Frequently asked questions
Should letter-spacing be positive or negative?
Positive for uppercase and small text, negative for large display headings. Body text is usually 0.
Why use em instead of px?
em scales with font-size automatically, keeping the visual tracking consistent across responsive breakpoints.
How much letter-spacing for headings?
Large headings often use -0.02em to -0.04em. All-caps text usually needs +0.05em to +0.1em.
