!

So, whether you’re after the largest ship or something a bit more intimate, Royal Caribbean has something for everyone.

Are Bigger Royal Caribbean Ships Necessarily Better?

After taking a dive into the details and doing the math, I’ve made a table to help answer this question. I’ve worked out two things for each ship: firstly, how much space there is for each guest (space ratio – the higher number, the better). I’ve ordered the table by this metric, which is calculated using each ship’s maximum capacity.

Secondly, I added a column on how many crew members there are to look after you (passenger-to-crew ratio – the lower the number, the better). This should give you a better idea of what to expect on your cruise.

Keep in mind that the space ratio isn’t a measurement of actual personal space. It divides the ship’s gross tonnage by its maximum guest capacity, so it’s best used as a general comparison rather than a guarantee of how crowded a ship will feel.

Ship Name	Class	Space Ratio	Gross Tonnage	Total Guest Capacity	Passenger-to-Crew Ratio
Radiance of the Seas	Radiance	36.5	90,090	2,466	2.76
Serenade of the Seas	Radiance	36.4	90,090	2,476	2.80

Spectrum of the Seas	Quantum Ultra	30.9	169,379	5,480	3.53
Odyssey of the Seas	Quantum Ultra	30.4	167,704	5,510	3.42
Enchantment of the Seas	Vision	30.4	82,910	2,730	3.20
Grandeur of the Seas	Vision	30.3	73,817	2,440	3.21
Utopia of the Seas	Oasis	29.7	236,473	7,958	3.48

From this, here are a few things I noticed from the table:

• More Space on Smaller Ships: Some smaller ships, like those in the Radiance Class, seem to give you more personal space. Radiance of the Seas still tops the rankings, despite being much smaller than the newer ships. So, if you hate feeling cramped, a smaller ship might be a good option.
• Bigger Ships, More People: On large ships like those in the Icon and Oasis classes, there are more guests onboard, and some have higher passenger-to-crew ratios. This could mean you’ll wait a bit longer for that cocktail or dinner table, although staffing ratios alone don’t tell the whole story. Remember, the bigger ships have lots more options for things to do: more pools, restaurants, and entertainment.
• Best of Both Worlds: Some ships, like those in the Quantum and Freedom classes, are in the middle ground. They offer a good amount of personal space and a reasonable number of people per crew member.

One interesting result is that Legend of the Seas, despite being the largest ship in the fleet, has a slightly better space ratio than Icon of the Seas and Star of the Seas when using the published maximum capacities.

But none of the Icon Class ships comes close to Radiance of the Seas in these calculations.

So, what’s the takeaway? There isn’t a massive difference in the amount of space for each passenger or the number of crew members per guest across much of the fleet, although some ships clearly offer a little more room on paper.

And with the upcoming Discovery Class expected to be smaller than Royal Caribbean’s biggest ships, it’ll be interesting to see whether they offer a little more breathing room without sacrificing too many of the features cruisers love.

However, bigger isn’t necessarily better; it just depends on what you want. If it’s a more relaxed atmosphere and fewer crowds, you might appreciate a smaller ship. If it’s endless activities and amenities, a bigger ship might suit you better.

Wrapping It Up

Choosing the right Royal Caribbean ship for your vacation isn’t just a matter of picking the largest ship in the fleet, although, if that’s what floats your boat (pun intended), why not go all out with Legend of the Seas?

The key takeaway is that each ship offers a unique cruising experience, influenced by its size, amenities, and passenger-to-crew ratio.

For those who want a ship with plenty of activities, the bigger ships like those in the Icon and Oasis classes might be your ideal match. On the other hand, if you’re looking for a more intimate, laid-back vacation with a more traditional cruising atmosphere, you may find yourself drawn to the smaller ships in the Radiance or Vision classes.

However, remember that ships that fall in the middle of the size spectrum, like the Quantum and Freedom classes, offer a balanced experience that can give you the best of both worlds.

And with Hero of the Seas arriving in 2027, followed by the brand-new Discovery Class in 2029, Royal Caribbean’s fleet is set to become even more varied. Bigger ships are still coming, but it seems the cruise line hasn’t forgotten about those who prefer something a little smaller.

In the end, whether you’re sailing solo, with a partner, or with the whole family, there’s a Royal Caribbean ship that’s just the right size for your perfect vacation at sea.
