Make a QR code that is easy to scan
Choose useful content, clear colors and a proper border, then test the exact version you plan to share.
Start with the right content
Choose the content type before adjusting the design: a link, text, Wi-Fi details or contact information. Check every character, because the code carries the information you enter. For a website, use the intended complete address. Avoid removing parts just to shorten it if they are needed to open the correct page.
More data can require a denser pattern. Include what the recipient needs, especially when the code will occupy a small space on a card or label.
Keep the border clear
A regular QR code needs an empty border at least four small modules wide on every side. This quiet zone supports recognition; it is not spare space to crop away. Preserve it when placing the code inside another design, and keep nearby headings, frames and decoration outside it.
Leave the large corner patterns visible and keep the code proportional when resizing it.
Customize gradually
Begin with dark elements on a clear, light background. Similar colors and busy backgrounds can make the pattern harder to distinguish. Keep an added logo small and away from the corner patterns, and compare the result with a version without the logo.
Higher error correction can help with some damage, but it does not guarantee that a large logo covering important parts will remain readable.
Test the final version
Download the file and decode it to check its contents. Then scan it with a phone in its intended setting. For print, try the actual finished size before distributing copies. Repeat after changing the color, logo or size; a successful preview scan does not establish that the printed version will work.
