The Misunderstood Usefulness of `font-size-adjust`

2025-07-26

This article challenges the common misconception surrounding the CSS property `font-size-adjust`. The author argues that `font-size` specifies the size of the box around a glyph, not the glyph itself, leading to inconsistencies across different fonts. Instead of solely focusing on font fallback, `font-size-adjust` can be used to ensure more consistent sizing across various fonts on a page. The author recommends setting it to `ex-height 0.53` in a CSS reset for improved typographic consistency.
