Bitmap Screen Fonts

Font vendors should create bitmap screen fonts to accompany their printer fonts. Screen fonts should be created for the aspect ratios of each of the popular display device classes. Minimally, a vendor should supply line sizes that match the frequently used graphic arts point sizes (that is, 8, 9, 10, 12, 14, 18, and 24). Screen fonts are measured in line sizes (lines-per-inch) rather than typographic point sizes. Specific line sizes of the fonts may be different from their nominal point sizes.
