Design a QR code that people can actually scan
A clear code and a reliable destination matter more than elaborate decoration.
Protect the empty margin
A standard QR code needs a clear margin at least four modules wide on every side. A module is one small square in the pattern. Keep borders, text, and decoration outside that area; the margin is part of the code's usable design, not spare space.
Prefer contrast to ornament
Use clearly separated dark and light areas. A wood-inspired or engraved treatment should still have distinct modules and an even background. Do not place a logo over the pattern or assume error correction will rescue every design. Reflections, printing, and surface texture can change the result.
Test the final size
Scan a physical proof if you can. Try a few phones, ordinary indoor light, and a slightly angled handover. A huge code on your monitor is not a useful test of a small printed code. On iPhone, use Camera in Photo mode and tap the detected link.
Check where it goes
Read the destination before opening it, then confirm that the profile is public and current. If scanning succeeds but the page fails, investigate the address and connection rather than redrawing the code.
- Keep the quiet zone empty.
- Test after printing, not only before.
- Use a short, stable destination you control.
- Check the final page while signed out.
