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.

} Background & Story
Montagu Slab is a slab-serif display typeface designed by Florian Karsten. The typeface draws inspiration from 19th-century classic designs and it is available as a variable font with weight and optical size axes.
The optical size axis, which controls x-height, spacing, contrast and aperture, provides a wide range of variation – from low contrast and higher x-height version suitable for long texts, to a tight and high contrast display variant with prominent upturned tails.
