Regular · 20/30 px

Ledger Mono gives every character the same width, so columns line up in code, invoices and data tables without a single tab stop. Similar shapes are pulled apart: zero and capital O, one, lowercase l and capital I. Five weights let you set comments light and keywords bold.

About Ledger Mono

Round typewriter keys with black letters above a rainbow-colored fan
Ledger Mono started as lettering for typewriter key caps.

Ledger Mono is sold as one family: five weights from Light to Bold, all fixed width. Code editors, terminals and spreadsheets use the desktop license; dashboards and documentation sites use the web license.

Version 1.1 made the slashed zero a feature you can switch on everywhere, added an alternate ampersand and at sign, and tightened the spacing of the punctuation so => and != read as single symbols.
