Print PDF and sizes

Under the download buttons choose a paper size (A4 or Letter) and the printed width (3 to 16 cm), then press PDF. The file places the code at exactly that size with crop marks and the short link printed underneath, so a printer can check it.

Guidelines:

  • Minimum printed size is about 2 × 2 cm for close scanning; use 5 cm or more for posters scanned from a distance.
  • Use SVG when a designer will place the code in their own artwork; it is sharp at any size.
  • Use PNG (up to 2048 px) for screens, slides and social posts.
  • Always test-scan the final print with two different phones.
