xx oo pp tt Impact compared to Helvetica
Impact is a realist sans-serif typeface designed by Geoffrey Lee in 1965 and released by the Stephenson Blake foundry. Its ultra-thick strokes, compressed letterspacing, and minimal interior counterform are specifically aimed, as its name suggests, to “impact”. Impact has a high x-height, reaching nearly to threequarters the capital line. Ascenders are short, and descenders even shorter. The face bears comparison with the similarly designed, but narrower, typeface Haettenschweiler, the Letraset face Compacta, and the Linotype face Helvetica Inserat.
