QR Code Floor Plan Best Practices: Placement, Sizing, and Design

A QR code wayfinding system is only as good as its physical placement. A perfectly set up digital map is useless if the QR codes are printed too small, placed too high, or hidden behind a plant. Here are the practical details that matter. Need to create the map first? Start with our free indoor map maker guide.

Print size matters

The minimum recommended QR code size for wayfinding is 3 x 3 cm (roughly 1.2 x 1.2 inches). This works for scanning distances up to about 30 cm (1 foot). For wall-mounted codes that people scan from a few steps away, go larger — 8 x 8 cm (3 x 3 inches) or bigger.

A good rule of thumb: the scanning distance is roughly 10 times the QR code width. A 5 cm code can be scanned from about 50 cm away. For a code on a wall that people scan from 1 meter, you want at least 10 cm width.

Placement height

Mount QR codes at eye level: 140-160 cm (55-63 inches) from the floor. This works for most adults whether standing or in a wheelchair. Avoid placing codes above 180 cm or below 100 cm.

For elevator lobbies, the ideal spot is on the wall directly facing the elevator doors, at eye level. This is the first thing people see when the doors open, and it is a natural pause point.

Where to place codes

Place QR codes at decision points — locations where people stop and decide which way to go:

Building entrances (inside, after the door), elevator lobbies on every floor, stairwell landings, corridor junctions and T-intersections, reception and information desks, waiting areas.

Avoid placing codes in locations people walk past quickly without stopping, like the middle of a long straight hallway. People do not scan while walking — they scan when they pause. For industry-specific placement tips, see our guides for hotels, hospitals, and warehouses.

Add context to the sign

A QR code alone is not enough. Add a brief label: "Scan for map" or "Find your way" and a small phone icon. Visitors need to understand what the QR code does before they will scan it.

Keep the sign simple. The label, the QR code, and optionally your venue logo. Do not add instructions about downloading apps or creating accounts — there are none. The simpler the sign looks, the more likely people are to scan it.

Material and durability

For temporary events, printed paper works fine. For permanent installations, laminate the prints or use weatherproof adhesive labels.

For outdoor locations (parking lots, campus walkways), use UV-resistant materials or place codes under a small awning. QR codes are resilient to minor damage — up to 30% of the code can be obscured and it will still scan — but dirt, water damage, and sun fading will eventually cause problems.

Aluminum or acrylic sign holders work well for permanent installations and look professional next to existing building signage.

Testing after installation

After placing all QR codes, walk your venue and test every single one. Use at least two different phones (iPhone and Android). Scan from the distance a visitor would naturally stand. Check that the "You are here" marker appears in the correct position.

Common issues found during testing: QR codes placed behind glass that creates glare, codes in dimly lit areas where phone cameras struggle, and codes printed too small for the intended scan distance.
