Better Typography

Great typography

Good typography is mostly restraint. A sensible scale, comfortable spacing and enough contrast beat any clever effect. A label, a table cell, a marketing headline and an article paragraph should not share one set of rules. Apply these principles when building or reviewing anything with text in it.

When reviewing, read the page instead of scanning the code: squint to check the hierarchy holds, read one full paragraph for comfort, and resize the viewport to catch bad wrapping, widows and truncation at real content lengths.

The words themselves (button labels, error messages, empty states) are covered by the better-writing skill; semantic heading structure by better-accessibility; spatial RTL layout and logical CSS properties by better-layout; rendered-pair contrast measurement and color remediation by better-colors. This skill owns how text renders, wraps, and behaves in mixed-direction content.

Write every fix in the project's own idiom: the styling system already in use, never a second one alongside it. The cheat sheet maps each declaration to its Tailwind equivalent.

Core Principles

1. Serve the Right Format

Use .woff2 (Brotli compression, broadly supported) on the web. .woff is a fallback only for very old browsers; .ttf and .otf are raw desktop formats with no web compression. How the files are loaded is the project's own concern, this skill does not prescribe it.

2. Properties Over Raw Tags

When a CSS property exists, use it. font-weight: 650 instead of font-variation-settings: "wght" 650, font-optical-sizing: auto instead of "opsz", font-variant-numeric: tabular-nums instead of font-feature-settings: "tnum" 1. Properties keep working when a non-variable fallback renders. Reserve the raw-tag properties for custom axes ("GRAD" 80) and niche features ("ss01" 1) that have no property of their own.

3. Load Intended Weights and Styles

Browsers may synthesize a requested weight or style that the active family does not provide. Prefer loading the faces the design actually uses. Set font-synthesis: none only after verifying that every required bold, italic, small-cap, superscript, and subscript form remains visually distinct across the complete fallback stack; disabling synthesis is not a diagnostic and must not erase emphasis.

4. Fewer Fonts, Sizes and Weights

Rarely use more than three fonts. Weight and size define hierarchy, but overusing them hurts readability quickly. Pair for contrast, not similarity: a serif headline with a sans body reads as deliberate, two near-identical sans-serifs read as a mistake. Below 18px, stay at weight 400+; weights under 300 are display-only (28px+), they disappear at text sizes.

5. Use a Type Scale with Semantic Names

Define a small set of sizes and deviate from it as little as possible. Hard-coded sizes without a system break down at scale. For solo projects, default names like text-sm work fine as long as the usage rules are clear. On a team, name sizes by use (text-body-sm), not by size, so the rules stay consistent.

6. Heading Sizes Descend with Level

Within a coherent page hierarchy, map heading levels to descending steps of the type scale: a visually subordinate heading should not accidentally overpower its parent. Adjacent levels may share a size toward the small end of the scale as long as weight or spacing keeps them distinct. Pick semantic heading elements according to better-accessibility; this skill controls only their visual treatment.

7. Line-Height by Role

Headings tighter, around 1.1. Body copy 1.5 to 1.6. Prefer unitless values so line-height scales with the font size; fixed values like 24px do not. Tight line-height is for short text: anything that wraps to three or more lines needs at least 1.4, even in height-constrained rows.

8. Letter-Spacing by Size

Large headings often look better with slightly negative letter-spacing. Small uppercase labels need a little positive letter-spacing so letters do not feel crowded. Body copy at reading sizes needs neither.

9. Cap the Measure

Long lines make it hard for the eye to find the next line. Cap long-form text around 60–75 characters per line. Any unit works; what matters is that a cap exists and the resulting line length sits in range. Unit choices and the pixel equivalents.

10. Wrap Deliberately

text-wrap: balance distributes text evenly across lines: use it on headings. text-wrap: pretty avoids leaving a single short word on the final line: use it on descriptions. Skip both in long-form text. overflow-wrap: break-word where long words, links or IDs could escape the container. white-space: nowrap on labels and badges where a line break looks broken.

11. Tabular Numbers on Changing Values

Digits have different widths by default, so timers, counters and prices shift layout as they update. Apply font-variant-numeric: tabular-nums to any value that changes.

12. Truncate Without Losing Content

Single line: text-overflow: ellipsis with overflow: hidden and white-space: nowrap. Multiple lines: line-clamp. Truncation hides content, so if the missing text matters, keep the full value reachable in a tooltip or expanded view.

13. Write Copy Naturally, Style with CSS

Store text in natural case and control presentation with text-transform, so redesigns never require rewriting copy. Use smart punctuation: curly quotes in prose (straight quotes in code), an en dash for ranges like 2010–2020, an em dash to set off a thought, the single ellipsis character,   to keep values like 16 px together and ­ to control where long words may break.
