Showing 6 of 6 recommendations
Print Specs01
Keep Minimum Print Dimensions of 2 × 2 cm
Smartphone cameras struggle to focus on tiny QR matrices. For cards and flyers, maintain at least 20 × 20 mm; for billboards or banners, scale proportionally to viewing distance.
Do: Follow the 10:1 scanning ratio: a code scanned from 1 meter away should measure at least 10 cm.
Don't: Don't print sub-15mm codes that frustrate customers with scanning failures.
Color Contrast02
High Dark-on-Light Contrast is Essential
Mobile scanning algorithms identify position markers based on luminance differentials. Inverted or low-contrast combinations cause severe recognition drop-offs.
Do: Keep QR dots dark (black, deep green) against a solid white or light-tinted card background.
Don't: Don't print metallic foil or glossy reflective finishes over critical QR code zones.
Call to Action03
Pair Every Code with a Compelling Benefit
Tell customers exactly what reward or service scanning unlocks. Adding a clear CTA increases scan-through rates by up to 45%.
Do: Label clearly: 'Scan to View Our Menu & Order on WhatsApp' or 'Instant WhatsApp VIP Support'.
Don't: Don't assume passersby know what your QR code links to without explicit copy.
Quiet Zone04
Preserve the 4-Module Outer Margin
The 'quiet zone' is the white buffer around the matrix. Overlapping it with text, shadows, or borders breaks the camera's ability to decode data points.
Do: Leave at least 4 module widths of clean whitespace all around the code.
Don't: Don't overlay stickers or graphics that intrude into the code perimeter.
Testing05
Physical Paper Test Scan Before Batch Printing
Screen scanning is much more forgiving than ink on paper. Print a single sheet and test it under varied lighting and angles using multiple smartphones.
Do: Test with at least one iPhone and one entry-level Android phone before mass printing.
Don't: Don't send packaging runs to print without a verified physical prototype scan.
Durability06
Protect Outdoor Physical Codes from Glare & Scuffs
For outdoor menus, table stands, or window displays, laminate with a matte finish to prevent harsh sunlight reflections from blinding the phone camera.
Do: Choose matte lamination or UV-protected coatings for outdoor signage.
Don't: Don't use highly reflective glossy acrylic covers in direct sunlight.
Pro-Tip for Maximum Conversions
Always test your WhatsApp assets (links, messages, images, and QR codes) on both mobile and desktop before launching marketing campaigns or printing physical collateral.
