How to print QR code stickers that scan
Keep the code itself at about an inch square or larger, leave a clear margin of at least four modules around it, print dark on light, and choose matte so overhead light does not reflect into the camera.
| Scanned from | Code width printed guidance suggests | Sticker size that leaves room for it |
|---|---|---|
| In the hand, arm length | About 1" | 2" with a line of text, 1.5" bare |
| A table or counter, 2 to 3 feet | About 2.5" to 3.5" | 4" |
| A doorway or window, 6 feet | About 7" | 8" or larger |
| Across a room, 10 feet | About 12" | 12" or larger, or a cling on the glass |

The ten-to-one rule, and where the numbers come from
The working rule printed guidance generally agrees on is that a QR code is read from roughly ten times its own width. A one-inch code is comfortable at about ten inches - a phone held normally. A code that has to be scanned from six feet away needs to be about seven inches wide, which is a size most people are surprised by.
The figures in the table above are that rule applied, with a little headroom. Add more if the code will be read in poor light, at an angle, or by someone in a hurry - all three make a camera work harder, and all three are normal conditions for a code on a door or a vehicle.
The quiet zone is the thing most designs get wrong
A QR code needs an empty margin around it, conventionally described as four modules - four of the small squares the code is made of. A scanner uses that margin to find where the code begins. Printing a border, a logo or a line of text inside it is the single most common reason a code that looked fine on screen fails on paper.
The practical version: whatever is in your file around the code, leave a clear band of background at least as wide as four of its little squares. On a 1" code that is roughly an eighth of an inch of nothing.
Contrast, finish and the materials to avoid
Dark code on a light background, always - inverted codes and codes over photographs or gradients are where scanning becomes a coin toss. Glossy laminate is the other trap: it reflects ceiling lights and sunlight straight back into the camera, and a single bright highlight across the middle of a code stops it reading. Matte scatters that light, which is why our QR sticker page opens on matte.
Two of our materials need care with a code. Clear vinyl lets whatever is underneath show through the modules unless there is white behind them - our free dynamic codes get white ink on clear, and a code in your own file should sit on a white panel. Holographic film shifts color across the modules, so keep the code on a solid light patch inside the design.
Outdoors, on glass, and testing before you print a thousand
Laminated vinyl is waterproof and holds its print outdoors for years, so a code on a shop door, a job sign or a vehicle is an ordinary sticker job. A code that goes on the inside of a window and is scanned from the street is a cling, printed mirrored so it reads the right way round through the glass.
Whatever the material, scan the proof. We send a free online proof before anything is printed, and it lets you check the code itself: open it on screen, scan it with a phone, and you have confirmed that the code works, where it leads and that its margin is intact. What a screen cannot show is the print in place - a small code, glare on a glossy surface or a long scanning distance - so scan the first printed sticker where it will be used before you put up the rest.

Questions people ask
- What is the minimum size for a printed QR code?
- About one inch square for a code scanned with a phone held at arm length. Printed guidance varies a little either side of that; an inch is the conservative version, and it is what we would order.
- Do you generate the QR code?
- Yes, free, when you order from one of our QR code pages, such as QR code stickers: tick Add a free dynamic QR code, paste your link, and the code is on your proof; you can change where it leads later in My QR codes in your account, with no subscription. If you bring your own code, we print it exactly as supplied.
- Matte or glossy for a QR code sticker?
- Matte. Gloss reflects overhead light into the camera, and a highlight across the code is enough to stop it reading. Matte costs the same.
- Can a QR code go on clear or holographic vinyl?
- On clear, yes, with white behind the whole code - we add it to our dynamic codes, and in your own file put the code on a white panel. On holographic, keep the code on a solid light patch and scan the proof before you approve.
- How big should a code on a window or a vehicle be?
- Work back from the distance people will stand at, using ten times the code width as the guide. Six feet means roughly a seven-inch code, which usually means an eight-inch sticker or a cling.
- Can I put a logo in the middle of the code?
- Many QR tools allow it and add error correction to cover it; our free dynamic codes stay plain black on white, which scans most reliably. A code with a logo goes in your own file - we print it as supplied, and the proof lets you scan it before it goes to press.
