# Common QR Code Mistakes and How to Avoid Them
Creating a QR code takes only a few minutes, but a small mistake can make it useless. A broken website link, poor print quality, or bad color choice can stop people from reaching your content.
The good news is that most QR code problems are easy to prevent. A few simple checks before printing or sharing your QR code can save time, money, and frustration.
This guide explains the mistakes people make most often and shows you how to avoid them.
## Using the wrong website link
The most common mistake is adding the wrong URL.
Sometimes people copy the wrong page or forget part of the website address. When someone scans the QR code, they see an error page instead of the information they expected.
Always test the link before creating your QR code.
After generating the code, scan it with at least two different phones to confirm it opens the correct page.
## Printing the QR code too small
A QR code needs enough space for a phone camera to read it.
If the code is too small, many devices will struggle to scan it, especially from a distance.
For printed materials, choose a size that is easy to scan without forcing users to move their phone very close.
## Poor color choices
Black on a white background remains the easiest combination for cameras to read.
Very light colors, low contrast, or busy backgrounds can reduce scanning accuracy.
If you want to match your brand colors, test the QR code carefully before using it on posters, flyers, or product packaging.
## Forgetting to test the QR code
Many people generate a QR code and print hundreds of copies without testing it.
That's a costly mistake.
Scan the code with Android phones, iPhones, and different QR scanner apps.
Testing takes only a minute and helps you find problems before your customers do.
## Stretching or editing the QR code
A QR code should keep its original shape.
Stretching the image, squeezing it, or adding heavy design effects can make scanning difficult.
If you need a larger version, download a high-quality PNG or SVG file instead of resizing a small image.
## Covering the code with a logo
Adding a logo can make a QR code look more professional.
The logo should stay small.
If it covers too much of the pattern, some phones won't be able to read the code correctly.
Always scan the finished design before publishing it.
## Printing on reflective surfaces
Glossy materials sometimes reflect light into the camera.
That reflection makes scanning harder.
Whenever possible, print QR codes on surfaces that reduce glare and remain easy to read under different lighting conditions.
