Free interactive print planner
Will your QR code actually scan when printed?
Get a practical print-size recommendation from the viewing distance, QR code density, and print DPI. Includes the often-forgotten blank margin around the code.
01 / Define your print
Where will people scan?
Choose a print scenario and expected camera distance.
Code density depends on actual encoded data and error correction. These options are illustrative QR versions, not an automatic analysis of your QR artwork.
02 / Your print specification
Recommended overall width (including quiet zone)
7.5 cmA conservative planning recommendation with a 25% buffer above common distance and printing heuristics. Not a scan guarantee.

Always print a physical proof
Maintain high contrast and a completely clear quiet zone. Test with multiple phones, in real lighting, at the expected scan distance before ordering a large print run.
How the calculator works
Three constraints determine the print.
01 · Distance
A common starting guideline is a symbol roughly one-tenth the scan distance. We add a 25% design buffer rather than treating the rule as a guarantee.
02 · QR version
Version 1 has 21 modules per side. Each step adds four. Dense content increases the number of tiny squares the printer and camera must resolve.
03 · Quiet zone & DPI
Four clear modules are required on all sides. We also plan for at least four printer dots per module and a conservative 2.5 cm total-size floor.
An example: a QR code for a menu stand
At 60 cm scanning distance, our planning rule starts with approximately 6 cm of overall width before the 25% buffer. With standard density and 300 DPI, the recommended printed QR artwork measures 7.5 cm across, including the quiet zone. If the actual code encodes a very long link, increase the size or shorten its encoded destination.
QR print sizing questions
How big should a QR code be on a business card?
Start with about 2.5 cm (roughly 1 inch) including the clear quiet zone when scanning at arm’s length, then test the actual printed card. Longer URLs or complex designs may require more space.
What is the quiet zone around a QR code?
The QR code specification requires four blank modules on each side. The calculator includes that margin within its recommended total width and reports the width of one quiet-zone side.
What changes when a QR code contains more data?
A longer encoded value can require a higher QR version with more modules per side. At the same printed size, those individual modules become smaller and more difficult to reproduce or scan.
Does higher DPI mean a QR code can always be printed smaller?
No. Higher print resolution improves the ability to reproduce fine modules but does not overcome limitations from camera distance, lighting, substrate, contrast or focus.
Can I trust this calculator instead of testing?
No. It is a conservative design starting point, not a promise of readability. Print a proof, keep the blank margin, and test multiple phones at the actual expected distance.
Calculation basis and limitations
Module counts and the four-module quiet zone follow the QR Code documentation published by DENSO WAVE. The 10:1 distance heuristic, 25% design buffer, 2.5 cm planning floor and four-dots-per-module print floor are practical design assumptions, not manufacturer warranties or universal minimums. Real scanning depends on the content, scanner, material, printing and lighting.
