QR Code URL Shortener: Smaller URLs Mean Simpler QR Codes The relationship between URL length and QR code complexity is direct and consequential: every character you add to a URL forces the QR encoder to use a higher version (larger grid), which means smaller modules at any given physical print size, which means the code is harder to scan. This isn't a minor effect. A 20-character URL might produce a Version 2 QR code with 25×25 modules. A 150-character URL with UTM parameters produces a Version 8 code with 49×49 modules. At 3 cm × 3 cm print size, the first has modules about 1.2 mm wide; the second has modules about 0.6 mm wide. That difference is the difference between reliable and unreliable scanning in real-world conditions. This guide explains the relationship between URL length and…
