Jura Book by Daniel Johnson is a free geometric sans serif with slim, even strokes and broad, open proportions. Rounded corners soften the squared construction. The tall lowercase forms and gently curved joins keep the lettering distinctive.
Its clean contours echo simple line illustrations and technical diagrams, making it useful for science publishing, museum graphics, and software branding. The same controlled geometry links those settings with exhibition signage and product packaging for a precise, approachable voice.
