The stemh attribute indicates the horizontal stem width of the font.
The stem width refers to the dominant stem of the font. There may be two or more designed widths. For example, the main vertical stems of Roman characters will differ from the thin stems on serifed "M" and "N", plus there may be different widths for uppercase and lowercase characters in the same font.
