Typography is an essential part of the AEMO visual system. When used consistently, it unifies messaging and creates familiarity.

Avenir typeface

Avenir is the primary font. AEMO communications should use Avenir, including all body copy and headings.

The word Avenir means “future” in French and hints that the typeface owes some of its interpretation to Futura. But unlike Futura , Avenir is not purely geometric; it has vertical strokes that are thicker than the horizontals, an “o” that is not a perfect circle, and shortened ascenders. These nuances aid in legibility and give Avenir a harmonious and sensible appearance for both texts and headlines.

The typeface is made up of multiple weights: Light, Book, Medium, Heavy, and Black. Italicised versions are also included in the family.
