Hack Typeface Design

Hack is a monospaced typeface that is designed to optimize the display of source code text.

Primary Design Targets

• ASCII glyph set (used to display the body of all source code text)
• font sizes between 8 - 14 px
• cross-platform, cross font renderer support on Linux, OS X, and Windows operating systems
• desktop text editor text displays
• terminal emulator text displays
• website text displays
• print text displays

Primary Design Optimizations

• legibility - establish differences in the appearance of similar glyph shapes so as to properly identify different Unicode code points
• readability - glyph shape and spacing optimizations to improve the capacity to read character-character, word-word, and code block-code block combinations in source code
• visual semantics - establish semantic commonalities for glyphs used in source code text and create common visual designs within these semantic groups

Secondary Design Targets

• All glyphs outside of the ASCII set (including extended character sets used for the display of comments in source code)
• All font sizes outside of the primary design targets
• All forms of text display outside of the primary design targets
