IN BRIEF | Just three typefaces make up the directional signage in 75% of all airports: Helvetica, Frutiger and Clearview.
These three font families are easy to read at a distance – see if you can spot them on your next journey.
Developed in Switzerland, Helvetica supposedly has a ‘neutral’ vibe, making it feel both vaguely familiar and comfortingly classic.
The distinctive lowercase ‘a’ stands apart from an ‘o’ – even from far away – with many other typefaces using a rounder ‘a’.
Adrian Frutiger designed the self-titled typeface for the Parisian Charles de Gaulle airport in 1975.
To match the airport’s contemporary architecture, it's characterised by protruding letter stems – particularly those like ‘l’ and ‘p’ – along with wider space for the openings of letters like ‘e’ and ‘n’.
Clearview was developed based solely on legibility at a distance, being put to use on the American interstate highway system.
Look for the larger enclosed spaces in letters ‘a’, ‘g’ and ‘e’, and for capital and leading letters that are a little higher than the rest.
