A typeface in the Bitstream Vera lineage

Hack has deep roots in the libre, open source typeface community and includes the contributions of the Bitstream Vera & DejaVu projects.

The face has been re-designed with an expanded glyph set, modifications of the original glyph shapes, and meticulous attention to metrics.

The Cast of Characters

Letters, punctuation, and symbols are well-balanced and easily distinguished.

The regular weight is comfortable to read at the small text sizes used for source code development.

Source Examples

Distinct Glyph Shapes

A Handful of Serifs

Strategically placed serifs improve the rhythm of the monospaced text by eliminating large gaps on each side of narrow characters and help to distinguish glyphs like the lowercase l and number 1 at small text sizes.

Weight and Spacing

The punctuation characters were designed with a heavier semi-bold weight in the regular font and are set with wide sidebearings on the side adjacent to alphabetic characters. These design strategies emphasize these important analphabetic characters and make them more apparent (or less transparent) in your code.
