With so many Royal Caribbean cruise ships in the fleet, it can be confusing to figure out how big each ship is by size.
Ship size isn't everything when it comes to picking the right ship for you, but how big a ship is remains one of the key metrics a lot of people pay attention to when it comes to comparing vessels.
Royal Caribbean is known for building big cruise ships. It's been their mantra since debuting the first "mega ships" in the late 1980s.
Since then, new cruise ships have rapidly grown in size. New classes of cruise ship usually bring with them even larger ship sizes.
While the size of a cruise ship is not the end-all be-all statistic that defines a ship from another, it is certainly a metric many people pay attention to, especially from a marketing perspective.
So whether you have a passing interest in knowing how big each ship is in Royal Caribbean's fleet, or want to prove your friend wrong that you know which ship is the biggest, here is a look at all the Royal Caribbean cruise ships by size.
How do you measure how big a cruise ship is?
Cruise ships are measured by their gross tonnage, which can be a confusing metric to understand.
Gross tonnage is a nonlinear measure of a ship's overall internal volume.
What?
Basically, this is a way to measure passenger vessels by volume and not weight. This is the standard way to measure how cruise ships compare to each other because of how designs can vary greatly.
