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.
