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.

SIL International recently released three typefaces for lesser-served writing systems (Tai Viet, Yi, Lepcha) used in Asia. SIL has also created Andika, which is specially designed to maximize legibility for new readers.
SIL and lesser-served languages
SIL International has a team of type designers who specialize in creating typefaces for lesser-served or non-dominant language communities. These are communities that exist alongside larger, more prominent language communities such as Chinese, English, or Arabic. These relatively smaller communities may have their own script, or they may have sounds in their language that are not represented in the script used by the majority language. Some non-dominant languages are endangered. According to UNESCO, about 40% of the estimated 7,000 languages are at risk of extinction.
Without typefaces, these language communities can't survive online.
