Wayfinding signage has a strange property: when it's done well, nobody notices it - visitors just seem to know where they're going. When it's done poorly, it's the first thing people complain about, whether that's a patient lost in a hospital corridor or a new employee wandering an office floor looking for a meeting room.

The starting point isn't the signs themselves, it's the journey. Before designing any wayfinding system, map out the actual paths people take from entrance to their likely destinations - reception to consultation rooms in a clinic, entrance to classrooms in a school, lobby to departments in an office. Signage should appear at every decision point along that path, not just at the destination.

Consistency matters more than cleverness. A wayfinding system that uses the same colour coding, icon style, and directional arrow format throughout the building is far easier to follow than one where each sign looks slightly different. This is why hospitals often use colour-coded paths ("follow the blue line to Radiology") - it turns navigation into pattern recognition rather than reading.

Hierarchy needs to be visual, not just informational. Primary directional signs (which floor, which wing) should be more prominent than secondary signs (room numbers, department names), which should be more prominent than tertiary signs (individual office nameplates). If everything is signed at the same visual weight, people struggle to know what to look at first.

Accessibility isn't optional in most public-facing wayfinding, particularly in healthcare and education settings. Braille and tactile lettering on room signs, sufficient text-to-background contrast, and text sized appropriately for the viewing distance all matter both for genuine usability and, in many cases, for compliance requirements specific to your facility type.

Materials should match the environment's traffic and cleaning needs. High-traffic corridors in hospitals benefit from durable, easy-to-clean acrylic or laminate signage that can handle frequent disinfection. Office wayfinding has more flexibility and can lean into branded materials like frosted acrylic or metal that match the company's overall interior design.

Planning a wayfinding system usually works best as one coordinated project rather than ordering individual signs as needs come up - it keeps the visual language consistent and is typically more cost-effective than piecemeal ordering. Sharing a floor plan or even a rough sketch of your space, along with the main decision points visitors need help at, is the best starting point for a proposal.
