What Size Should a QR Code Be for Printing? (Size Chart)
QR print size depends on how far away someone will scan, how much data the code contains, and the quality of the final print. Use the examples below as test sizes, not guaranteed minimums.
A code on a card is scanned close up; a sign may need to be read from across a room. A handy first estimate is to make the code's width about one tenth of the intended scanning distance. That is a rule of thumb for planning a test—not a certification that every phone, print process, or QR design will work at that size.
Starting sizes to test
| Intended scan distance | Try this width first | Example use |
|---|---|---|
| 8 in (20 cm) | 0.8 in (2 cm) | Business card or small product label |
| 12 in (30 cm) | 1.2 in (3 cm) | Table tent or counter sign |
| 2 ft (60 cm) | 2.4 in (6 cm) | Hand-held flyer |
| 3 ft (0.9 m) | 3.6 in (9 cm) | Wall poster in a small room |
| 6 ft (1.8 m) | 7.2 in (18 cm) | Entrance or shop-window sign |
| 10 ft (3 m) | 12 in (30 cm) | Large sign viewed from a few steps away |
Measure the distance from the scan position to the printed code, not to the edge of the sign. Increase the code size if it contains a long URL or contact card, uses a logo, will be printed on a curved surface, or must be scanned in poor lighting. For roadside or moving-viewer uses, get a print proof and test it from a safe, realistic viewing position rather than relying on this table.
Account for the quiet zone
Leave a clear, light margin around all four sides of the code. A standard QR code uses a quiet zone at least four small modules wide; keep text, borders, and nearby artwork outside that area. Remember that this margin takes up space too: reserve more room on the printed layout than the pattern alone appears to need.
Things that make a code need to be bigger
- Dense data. A long URL or vCard can produce a denser pattern. Consider shortening the URL or linking to an online contact page, then check the actual exported code.
- A logo or custom styling. Decoration can cover or reduce the contrast of modules. Keep it modest and test the final version; error correction is not a guarantee that a covered code will scan.
- Material and lighting. Curved packaging, glare, smudges, and dim light can make alignment harder. Test on the surface and under the lighting where the code will be used.
Contrast and colors
Use a simple, high-contrast design—typically a dark pattern on a light background. Avoid placing the code over a photograph or using colors that look distinct on your monitor but merge when printed. Check a physical proof under the lighting in which it will be scanned.
Which file format to send to the printer
| Format | Best for |
|---|---|
| SVG | When the print workflow accepts vector files; it can scale without pixelation, but still needs a proof check. |
| PNG | When a raster image is needed. Choose enough pixels for the final print size and the printer's resolution. |
| JPG | Only when required by the workflow; compression artifacts can soften sharp code edges. |
For a raster file, calculate the needed image dimensions from the print width and the print workflow's resolution. For example, a 3-inch image at 300 pixels per inch needs 900 pixels across. The download's pixel count alone does not determine the physical print size.
Use a proof before a large print run
Print one sample at its intended dimensions. Scan it from the planned distance with more than one device if possible, then confirm that it opens the correct destination. If it fails, simplify the design or increase the size and run the test again before ordering the full batch.
