Explanation of building height tags

For marking height top part of building (building=*) or part of building (building:part=yes) above ground level we use tag height=*. If building or part of building starts not from the ground level, we should use tag min_height=* for describing height of bottom part of building or part of building. By default meaning is counted in meters.

If you know number of levels of building or part of building above the ground level, it is also useful to add tag building:levels=* (and building:min_level=*, if the bottom level of building or part of building is not located on the ground).

Minimum height of people to use the feature

Some facilities (e.g. ski lifts, theme park rides) have a "minimum height requirement", as in "You must be X m tall to use it". min_height=* could be used to record this information. As of 5 June#32;2019 it's unknown if this is tag is used this way. See also: min_age=*, max_age=*, suggestion on the talk-gb mailing list.
