A QR code doesn't have to be a plain black-and-white square to work well — but design choices should always prioritize function over form. This guide covers how to make a QR code that looks good and still scans reliably every time.

Color Choices

You can customize both the foreground (dark modules) and background color of your QR code, but contrast is critical. As a general guideline:

  • Keep the foreground significantly darker than the background.
  • Avoid similar hues (e.g., dark blue on black, or light yellow on white).
  • When in doubt, classic black-on-white remains the most reliable and universally scannable option.

Adding a Logo

Placing a small logo in the center of a QR code is a popular branding technique. To keep the code scannable:

  • Keep the logo under roughly 20-25% of the total QR code area.
  • Use a High (H) error correction level, which allows up to 30% of the code to be obscured while remaining scannable.
  • Add a small white border or padding around the logo to maintain clear separation from the surrounding pattern.

Shape and Style Variations

Some QR generators offer rounded corners, dot-style modules, or custom eye shapes (the three large squares in the corners). These stylistic choices can look more polished, but always test thoroughly, since more decorative styles are generally slightly less reliable than the standard square-module design, especially at small sizes.

File Format: PNG vs SVG

PNG

A raster image format, ideal for digital use like websites, social media, and email. PNG files have a fixed resolution, so enlarging them significantly can cause blurriness.

SVG

A vector format that scales to any size without losing quality, making it the best choice for professional printing, especially for large-format materials like posters or banners.

Sizing Guidelines by Use Case

  • Business cards: 0.8–1 inch
  • Flyers and posters: 2–4 inches
  • Storefront windows: 6–12 inches
  • Billboards: several feet, scaled to the expected viewing distance

Placement Within Your Design

Avoid placing a QR code near the edge of a printed material where it might get cut off during trimming. Leave adequate white space (the "quiet zone") around the code, and avoid overlapping it with other design elements or text.

Testing Before Finalizing

Always print a physical test copy at the actual intended size and material before committing to a full production run. Screen previews don't always reflect how a code will scan once printed, especially on textured or colored paper stock.

Final Thoughts

Good QR code design balances visual appeal with reliable functionality. When you customize colors, add a logo, or choose a file format, always keep scan reliability as the top priority. Design yours with our free QR Code Generator, complete with color customization and logo upload.
