About
Cardo was designed specifically to meet the needs of classicists, biblical scholars, and linguists, with extensive support for ancient scripts, polytonic Greek, and a wide range of diacritics. Its clean, legible forms hold up well in long-form body text, particularly in academic journals, critical editions, and digital humanities projects. It is one of the more principled and purposeful text faces available on Google Fonts.
Classification
Cardo is a scholarly humanist serif designed for classical and multilingual academic publishing, with careful attention to Greek, Latin, and extended Unicode character sets. Its modestly high contrast and open apertures prioritise readability in dense scholarly text.
