QR Code Size for Vehicle Wraps & Decals
Vehicles move. Viewers have seconds to scan. Here's how to size QR codes for cars, trucks, and vans that actually get scanned in the real world.
Quick Answer
Minimum QR code size for vehicles:
- • Parked vehicles: 8" - 12" (20-30 cm)
- • Slow traffic / parking lots: 12" - 18" (30-45 cm)
- • Highway visibility: 24"+ (60+ cm) — but realistically, don't expect scans
The Reality of Vehicle QR Codes
Let's be honest: QR codes on moving vehicles are hard to scan. They work best when:
- • The vehicle is parked (service calls, deliveries, job sites)
- • Traffic is stopped (red lights, parking lots)
- • The viewer is a passenger, not a driver
Design for parked scenarios. Highway scans are a bonus, not the goal.
Recommended Sizes by Vehicle Type
Car Door / Rear Window
8" - 10" (20-25 cm). Scannable from adjacent parking spots or sidewalks.
Van / SUV Side Panel
12" - 16" (30-40 cm). More real estate, use it.
Box Truck / Trailer
18" - 24" (45-60 cm). Visible from across parking lots.
Tailgate / Rear Panel
12" - 18" (30-45 cm). Stopped traffic can scan from behind.
Where to Place Vehicle QR Codes
- • Rear panel/tailgate: Best for stopped traffic. Drivers behind have time to scan.
- • Side doors: Great for parked visibility. Place at eye level when standing.
- • Rear window: Works if you use a simple design and short URL.
- • Avoid: Front hood, roofline, or anywhere with extreme curves.
Vehicle QR Code Design Tips
- • Maximum contrast: Black on white, white on black. Vehicle colors will fight you.
- • Quiet zone: Leave extra white space around the QR code — busy wraps need breathing room.
- • Short URLs only: Simpler QR pattern = better scanning at distance and speed.
- • Clear CTA: "Scan for Quote" or "Get Our App" — tell them why.
- • Matte laminate: Gloss reflects sunlight and kills scans.
What Should the QR Code Link To?
Vehicle scanners are on the go. Make the destination fast and mobile-friendly:
- • Contact page with click-to-call button
- • Quote request form (short, mobile-optimized)
- • Google Maps directions to your location
- • App download page
