## About Allerta

Allerta is a sans serif that began as a signage typeface, meant to be read fast and from far away. Matt McInerney's approach, according to the official notes, was to exaggerate what is particular to each letter so that none can be mistaken for another. The specimen bears this out: the zero is slashed, the lowercase l ends in a curve, the a and q finish in small tails, and the capital I has no serifs but stands clear of its neighbours thanks to loose spacing. Strokes are firm and heavier than a typical regular weight. The family is a single Regular style with 188 glyphs in the basic Latin subset, which is a small character set, and it is not a variable font. Allerta is published under the SIL Open Font License 1.1.

## Where it works

- **Wayfinding and door signs**: Signage is the job Allerta was first drawn for: firm strokes and open spacing hold up at reading distance.
- **Labels with codes and numbers**: A slashed zero and a tailed l keep serial numbers, room numbers and part codes from being misread.
- **Slide and dashboard headings**: The sturdy single weight reads from the back of a room on projected titles and large figures.
- **Buttons and short interface labels**: Distinct letter shapes help one- and two-word labels, though the lack of a bold limits hierarchy.

## Things to know

- **One weight, no italic**: Allerta exists as Regular 400 only.
- **Small character set**: The font has 188 glyphs. French is covered except for the æ and œ ligatures, and the specimen shows no curly braces.
- **Latin subset only**: Only the basic latin subset is present; there is no Latin Extended, Cyrillic or Greek.
