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
People read and interact with text on screens more and more each day. What happens on screen ends up being more important than what comes out of the printer. With the accelerating popularity of electronic books, type designers are working hard to seek out the ideal designs for reading on screen.
Motivated by her love for the pixel, Sol Matas designed Bitter. A "contemporary" slab serif typeface for text, it is specially designed for comfortably reading on any computer or device. The robust design started from the austerity of the pixel grid, based on rational rather than emotional principles. It combines the large x-heights and legibility of the humanistic tradition with subtle characteristics in the characters that inject a certain rhythm to flowing texts.
Bitter has little variation in stroke weight and the Regular style is thicker than a usual ‘Regular’ style for print design. This generates an intense color in paragraphs, accentuated by the serifs that are as thick as strokes with square terminals.
Each glyph is carefully designed with an excellent curve quality added to the first stage of the design, that was entirely made in a pixel grid. The typeface is balanced and manually spaced to use very few kerning pairs.
