## About Aleo

Aleo is a slab serif family with rectangular serifs whose corners and joins are slightly rounded, and with only modest contrast between thick and thin strokes. In the specimen the lowercase is open and upright, the a is double-storey, and the serifs stay sturdy even in the Thin weight. Alessio Laiso designed Aleo as the slab serif counterpart of Lato, the sans serif by Łukasz Dziedzic. The family is variable on a weight axis from 100 to 900, with nine named weights and matching italics, 18 styles altogether. According to the official notes, an update in June 2023 brought the family to that size, made it variable, reworked the design and spacing, and added Vietnamese and Pan-African Latin letters. The fonts contain 675 glyphs across the Latin, Latin Extended and Vietnamese subsets and are licensed under the SIL Open Font License 1.1.

## Where it works

- **Headings above Lato text**: Aleo was made as the slab partner of Lato, so a page can use Aleo for titles and Lato for body copy with matching proportions.
- **Editorial body text**: Modest contrast and open lowercase shapes keep paragraphs readable, with italics available at all nine weights.
- **Brand systems needing a warm slab**: Rounded serif corners soften the slab structure, and Thin to Black gives a wide range for logotypes and campaigns.
- **Thin display titles**: Thin 100 keeps its slab serifs intact, which gives large light headings a distinct outline.
- **Vietnamese-language sites**: Vietnamese letters arrived with the June 2023 update and are part of the 675 glyphs.

## Things to know

- **Grew in June 2023**: The official notes say the update tripled the style count, made Aleo variable and changed design and spacing, so text set in the older version may reflow.
- **Weight is the only axis**: Aleo varies from 100 to 900 in weight only, in separate upright and italic files.
- **No Cyrillic or Greek**: Coverage is Latin, Latin Extended and Vietnamese.
