This project is a type specimen of Avenir, inspired by Adrian Frutiger’s humanistic approach to geometrical precision in designing this classic typeface. Frutiger began by crafting the letter ‘O’ first, by hand, which appears to be an optically perfect circle from afar but made slight tweaks to certain angles such that it is in fact an imperfect circle. The rest of the letters and symbols were then designed based on the geometry of the letter ‘O’. The type specimen combines mathematical elements with the human touch of “fill in the blanks” worksheets as a tribute to its design methodology.
