Princess Cruise Ships By Size: Largest to Smallest
Princess Cruises may be known for a few stand-out features — great service, excellent dining, etc. — but the line is not known for having ships that are particularly large.
That said, there’s a big difference between cruising on Princess Cruises’ largest ships — Star Princess and Sun Princess — and cruising on its smallest ship, Coral Princess. Here’s what you can expect on all the Princess ships, with the entire fleet listed by size, largest to smallest.

Star Princess
Star Princess isn’t just Princess Cruises’ largest ship (or, at least it’s tied for largest ship). It’s also the cruise line’s newest ship, debuting in 2025.
In addition to having a greater number of venues and staterooms, cruisers who’ve been on some of the line’s earlier ships will also notice overall larger dining venues and a larger casino on Star Princess.
Just like sister ship Sun Princess, Star Princess features the first geodesic dome at sea, known simply as The Dome. The ship features just over 2,150 staterooms and, in addition to carrying thousands of passengers, also carries over 1,500 crew members.
Gross tonnage: 175,500
Passenger capacity: 4,310
Length: 1,133 feet
Width: 158 feet
Sun Princess
Debuting just slightly earlier than sister ship Star Princess, Sun Princess is the lead ship in the Sphere Class, Princess Cruises’ newest class of ships. The ship, along with Star Princess, represents the biggest vessels in the cruise line’s fleet.
Just how big is Sun Princess? Well, in addition to tying with Star Princess in measurement by gross tons, the ship also offers 30 restaurants and bars, five pools and more than 5,000 square feet of shopping. Across the shopping area, there are more than 25 brands that are appearing on a cruise ship for the very first time.
Gross tonnage: 175,500
Passenger capacity: 4,310
Length: 1,132 feet
Width: 139 feet
Discovery Princess
Before the Sphere Class introduced the largest ships in Princess Cruises’ fleet, Discovery Princess held the title of largest ship for the line. The Royal-class ship features 19 decks, just over 1,800 staterooms, 20 restaurants and bars, four pools and 10 hot tubs. The ship is manned by just over 1,300 crew members.
Gross tonnage: 145,000
Passenger capacity: 3,660
Length: 1,083 feet
Width: 126 feet
Enchanted Princess
Next up in Princess Cruises’ ships by size are another two tie-holding ships, in the Royal Class. Enchanted Princess and Sky Princess are sister ships and are both just slightly smaller than Discovery Princess — though by gross tonnage, not passenger capacity.
Enchanted Princess offers 1,800 staterooms and is manned by just under 1,350 crew members.
Gross tonnage: 144,650
Passenger capacity: 3,660
Length: 1,083 feet
Width: 126 feet
Sky Princess
As mentioned, Royal-class ship Sky Princess is identical in size to sister ship Enchanted Princess. This means she’s very nearly the size of Discovery Princess, only off by a few thousand GT.
That smaller size means fewer of some features, like hot tubs, but it doesn’t mean Sky Princess didn’t still offer lots to love when the ship debuted in 2019. At the time, it boasted some of the largest balconies at sea.
Gross tonnage: 144,650
Passenger capacity: 3,660
Length: 1,083 feet
Width: 126 feet
Majestic Princess
The slow downward creep in ship size continues with Majestic Princess, which is just a few thousand gross tons smaller than Sky Princess and Enchanted Princess. This smaller size results in being able to handle just about a hundred fewer passengers, with overall fewer staterooms.
Majestic Princess, though, stands out in more ways than mere size. It was also specifically constructed for the Chinese market. This means that the ship features different entertainment venues, restaurants and bars than what you’d find on the other Royal-class ships.
Gross tonnage: 143,700
Passenger capacity: 3,560
Length: 1,082 feet
Width: 126 feet
Regal Princess
Regal Princess and Royal Princess are both tied in size next, at slightly smaller than Majestic Princess in gross tonnage, while still able to handle the same passenger capacity. Don’t think that just because these two ships are tied for size, though, that they’re identical.
Princess Cruises changed up a few things with Regal Princess, the second Royal-class ship, by adding an aft pool and promenade deck to the ship, whereas Royal Princess has neither of these features.
Gross tonnage: 142,229
Passenger capacity: 3,560
Length: 1,082 feet
Width: 126 feet
Royal Princess
Lead ship of its class, when Royal Princess debuted, the ship was about a good 30,000 GT larger than all of the Princess Cruises ships to come before it. As such, the ship had space for lots of new features, including new restaurants and bars, private cabanas and the SeaWalk, an over-water glass floor walkway.
With nearly 2,000 cabins to hold its 3,500-plus cruisers, the ship carries a crew of about 1,350 crew members — not dissimilar to some of the larger, newer ships that came after.
Gross tonnage: 142,229
Passenger capacity: 3,560
Length: 1,083 feet
Width: 126 feet
Sapphire Princess
Next up, Sapphire Princess debuted about a decade earlier than Royal Princess, and the Gem-class ship is about 30,000 GT smaller.
The ship offers 18 decks, about 1,300 staterooms and five main dining rooms. It’s also has received a handful of dry docks over its lifetime, which have added other new features, like mini suites, that the ship did not have when it entered service in 2004.
Gross tonnage: 115,875
Passenger capacity: 2,680
Length: 952 feet
Width: 123 feet
Diamond Princess
Diamond Princess also entered service in 2004, alongside Sapphire Princess. The two ships tie for size, as far as gross tonnage and length are concerned, but Diamond Princess can carry just about a hundred more cruisers.
