Find your
type.
Browse every font in the T3 Code picker. Read each typeface’s story, compare letterforms and measured dimensions, and star favorites. Stars and saved views can sync between your computer and phone.
Stars, saved views, and weight sync through a private GitHub Gist in your account. Create a token with only the “gist” scope, paste it here once, then use “Phone setup link” to connect your phone.

Data sources & measurement notes
Dimensions were measured locally with CoreText at 16 points in each regular face. Cap height is the font's uppercase height; sentence width uses “The quick brown fox jumps over the lazy dog.” Browser rendering can differ. Relative width is sentence width divided by cap height, so it compares widths independent of size; the “Narrow / condensed” style uses it (below 23.5) plus width class and family names. Families without complete A–Z coverage and symbol faces have no English dimensions; their English specimens may use fallback.
“Year” uses a typeface inception date from Wikidata when available. Otherwise it is the earliest year in the installed font file's copyright notice, which does not establish the original design date. Font descriptions, histories, and classifications were researched from the linked sources (mostly Wikipedia and foundry pages); each font’s “About” panel lists them. Tier measures family breadth: S = 8+ faces, A = 4–7, B = 2–3, C = 1. It is not a quality score.
On devices without a font installed (for example a phone), the gallery shows a pre-rendered image of the Mac rendering, drawn at regular weight, instead of a fallback font.
PCA uses eight standardized 16-point measurements across Latin-oriented families with complete English letter coverage. The chart projects their geometry onto the first two principal components; nearby points have similar measured proportions, not necessarily similar visual style.
