About Source Serif 4

Source Serif 4 de Frank Griesshammer est l'évolution mature de la famille Source Serif, le serif compagnon de Source Sans chez Adobe, affiné au fil des versions en un serif transitionnel nuancé avec des axes variables de taille optique et de graisse. L'axe opsz permet à la police d'ajuster automatiquement les détails des formes en fonction de la taille — en élargissant l'espacement et les ouvertures aux petites tailles, en resserrant les proportions et en augmentant le contraste aux tailles d'affichage. La prise en charge du cyrillique, du grec et du vietnamien en fait une police mondiale capable pour les systèmes éditoriaux, la documentation technique et les livres numériques.

Typography Concepts

  • Measure

    The length of a line of text, typically 45–75 characters for optimal readability. Too long or too short reduces reading comfort.

  • Font Family

    A group of related fonts that share the same basic design but vary in weight, width, or style. In CSS, the font-family property specifies preferred fonts.

  • unicode-range

    CSS descriptor in @font-face that specifies which Unicode characters to download from a font file, enabling automatic subsetting by the browser.

  • font-variation-settings

    CSS property to control variable font axes directly — weight, width, slant, and custom axes. Lower-level than font-weight/font-stretch.

  • Optical Size

    Adjusting letterform details based on the intended display size. Small text needs more spacing and heavier strokes; large text can be more refined.

  • Vertical Rhythm

    Consistent spacing pattern that aligns text baselines and element spacing to a baseline grid. Creates visual harmony on the page.
