QR codes for retail and packaging

Packaging codes that survive small print areas, and codes you can repoint from a launch campaign to an evergreen page.

Start here

Packaging is small, so keep the URL short: Every character in the encoded URL adds modules, and more modules means each one is smaller at the same printed size. A short dynamic link fits where a long product URL will not.
Do not print on the curve if you can avoid it: Bottles and tubs distort the pattern. Where a curve is unavoidable, keep the code small relative to the curve and raise the error correction level.
Plan for the campaign ending: Packaging outlives campaigns. A dynamic code can move from the launch page to an evergreen product page instead of becoming a dead link on stock still on shelves.

Every generator page calculates the exact size from your code’s density. These are the placements that matter for retail and ecommerce.
