About Source Serif 4

Source Serif 4 de Frank Griesshammer é a evolução madura da família Source Serif, a serifa companheira da Source Sans da Adobe, refinada ao longo de versões sucessivas em uma serifa transicional matizada com eixos variáveis de tamanho óptico e peso. O eixo opsz permite que a typeface ajuste automaticamente os detalhes das formas de letras conforme o tamanho muda — ampliando o espaçamento e abrindo as aberturas em tamanhos pequenos, apertando as proporções e aumentando o contraste em tamanhos de exibição. O suporte a Cirílico, Grego e Vietnamita a torna uma typeface global capaz para sistemas editoriais, documentação técnica e livros digitais.

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.
