height describes the actual height of a feature. By default, values will be interpreted as metres. If the height should be specified in a different unit, the unit can be added to the end of the value, separated by a space (see Examples). The value should always use the dot as decimal separator, if needed.
For ways or areas in which height varies, a average height can be specified.
The source of the height information can be specified by source:height=*.
|Four metres||height=4||Alternatively height=4 m can be used.|
|1.35 metres||height=1.35||Please note the dot as decimal separator!|
|7 feet and 4 inches||height=7'4"|
Height of buildings
For buildings not the average height, but the maximum height will be specified, i.e. the height of the top edge of the building (excluding antennas, spires and other equipment mounted on the roof) from the lowest terrain point at the building.
The height of individual parts of buildings can be specified using building:part=*. For further details see there.
Elevation above mean sea level
Legally restricted height
Do not confuse the specification of the actual height with the specification (of a legal restriction) of a maximum permissible height of vehicles via maxheight=*.
Often the values themselves are not specified correct. The following table contains examples of incorrect tags and their correct notation.
||The space between value and unit is missing.||height=4 m|
||The comma is used as wrong decimal separator.||height=0.8|
||There should not be a space between feet and inches.||height=11'4"|
