According to ISO 15008, fonts used for in-car displays should not be too narrow or too wide.
To ensure legibility of this font on in-car information systems, it is recommended that the spacing falls within the following values:
-
space between vertical strokes (e.g. "ll") should be 150%-240% of the stem width.
-
space between diagonals and verticals (e.g. "vl") should be at least 85% of the stem width.
-
diagonal characters should not touch (e.g. "vv").
(Note that passing this check does not guarantee compliance with ISO-15008.)
