• Short answer: Digital typography is the design and arrangement of type (letters, numbers, symbols) using digital tools and fonts for screens and print. It covers font creation, spacing, rendering, and how text adapts to different devices.

  • Key terms

    • Typeface — a family of letter designs (e.g., Times).
    • Font — a specific style/weight of a typeface (e.g., Times Bold 12pt).
    • Glyph — the visual shape of a character.
    • Kerning — spacing adjustment between specific character pairs.
    • Hinting — instructions to improve font display at small sizes on screens.

  • How it works

    • Designers create vector outlines for glyphs (Bezier curves).
    • Fonts are packaged in files (OTF, TTF, WOFF) with metrics and tables.
    • Layout engines (browsers, word processors) use font metrics, kerning, and line-height to place glyphs.
    • Rendering converts vectors to pixels; hinting and anti-aliasing affect clarity.
    • Responsive rules (CSS) control size, line-length, and weight across devices.

  • Simple example

    • CSS: font-family: “Georgia”, serif; font-size: 16px; line-height: 1.5;

  • Pitfalls or nuances

    • Poor kerning/leading hurts readability.
    • Web fonts add load time and licensing concerns.
    • Different rendering engines produce subtly different results.

    • What is font hinting vs. subpixel rendering?

  • Short answer: Study how variable fonts (single font files with adjustable axes like weight or width) change reading speed, legibility, and page load times across screen sizes and rendering engines. Measure both perceptual readability (user tests) and technical performance (file size, rendering cost).

  • Key terms

    • Variable font — a font file that encodes multiple styles along continuous axes (e.g., weight).
    • Axis — a dimension of variation (weight, width, slant).
    • Glyph — visual shape of a character.
    • Rendering engine — software that draws fonts to pixels (browser or OS component).
    • Readability — ease of reading (comprehension, speed, comfort).

  • How it works

    • A single variable font contains outlines interpolated across axes.
    • Layout engines request specific axis values when laying out text.
    • Rendering converts interpolated vectors to pixels; hinting/antialiasing affect clarity.
    • File size can be smaller than multiple static fonts, reducing network load.
    • Different engines may rasterize axes differently, affecting appearance.

  • Simple example

    • Use CSS: font-variation-settings: “wght” 600; to increase weight for small screens.

  • Pitfalls or nuances

    • Some browsers/devices lack full axis support; visual consistency varies.
    • Overusing axes (extreme values) can hurt legibility.
    • Licensing and tooling for variable fonts are still maturing.

  • Next questions to explore

    • Which axes most affect reading speed (weight vs. width)?
    • How to design user tests measuring comprehension and fatigue?
