To further define the capacity for special interest groups, additional tags can be used to describe them in addition to the tag capacity=*:

Key Value Apply to Description
capacity number node area The amount of lots, rooms, seats (or the like) available. (Including all special lots, e.g. parking spaces for disabled drivers)
capacity:disabled=* yes/no/number node area Defines whether or not dedicated lots, rooms, seats or other spaces for the disabled are available. If known, the number of spaces can be specified. See more...
capacity:women=* yes/no/number node area Defines whether or not dedicated lots, rooms, seats or other spaces exclusively for women are available. If known, the number of spaces can be specified.
capacity:men=* yes/no/number node area Defines whether or not dedicated lots, rooms, seats or other spaces exclusively for men are available. If known, the number of spaces can be specified.
capacity:parent=* yes/no/number node area Mostly parking areas: Defines whether or not dedicated parent and child parking spaces are available. If known, the number of spaces can be specified.
capacity:baby=* number node area Mostly playground equipment: Defines how many spaces (out of total capacity=*) are dedicated for small babies. Avoids ambiguity of baby=*.
capacity:charging=* yes/no/number node area Defines whether or not dedicated charging spaces are available when used with amenity=parking. If known, the number of spaces can be specified. capacity=* should be used in conjunction with amenity=charging_station.
capacity:truck=*
capacity:bus=*
capacity:motorcar=*
capacity:cargo_bike=*
capacity:motorcycle=*
yes/no/number node area A transportation mode (a.k.a vehicle category) can be added as subkey to mark the number of trucks or buses a parking lot can accommodate.

Or, e.g. in bicycle parking, number of spots, designed explicitly for cargo bikes.

capacity:persons=* number node area Defines how many persons can be carried, used for example together with highway=elevator. If it's obvious that the maximum number of persons of a feature is meant, just use capacity=* for it.
capacity:persons=*
capacity:caravans=*
capacity:tents=*
capacity:pitches=*
capacity:beds=*
capacity:rooms=*
number node area On campsites capacity=* is ambiguous thus use the suitable subkeys to distinguish between number of persons and number of pitches. For a tourism=guest_house you may use Simple_Indoor_Tagging.
capacity:pupils=*
capacity:teachers=*
capacity:classrooms=*
number node area Undocumented keys - Number of pupils/students and teachers a school is built for. Almost all occurrences are from few imports of data.
capacity:standard=*
capacity:long=*
number node area Defines the capacity of small / large vehicles when used with amenity=parking. if used with highway=services, highway=rest_area use parking:capacity:standard=*, parking:capacity:long=*.
