Testing a QR Code Before You Print It: A Checklist

A short checklist for testing a QR code on screen and on paper so you catch problems before printing hundreds of copies.

A wrong QR code on a thousand flyers is an expensive mistake. Testing takes a few minutes.

Step 1: check the content

  • Scan the code and read the result carefully.
  • Open the link and make sure the page loads.
  • Check spelling and any numbers, such as phone numbers.
  • Check the page on a phone, since many pages look different on mobile.

Step 2: test on more than one phone

Scan with at least two different phones, and if possible include an older one. Different cameras behave differently.

Step 3: test a printed sample

Screens are backlit and sharp. Paper is not. Print one copy at the real size and scan it.

  • In bright light
  • In dim light
  • From the real distance people will use
  • At a slight angle

Step 4: test the surface

If the code will go on a curved bottle, a glossy sign or a window, test it on that surface, not on flat paper.

Step 5: check the surroundings

  • Is the quiet zone clear?
  • Is there a short line of text saying what the code does?
  • Is the code at a comfortable height?

Step 6: check the destination later

If the code points to a web page, that page needs to keep working. Set a reminder to check the link now and then.

A quick checklist

  1. Content correct
  2. Two or more phones tested
  3. Printed sample scanned
  4. Surface tested
  5. Border and label in place

QR Code Scanner keeps a scan history, which makes it easy to compare what each test scan returned.
