FAQ
Why is em recommended for letter spacing?
em scales with font size, so spacing stays more consistent across responsive layouts and text levels.
When should I use negative letter spacing?
Use small negative values for tight headings or brand wordmarks, but avoid large negatives that reduce readability.
How should I handle mixed Chinese and English text?
Start with body readability first, usually around 0 to 0.03em, then fine-tune headings or English fragments separately.
Practical Tips
- Prioritize body readability first, then style headings with stronger spacing changes.
- On small mobile fonts, reduce spacing to avoid scattered characters.
- Validate across devices before release, especially for mixed language and numeric content.
