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.

/* Please select at least one weight and style */ Background & Story
Iansui is based on Fontworks' Klee Semibold font, which is a script font handwritten by pencil or pen. Its quiet design has an elegant and slightly feminine look that sets itself apart from traditional script and textbook fonts. Ideal for body text. Iansui further modifies the existing design to meet the Ministry of Education's requirements for Taiwanese use.
