The key width describes the actual width of a way or other feature. By default, values will be interpreted as metres. To reduce the risk of misunderstandings, or if the width 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.
The source of the width information can be specified by source:width=*.

Examples
| Width | Tagging | Remark |
|---|---|---|
| Two metres | width=2 | Alternatively width=2 m could be used. |
| 0.6 miles | width=0.6 mi | Please note the dot as decimal separator! |
| 16 feet and 3 inches | width=16'3" | Use a typewriter apostrophe character after the feet value and a typewriter double-quote character after the inches value. Spaces are not permitted. |
Common mistakes
Legally restricted width
Do not confuse the specification of the actual width with the specification (of a legal restriction) of a maximum permissible width of vehicles via maxwidth=*.
Descriptive values
It is discouraged to specify values as, e.g., width=narrow or similar. See therefore this proposal.
Estimated values
If the width couldn't be exactly determined or is estimated, use the key est_width=* instead.
Incorrect values
Often the values themselves are not specified correct. The following table contains examples of incorrect tags and their correct notation.
| Incorrect | Explanation | Correct |
|---|---|---|
width=2km
|
The space between value and unit is missing. | width=2 km |
width=0,6
|
The comma is used as wrong decimal separator. | width=0.6 |
width=12' 6"
|
There should not be a space between feet and inches. | width=12'6" |
