FAQPage Schema
How do I calculate line-height for text in a grid-aligned design system?▼

Grid-aligned line-heights ensure visual harmony and readability by matching text spacing to your design system's grid. You calculate the appropriate line-height by using the font size and the specific grid system in use.

What is the difference between UI and prose line-heights in a grid system?▼

A two-track model differentiates UI and prose line-heights to handle various content types within a grid system. UI tracks optimize compact interface components, while prose tracks enhance long-form text readability.

How do I ensure design consistency with a 4/8 spacing grid for typography?▼

Design consistency with a 4/8 spacing grid requires calculating line-heights that strictly align with these grid increments. This enforces vertical spacing rules so typography harmonizes with the overall layout.

Can I use a grid-aligned line-height approach for both UI components and prose content?▼

Yes, a grid-aligned line-height approach applies to both UI components and prose content. It uses distinct line-height tracks to accommodate the different visual and readability requirements of each content type.

What do I need to know before calculating grid-aligned line-heights for my UI?▼

Before calculating grid-aligned line-heights, you must know the specific font size and the grid system in use, such as a 4/8 grid. This prerequisite knowledge ensures the calculated spacing aligns correctly with the layout.

Why does my typography spacing break visual harmony in grid-aligned design systems?▼

Typography spacing breaks visual harmony in grid-aligned design systems when line-heights do not match the grid increments. Calculating line-heights based on the font size and grid system restores vertical rhythm and readability.
