What is Line Spacing?
Also known as leading, line spacing refers to the vertical space between lines of text. It's measured from baseline to baseline. Proper line spacing prevents a cramped or irregular feeling.
Print Books vs. eBooks
For printed books, line spacing should be 120-150% of the font size. Digital books allow more generous spacing due to lower resolution, around 140% or more.
Spacing for Body Text
Body copy line spacing should offer sufficient whitespace without large gaps between lines. 1.2-1.5 times the font size is ideal for maximizing comfortable readability.
Spacing for Headers
Headers only contain a few lines, so tighter spacing is preferred. 1.1-1.2 times the font size prevents awkward gaps around titles.
Special Text Considerations
Unique text elements like pull quotes can incorporate dramatic spacing for visual flair. But use sparingly to maintain overall flow.
Proof Multiple Sizes
When proofing, preview the spacing at both actual and thumbnail sizes. The line gaps should seem natural at different scales.
Key Spacing Tips
- Allow space for ascenders and descenders to avoid collisions.
- Use consistent spacing styles across text elements.