Diamond Princess, though, stands apart from its sister ships by being developed specifically for the Japanese cruising market. As such, the ship features certain restaurants and entertainment options that other ships in its class do not.
Gross tonnage: 115,875
Passenger capacity: 2,710
Length: 952 feet
Width: 123 feet
Ruby Princess
Next are three slightly older ships that all tie for size. The entire Crown Class — Ruby Princess, Emerald Princess and Crown Princess — are all the same size and all just a tad smaller than Diamond Princess and Sapphire Princess (by gross tonnage, not passenger capacity).
While they still manage to offer the main cruising venues and amenities that modern travelers expect from cruise ships, they only have around 1,500 staterooms. They can hold about 3,000 passengers.
Gross tonnage: 113,561
Passenger capacity: 3,080
Length: 951 feet
Width: 118 feet
Emerald Princess
Very similar to its sister ships, Emerald Princess offers just around 1,500 staterooms to its 3,000-plus passengers. There are three main dining rooms on the ship, as well as a nice selection of additional restaurants, bars and lounges.
The ship additionally features all the public and entertainment venues you’d expect from a ship of this size, including a casino, sports deck, kids clubs, fitness center and the Lotus spa. There are four pools and seven hot tubs.
Gross tonnage: 113,561
Passenger capacity: 3,090
Length: 951 feet
Width: 188 feet
Crown Princess
Crown Princess is much the same. With its 3,000-plus passengers and crew of 1,200 members, it stretches over 19 decks. There are 1,545 staterooms, the majority of which are exterior staterooms, mostly balcony rooms.
There are three main dining rooms and much of the same amenities that you’ll find on Emerald Princess. In addition to the four main pools and seven hot tubs, though, there is also a splash pool.
Gross tonnage: 113,561
Passenger capacity: 3,090
Length: 952 feet
Width: 118 feet
Caribbean Princess
When Caribbean Princess debuted in 2004, it was Princess Cruises’ largest ship by passenger capacity to date and it held that title for years, until Royal Princess took that crown just about a decade later.
That said, Caribbean Princess still features more decks than any of the other Grand class ships, which is something that no new cruise ship can take away.
Gross tonnage: 112,894
Passenger capacity: 3,140
Length: 952 feet
Width: 118 feet
Grand Princess
For many cruise lines, the oldest ship in the fleet is usually the smallest, but that’s not the case with Princess Cruises. Instead, Grand Princess, the oldest ship for the cruise line at just under three decades old, is only the third-smallest ship in the Princess fleet.
While this ship is considered mid-size by today’s standards, in the late 1990s, when it debuted, it was considered very large, with some of the best features in the industry.
While that’s no longer the case, the ship has still managed to remain somewhat modern, with regular dry docks adding new features and enhancements, such as new eateries, lounges, kids clubs and more.
Gross tonnage: 107,517
Passenger capacity: 2,610
Length: 949 feet
Width: 118 feet
Island Princess
One of two Coral Class cruise ships, Island Princess ducks down beneath 100,000 GT. The ship holds just over 2,000 passengers, and thanks to the ship’s sleek design, it can pass through the Panama Canal. The ship has 16 decks and about a thousand staterooms, two main dining rooms, three pools and a handful of other venues.
Gross tonnage: 92,822
Passenger capacity: 2,210
Length: 964 feet
Width: 106 feet
Coral Princess
The very smallest ship in the Princess Cruises fleet, Coral Princess is about a thousand GT smaller than sister ship Island Princess. However, that said, it does have more staterooms than Island Princess, by about 500 extra.
Gross tonnage: 91,621
Passenger capacity: 2,000
Length: 964 feet
Width: 106 feet
What’s Different Between the Larger and Smaller Princess Cruise Ships?
There are vast differences between the largest and smallest Princess Cruises’ ships.
The largest ships in the Princess Cruises fleet are the Sphere-class ships: Sun Princess and Star Princess, which debuted in 2024 and 2025, respectively. These ships both measure in at 175,500 GT, with capacity to hold more than 4,000 passengers.
Princess Cruises boasts that Sun Princess, and Star Princess with it, is the most impressive and luxurious of its fleet to date. The stand-out feature is, of course, the feature for which the class is named, The Dome, the geodesic, first-of-its-kind structure that sits atop the ship.
The ship offers 30 restaurant and bar concepts, a VIP ship-within-a-ship area for exclusive amenities open only to guests, five pools, nine hot tubs, first-at-sea retailers and a huge range of other entertainment and public spaces.
In contrast, the smallest ship in the Princess Cruises fleet is Coral Princess. It’s just over 90,000 GT, and can only hold about 2,000 passengers over 1,545 staterooms, plus less than a thousand crew members.
As such, it’s just about half the size of the Sphere-class ships. But does that mean that Coral Princess is half the fun? Not necessarily!
Coral Princess is an ideal fit for those who want a more intimate and low-key cruising experience, wherein they’re not bogged down with near-endless options and crowds. The ship has just two main dining rooms, plus 10 other dining options; five bars and lounges; a theater; four pools; and five hot tubs.
The Ever-Changing Fleet
Princess Cruises seems to be steadily growing the fleet, and these ships are, for the most part, larger and larger with each new one to debut.

As mentioned, the newest and largest ships in the fleet are Sun Princess and Star Princess, of the Sphere Class. While further ships are definitely expected, a third Sphere-class ship has yet to be announced, though it’s safe to assume it will be at least as big as Star Princess, if not larger.
