FiraGO 1.0 * NEW *

  • 15 weights, 2 styles (Roman & Italic)

New family name

For several reasons, we decided to establish FiraGO as a new product. That way users of FiraSans can also install FiraGO without any conflict.

Script support

Identical to Fira Sans 4.3:

  • Latin Extended
  • IPA
  • Pan African
  • Cyrillic Extended (+ locl BGR and SRB)
  • Polytonic Greek

Additionally in FiraGO:

  • Arabic
  • Devanagari
  • Georgian
  • Hebrew
  • Thai

Technical improvements

  • Manual basic True Type Hinting via Glyphs

Please also see the pdf comparison document.

Future prospect

  • All upcoming extensions will be based on FiraGO.
  • Fira Sans version 4.3 will be the last version for the time being.
  • Math? Mono extension? Mono Italic? Serif? Slab? FiraGO Condensed? Broader script support? …
  • It’s up to you. We’re looking for extension funding and expert’s consultancy.

* Note on thin weight fractional coordinates

As for that, these weights should be seen as an experiment by now. If you notice any problems in smaller sizes please consider to use weights from Thin.
