readability-rhythm-and-prose

Apply paragraph rhythm and prose-level readability — calibrating leading, paragraph spacing, subheading frequency, and visual breathing room so that long-form text reads smoothly without fatigue. Use when designing article layouts, documentation, reports, transcripts, or any context with sustained prose. Beyond line length and legibility, the rhythm of prose layout — the rest points provided by paragraph breaks, the hierarchy provided by subheadings, the breathing room provided by margins — determines whether readers stay engaged with long content.

# Readability — rhythm and prose

Beyond line length, readability is determined by the rhythm of prose layout: the spacing between lines, the spacing between paragraphs, the frequency of subheadings, the visual breathing room around the text. Together these create a reading experience that either flows or stutters, that either invites continued reading or discourages it.

The right rhythm makes long content feel approachable. The wrong rhythm makes the same content feel like a wall.

## Leading (line height) for prose

Leading is the vertical space between baselines of consecutive lines. For body prose:

**1.5× to 1.7×** the font size is the comfortable range. So 16px text needs 24–28px line height; 18px text needs 27–31px line height.

Why this range:
