Cantarell by Dave Crossland of Abattis is a free humanist sans serif with open, upright forms and gently changing stroke widths. Broad curves and clean joins keep the lettering calm and approachable, with a practical shape that avoids both strict geometry and overt decoration.
Digital interfaces and printed editorial pages both suit its restrained construction, since the letters feel orderly without looking mechanical. It also makes a credible voice for wayfinding, educational materials, and understated branding. The friendly curves are especially well matched to public services, cultural organizations, and products aimed at a broad everyday audience.
