markerUnits

The markerUnits attribute defines the coordinate system for the attributes markerWidth, markerHeight and the contents of the <marker>.

If the markerUnits attribute is not specified, then the effect is as if a value of strokeWidth were specified.

Usage context

userSpaceOnUse

markerWidth, markerHeight and the contents of the <marker> represent values in the current user coordinate system in place for the graphic object referencing the marker (i.e., the user coordinate system for the element referencing the <marker> element via a marker, marker-start, marker-mid or marker-end property).

strokeWidth

markerWidth, markerHeight and the contents of the <marker> represent values in a coordinate system which has a single unit equal the size in user units of the current stroke width (see the stroke-width attribute) in place for the graphic object referencing the marker.
