Property Value

Type: System.Double
The distance from the topmost drawn pixel of the first line to the bottommost drawn pixel of the last line, provided in device-independent units (1/96th inch per unit).

Extent incorporates any graphical elements that might be present in a glyph, including decorative elements that might go outside the line height, baseline, or overhangs. This value is dependent on characters appearing on the line and is thus not used (and should not be used) to derive line spacing. It can however be used to align the top or bottom of paragraphs with graphical elements, or for hit-testing.
