Impact is a realist sans-serif typeface designed by Geoffrey Lee in 1965 and released by the Stephenson Blake foundry of Sheffield. It is well known for having been included in the core fonts for the Web package and distributed with Microsoft Windows since Windows 98. More recently, it has been used extensively in image macros.
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 three-quarters the capital line. Ascenders are short, and descenders even shorter. With narrow apertures and folded-up letterforms, the lower-case can be quite hard to read printed small, especially for people with vision problems. The face is intended for headlines and display use rather than body text. As a display design, it was not released with an italic or bold weight.
Impact resembles other condensed designs of the period, including the Letraset face Compacta and Linotype’s Helvetica Inserat, as well as Haettenschweiler which is similarly designed, but narrower. It is also quite similar to the masthead of Private Eye (which is caps-only), designed by Matthew Carter slightly earlier. Writing in 2004, the year before his death, Lee explained that the design goal was "to get as much ink on paper as possible in a given size with the maximum possible x-height" and to provide a home-grown alternative to European designs in this style, which were complicated for British businesses to license and use. Lee was an advertising design director and designed Impact with posters and publicity material in mind. It was initially promoted with a brochure (shown below right) titled 'The Impact of Impact'.
Released at the end of the age of hot metal typesetting as phototypesetting gained popularity, it would be Stephenson Blake's penultimate typeface released in metal. The design rights were acquired by Monotype, which ultimately licensed the design to Microsoft as part of a package of fonts for use with Windows in the 1980s and 1990s.
The original design contained a number of alternate characters for the letters J and r, intended for letter positions at the start and end of words, which have generally not been included in digitisations. The common digitisation also simplifies the design considerably, omitting the subtle bevelling of dots on 'i' and 'j' and flared stroke ends seen on the original metal type release. An eccentricity preserved in the digitisation is the ampersand, which is only as high as the x-height, not the cap height.
Lee himself released the variant Impact Wide from his original drawings in 2002 for online sale. This release includes the stylistic alternates and an italic design.
In July 2010, Ascender Corp introduced an enhanced version of Impact. While based on the original digitisation, it included extensive OpenType typographic features designed by Terrance Weinzierl and Steve Matteson, which included quirky interlocking characters, text figures and proportional and tabular figures.
