Implementation
Why have a custom typeface in a brand identity?
A custom typeface can give a brand a consistent visual voice beyond the logo. Sigil includes one in its Book. Use it for the roles it handles well, then check readability, coverage and the delivered font files.

Type appears more often than the logo
A headline, interface label and paragraph all carry the company’s voice. Their shapes, spacing and weight affect how the product reads. A typeface can make those applications feel related even when the logo is absent.
Distinctive type still needs a clear role. A narrow display face may work for a short verdict and struggle in a long paragraph. Do not assume one expressive font should carry every part of the site.
Check the actual glyphs and uses
Try the company name, product names, numbers, punctuation and a representative paragraph. If the product serves several languages, test those languages explicitly. The word “custom” does not establish complete language coverage.
Review the delivered license and font formats. A website needs a web-appropriate file and sensible loading behavior. A slide tool may need a different format. Keep a useful fallback when the font has not loaded.
Give the team a type hierarchy
Document which family carries display text, body text and labels. Include sizes or relationships that work at real screen widths. The hierarchy matters more than using the custom font in every place.
Sigil’s own Book demonstrates this separation: its display identity and long-form text use different roles. Apply the same discipline when implementing your own brand.
Common questions
- Does Sigil’s Book include a typeface?
- Yes. The Book offer includes a custom typeface made by Sigil’s foundry.
- Should I use the custom font for every paragraph?
- Use the roles defined by the identity and test readability. A display face may belong only in short, larger text.
