OCR-A Font

OCR-A Font

In the early days of computer optical character recognition, there was a need for a font that could be recognized by the computers of that day, and by humans. The resulting compromise was the OCR-A font, which used simple, thick strokes to form recognizable characters. The font is monospaced (fixed-width), with the printer required to place glyphs 0.254 cm (0.10 inch) apart, and the reader required to accept any spacing between 0.2286 cm (0.09 inch) and 0.4572 cm (0.18 inch).
