How is the space ratio on a cruise ship calculated?

The space ratio on a cruise ship is calculated by dividing the ship's Gross Tonnage (GRT) by the number of passengers. This metric is significant as it provides an indication of the amount of space available per passenger on a cruise ship. A higher space ratio generally suggests more spacious accommodations and amenities, enhancing passenger comfort and experience onboard. The Gross Tonnage measurement reflects the overall internal volume of the ship, which includes all usable and sometimes non-usable spaces, thus giving a comprehensive view of how much space is available to be shared among passengers.

Using this method allows for a standardized comparison between different ships, making it easier for travel agents and customers to assess the cruising environment. Other options like simply looking at the number of cabins or the ship's dimensions do not accurately reflect the relationship between the total space and the number of individuals onboard, which is crucial for understanding passenger comfort.
