Wayfinding requires designers to organise and communicate the relationships of space in the environment. Basically, it is the naming and marking of places, identifying destinations, and providing directional information. The Cooperative Research Centre for Construction Innovation produced a comprehensive, if somewhat technical, set of wayfinding design guidelines.
The guidelines covers basic principles, and very detailed design solutions and strategies, covering topics such as arrival point, main entry, internal arrival point, graphic communication, restrooms and toilets, lifts, and signage design. Sign legibility, system design criteria, and viewing distance to signs are all covered, plus much more. Wayfinding is a key element of accessibility for everyone. Making signs and systems universally designed for everyone requires additional thought and planning.
AS 1428.4.2 Wayfinding Standard, was published in 2018 by Standards Australia.
Editor’s Note: I’ve come across a designer or two who consider signs and signage an imposition on their design and try to minimise their use or placement. This picture shows how one designer thought that disguising signage was a good idea. Architectural wayfinding strategies minimise the need for lots of signs.
