Typography for San Siro Stadium Wayfinding

Stadium signage that couldn't afford to be misread in the dark

Milan-based Leftloft studio originated LFT Iro Sans from a wayfinding commission for San Siro stadium, where legibility under poor lighting and irregular wall geometry was the primary constraint. The project expanded to address a recurring problem in public-space signage: mismatched typefaces and icon families undermining brand coherence. The solution unified a text face, a unicase display style, and a custom pictogram set into a 38-member family. Pictogram shapes were radically simplified so meaning and visual language align with the letterforms.

Insights

The original brief required readability under poor lighting and on irregular surfaces including overhangs, shaping the typeface's technical construction from the outset.
Pictogram integration was motivated by an observed failure mode: location developers mixing unrelated icon families with the text face, fragmenting the wayfinding system.
The unicase style varies hybridisation per letter — more pronounced in 'i', 'm', 't', 'd', and 'b'; more restrained in 'a', 's', 'c', and 'e'.
Text weights include two distinct oblique styles (Slanted and Italic); separate Display Ultralight and Display Heavy cuts handle headline use.
