How many crew members are there for one passenger, and why this is important for you? This ranking will inform you about cruise ship passenger and crew capacities and help you understand how much "crew time" you can expect on which cruise ship.

The passenger-crew ratio is calculated by dividing the total number of passengers by the total number of crew members. It is a measure of the level of service you can expect during your journey. The higher the ratio, the more time each crew member has to fulfill your wishes.

It is not to be confused with the passenger-space ratio, which is the gross tonnage of a cruise ship divided by the number of guests.

Why should you check a cruise ship's passenger to crew ratio?

If comfort and excellent quality of service is a priority for your cruise vacation, knowing this will help you choose the best cruise ship for you. Although the largest cruise ships can guarantee onboard space, getting personalized service from the cruise staff is even more crucial. Many cruise lines, especially from Carnival Cruise Line, Norwegian Cruise Line and Royal Caribbean International or MSC Cruises are taking this more seriously.

As you will see in the below ranking, the biggest cruise ships in the world like Symphony of the Seas, Oasis Of The Seas, Quantum of the Seas or Harmony Of The Seas, all from Royal Caribbean Cruise Line don't necessarily offer the highest passenger to crew ratio.
