The tag describes the capacity a facility is suitable for.
- The number of vehicles a facility holds, such as amenity=parking, amenity=bicycle_parking or amenity=taxi.
- The number of visitors a facility holds, such as leisure=stadium or tourism=camp_site. However, for tourism=hotel, using rooms=* and beds=* is preferred.
- The number of children or students, an amenity=kindergarten or amenity=school can accept.
To further define the capacity for special interest groups, additional tags can be used to describe them in addition to the tag capacity=*:
