The TeX Gyre Heros family of sans-serif fonts is based on URW Nimbus Sans L. The original font, Helvetica, was prepared by Max Miedinger (with Eduard Hoffmann) in 1957 at the Haas type foundry.

The standard faces of Heros have been greatly extended, and contain nearly 1200 glyphs each. The family is available both in Adobe Type 1 and in OpenType formats, and LaTeX support (for use with a variety of encodings) is provided. Vietnamese and Cyrillic characters were added by Han The Thanh and Valek Filippov, respectively.

TeX Gyre Heros is distributed as part of the TeX Gyre collection.

The authors are Bogusław Jackowski and Janusz Marian Nowacki.
