Cruise Ships With the Best/Worst Space to Guest Ratio: 7 Cruise Lines Compared

Have you ever noticed that some cruise ships seem more crowded than others?    Ever wondered what cruise ship for each cruise line is the most crowded or least crowded based on simple math? Well, I wondered the same thing and decided to compile a list.

I compared 117 cruise ships from 7 major cruise lines to see which offered the most space based on passenger capacity and ship volume.

While many factors can have an impact on how crowded a ship may feel, there is a simple formula for figuring out the passenger space ratio.  Additionally, this allows us to compare different ships by the same metric and see how it compares with out experience on the ship.

How the passenger space ratio was calculated on our chart

The formula for the passenger space ratio is simply the gross tonnage (GT) of a cruise ship divided by the passenger capacity of that vessel  (Gross Tonnage ÷ passenger capacity).  In our list we used the standard double-capacity for each ship.  

It’s important to understand that some lines may more commonly exceed the double-capacity figures especially if it’s more usual for families to travel with that line.  Likewise, since the exact number of passengers on a cruise at any given time will be different it’s important to note that this part of the equation should be somewhat flexible.

What is gross tonnage anyway?

A common misconception is that the gross tonnage of a cruise ship is a measurement of weight.  However, it has nothing to do with weight at all.  In fact, gross tonnage is a unitless measurement of the volume or space of a cruise ship and includes all of the enclosed spaces of the vessel.  This is an important factor, as some areas of a ship’s open-air decks will not be included in the figure.

How else is gross tonnage used?

Ever wonder why some ship’s have bigger fees than others?  Well, the gross tonnage plays a factor.  The overall GT of a ship determines things like registration fees, regulations, safety rules and port dues, depending on each individual port.

Some of the largest cruise ships in the world belong to Royal Caribbean Cruises and have a gross tonnage of over 200,000. In fact, Wonder of the Seas has a massive GT of 236,857.

Other important factors

While using the passenger space ratio can be a simple way to compare ships and how crowded they may feel, it’s not a perfect measurement.  Factors like the overall flow of a ship’s design, how the programs are spaced out, the times in which various events take place, and the demographic of a ship all play a greater role in the feeling of being crowded on a cruise ship.

Additionally, depending on what you like to do on a cruise you might have a vastly different experience than someone else on the very same cruise simply based on what times you took part in different programs, shows, and meals.

So, this list is just a fun way to compare ships based on space and capacity.

I have sorted each cruise line separately so you can compare ships within a specific line, which I think personally is a more accurate way to compare how crowded a cruise ship may or may not feel.  This is simply because each cruise line handles passenger flow differently. 

At the end of the page I have also listed all 117 cruise ships in a chart so you can compare all of them at the same time.  The lists below include the following cruise lines: Carnival Cruise Line, Royal Caribbean Cruises, Norwegian Cruise Line, MSC Cruises, Princess Cruises, Celebrity Cruises, and Disney Cruise Line.

The larger the number in the right hand column the more spacious a ship may feel. At least that’s the idea. A number in the 20’s would feel crowded and cramped while a number in the high 40’s and above may feel spacious.

Disney Cruise Line ships by passenger space ratio

Note: There are two different numbers for capacity on Disney. The first number is for double capacity and the second is for maximum capacity. I thought it was important to have both since many Disney cruises have families with more than 2 occupants in a cabin.
