Print QR Code Size Guide

Step-by-step instructions

1. Decide how far away people will scan the QR code.
2. Pick a size that matches the scanning distance.
3. Use SVG for print to keep edges sharp.
4. Keep strong contrast and a clear margin around the code.
5. Print a test copy and scan with two devices.

The simple size rule: 1 to 10

A good rule of thumb is that the scan distance should be about 10 times the width of the QR code. If your QR code is 2 cm wide, people can scan it from about 20 cm away. If it is 10 cm wide, it can be scanned from about 1 meter away. This is not exact, but it is a reliable starting point.

Distance rule QR size 2 cm  -> scan from ~20 cm QR size 5 cm  -> scan from ~50 cm QR size 10 cm -> scan from ~1 m

If you expect people to scan while walking, choose a larger size to reduce missed scans.

Practical sizes for common materials

• Business cards: 2 to 2.5 cm (about 0.8 to 1 inch).
• Flyers and menus: 3 to 4 cm (about 1.2 to 1.6 inches).
• Posters and windows: 6 to 10 cm (about 2.5 to 4 inches).
• Banners or outdoor signs: 12 cm or larger for distance scanning.

These are safe defaults. If your QR code contains a long URL or high error correction, consider going a bit larger.

Use SVG and keep strong contrast

For printing, SVG is the best format because it stays sharp at any size. PNG works for digital use, but printing can make it blurry, especially if you scale it up. Always keep high contrast between the QR code and the background. Black on white is the safest choice.

Avoid placing QR codes on busy images. If you must, add a solid white box behind the code to improve scanning.

Avoid auto scaling when printing

Many printers and PDF viewers shrink content by default. Choose "Actual size" or "100%" so the QR code prints at the intended size. If you use "Fit to page", the code can become too small and harder to scan.

If you send files to a print shop, include the exact size in mm or inches and ask them to keep it unchanged. A small change can affect the scan distance you planned for.

• Export at 300 dpi for sharp edges.
• Leave margins so the QR code is not near the page edge.
• Test on the final paper stock if possible.

Leave a quiet zone around the code

Scanners need a clean margin around the QR code to detect its edges. This is called the quiet zone. Leave at least 4 modules of white space around the code. In practice, this means a small margin of white space on all sides, even if the background is already light.

If a QR code is placed too close to other graphics or text, scanning becomes unreliable. Keep the area simple and clear.

Plan for lighting and surfaces

Lighting changes how a QR code scans. Glossy paper, plastic covers, or window decals can reflect light and make scanning harder. If you can, use a matte finish or place the code where light does not bounce directly into the camera.

Dark codes on light backgrounds are still the most reliable. Avoid light gray codes or busy patterns. If you need color, keep the QR modules dark and the background bright.

• Use matte paper for menus and table tents.
• Keep the background solid and uncluttered.
• Avoid placing QR codes across folds or seams.

Test print before final production

Always print one test sheet and scan it with at least two phones. Test from the expected distance and lighting. If scans are slow, increase the size or simplify the content. This short step prevents expensive reprints and saves time.

If you are printing many QR codes, the Print Sheet tool can lay them out on A4 with labels so they are ready to cut or paste.
