Carnival’s Vista class is five ships — Carnival Vista, Horizon, Panorama, Venezia and Firenze — built between 2016 and 2024, spanning 133,596 to 135,225 gross tons and carrying approximately 3,934 to 4,208 guests. The tonnage spread is about one percent, but the class is less uniform than that suggests: Carnival Firenze has 18 decks where Vista and Horizon have 15 and Venezia has 14. Venezia and Firenze are also the two Costa-built hulls, which is the real fork in this class.
Carnival Firenze has 18 decks. Carnival Vista, its sister ship in the same class, has 15. They are within 1,560 gross tons of each other. If you have ever been told that ships in a class are the same ship with different names, this is the class that disproves it, and the difference is large enough to change which cabin you want.
Which Vista-class ship to book
Book Carnival Firenze if you want the tallest ship in the class. In service since 2024, 135,156 gross tons, approximately 4,126 guests. Our data records it at 18 decks counting every deck aboard, against 15 for Carnival Vista on the same counting basis. That is a real structural difference, not a rounding.
Book Carnival Venezia for the largest hull. In service since 2023 at 135,225 gross tons carrying approximately 4,208 guests, it is the biggest ship in the class by both tonnage and capacity. It is recorded at 14 passenger decks — the fewest in the class — which tells you the extra volume went outward rather than upward.
Book Carnival Vista for the original. The lead ship, in service since 2016, 133,596 gross tons, approximately 3,934 guests, 15 decks. It is the smallest in the class on both tonnage and capacity.
Carnival Horizon (2018) matches Vista exactly on tonnage at 133,596 and carries approximately 3,960 guests across 15 passenger decks. Carnival Panorama (2019) is 133,868 tons, approximately 4,008 guests, 15 passenger decks.
The pattern worth seeing: the class splits cleanly in two. Vista, Horizon and Panorama are the 2016 to 2019 hulls at roughly 133,600 to 133,900 tons and under 4,010 guests. Venezia and Firenze are the 2023 and 2024 additions, both over 135,000 tons and over 4,100 guests. That is the fork in this class, and it matters more than the tonnage does.
The deck count problem, and why we are labouring it
Deck counts are not all measured the same way. Some sources count passenger-accessible decks; some count every deck including crew-only. Our figures for Carnival Vista and Carnival Firenze count all decks, while Horizon, Panorama and Venezia are recorded on passenger decks only.
That caveat does not rescue the comparison, though — it sharpens it. On the same all-decks basis, Firenze shows 18 against Vista’s 15. Three decks, between two ships in the same class, 1,560 tons apart. Whatever the counting convention, these are not the same vessel.
The practical consequence: a deck number from a class overview is not a deck number for your ship, and cabin location advice written for one hull may not transfer to its sister. Check the deck plan for the exact ship you are booking. Our cabin guide covers how to read one.
What the class is for
It is Carnival’s mid-large ship. Around 133,600 to 135,200 gross tons carrying roughly 3,930 to 4,210 guests. That sits it well above the older mid-fleet hulls and comfortably below Carnival’s largest ships, which run 181,808 to 183,521 tons carrying approximately 5,282 guests across 19 decks.
The gap is about a thousand people. Roughly 4,000 against 5,282 is the difference between a busy ship and a very busy one, and it shows up in the queues rather than in the deck space. For a lot of travellers this class is the sweet spot: enough ship to have everything, not so much that you spend the week in a line.
Where it loses. If you specifically want what Carnival built most recently, the newest attractions are on the larger ships. The Vista class is a strong general answer rather than the answer to “show me the newest thing”.
How the numbers here should be read
Gross tonnage measures enclosed volume rather than weight, which is why it is the standard for comparing ships. The guest counts in this article are written as approximate on purpose: our source records a capacity for each of these hulls without specifying whether it counts two per cabin or a fully sold ship, so presenting them as double-occupancy figures would overstate what we actually know.

Common questions
How many Vista-class ships are there?
Five: Carnival Vista (2016), Carnival Horizon (2018), Carnival Panorama (2019), Carnival Venezia (2023) and Carnival Firenze (2024).
Which Vista-class ship is the biggest?
Carnival Venezia at 135,225 gross tons, carrying approximately 4,208 guests — the largest capacity in the class. Carnival Firenze is close behind at 135,156 tons.
Are the Vista-class ships identical?
No, and this is the class where that matters most. Carnival Firenze runs to 18 decks; Carnival Vista, Horizon and Panorama have 15 and Carnival Venezia has 14. Never assume a deck count from class membership here.
What is different about Carnival Venezia and Carnival Firenze?
They joined the class later, in 2023 and 2024, and they are the two largest hulls in it by tonnage. They also carry the highest guest counts in the class at approximately 4,208 and 4,126.
How does the Vista class compare to Carnival's Excel class?
An Excel-class ship is 181,808 to 183,521 gross tons carrying approximately 5,282 guests across 19 decks. A Vista-class ship is roughly three-quarters the tonnage with about a thousand fewer guests, which usually means shorter queues at the popular venues.
The Vista class is the most quietly varied group of ships Carnival runs, and the one where the class name does the least work. Two of the five are meaningfully different vessels from the other three, and a guide that tells you otherwise has not checked.
