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
The Scientific and Technical Information eXchange (STIX) fonts are intended to satisfy the demanding needs of authors, publishers, printers, and others working in the scientific, medical, and technical fields.
The STIX Two fonts consist of one Math font, two variable text fonts (Roman and Italic), and eight static text (Regular to Bold in both roman and italic variants). Together, they provide a uniform set of fonts that can be used throughout the production process.
The STIX project began through the joint efforts of American Mathematical Society (AMS), American Institute of Physics (AIP), American Physical Society (APS), American Chemical Society (ACS), The Institute of Electrical and Electronic Engineers (IEEE), and Elsevier. These companies are collectively known as the STI Pub companies.
