Frequently Asked Questions

What line-height reads best?

1.5–1.7 for body text, 1.1–1.3 for display headings. A 32px hero at 1.2 with 600 weight previews exactly — copy the values when it looks right.

When do I adjust letter-spacing?

Positive tracking (+0.05em) for uppercase labels and eyebrows; negative (−0.02em) for large headlines. Body copy almost always stays at 0.

How do I pair the preview with my stack?

Match the preview family to your loaded webfont first — metrics differ per family. Then copy size, height, spacing, and weight as one CSS block.

Does preview text leave the browser?

No — preview renders locally in your browser. Nothing leaves your device.
