Good typography guides attention, improves understanding, and makes communication effortless.
The Anatomy of a Typeface
By FontSide · June 2026
Every typeface is a system of decisions — about stroke contrast, x-height, spacing, and rhythm. The best ones feel invisible: you stop seeing the letters and start hearing the voice behind them. That transparency is the hardest thing to design.
A high x-height opens up the counters and makes small text breathe. Tight tracking pulls a headline together; loose tracking gives a caption room to exhale. None of these choices are accidents — they are arguments about how reading should feel.

This project provides Bopomofo (Zhuyin) enabled variants of Traditional Chinese typefaces, implementing the Bopomofo IVS Font Specification (bpmfvs) developed by ButTaiwan and particularly intended for use with buttaiwan.github.io/bpmfvs/.
Unlike traditional Bopomofo fonts that require separate font files for different pronunciations, these fonts utilize Ideographic Variation Sequences (IVS) and GSUB features to support polyphonic characters within a single font file. This allows users to seamlessly add pronunciation guides while maintaining the same typeface.
