Have you ever wondered how many people could fit on every cruise ship in the world? What if we added up just how many people it would take to fill every berth on every ship?

It might seem like a useless exercise, but I’m a curious person. So, once the thought entered my mind, I just had to figure out what the maximum capacity would be of every cruise ship in the world if added all together.
With cruise lines building more and more ships that can carry more people than ever, I wanted to see the actual numbers.
The data below was compiled from available data on cruise ship capacity, crew counts, and which ships are both currently sailing and about to be launched within a year.
What ships were included in this list?
This list includes some cruise ships that are due to come out later this year or in 2024. This was done so the information will still be relevant over the next couple of years at least.
River cruise ships were excluded from the count, in addition to some small yacht companies with very few vessels.
The total count includes both passengers and crew, but you can see the separate numbers below as well.
In total, the passenger and crew capacity from 325 cruise ships and from 36 cruise lines were used to compile this data. There are a few other ships that could have been included but this sum represents all the major cruise lines currently operating with a few single-ship operators as well.
All of the cruise lines and how many ships were included with each line can be seen in the data below.

What capacity numbers were used?
Cruise ships generally do not sail at maximum capacity but rather at full capacity. The difference is that max capacity means that every berth on a ship is occupied.
Full capacity usually means double occupancy. This is why you will see that some cruise ships will sail at 110% capacity or more, meaning that some staterooms have more than 2 passengers. Since the goal of this task was to see how many people could fit on every cruise ship in the world, max capacity was used for the totals.
What is the total capacity of every cruise ship in the world?
After adding up the max capacity of every cruise ship on our list the total number of people would be 1,102,209.
Out of this number the total number of passengers would be 824,706.
The total crew count totals 277,457.
The 3 cruise lines with the most passengers + crew capacity are as follows:
- Royal Caribbean International:
- Passengers at max capacity: 124,374
- Crew: 39,543
- Total onboard (passengers + crew): 163,917
- Ships: 28
- Carnival Cruise Line:
- Passengers at max capacity: 103,318
- Crew: 31,809
- Total onboard (passengers + crew): 135,127
- Ships: 27
- MSC Cruises:
- Passengers at max capacity: 97,868
- Crew: 29,623
- Total onboard (passengers + crew): 127,491
- Ships: 23
*Remember this includes some cruise ships that are yet to be launched this year and into 2024.
These numbers mean that Royal Caribbean alone will account for 14.91% of all people on a cruise ship after the debut of its newest ships in 2023-2024.
If the total of 1,102,209 people were equated to the population of a U.S. city it would be the 10th largest city in the U.S, right behind Dallas, Texas.
Even if we just took the total number of cruise passengers on every cruise ship in the world, the 824,706 passengers would equate to the 17th largest U.S. city just behind Charlotte, North Carolina.
