Question 1

What is a QR code?

Accepted Answer

A QR (Quick Response) code is a two-dimensional barcode that can store information like URLs, text, phone numbers, emails, and WiFi credentials. When scanned with a smartphone camera, it instantly opens the encoded content — making it perfect for print materials like flyers, posters, and business cards.

Question 2

What is the best QR code size for printing?

Accepted Answer

For most printed materials, a QR code of at least 2 cm x 2 cm (about 0.8 inches) works well for close-range scanning. For posters and banners meant to be scanned from a distance, use a larger size — at least 256 px or 512 px when generating. As a rule of thumb, the scanning distance is roughly 10 times the QR code width.

Question 3

What resolution should I use for a printed QR code?

Accepted Answer

For crisp, scannable results in print, generate your QR code at 512 x 512 pixels or higher. This ensures the code remains sharp even when printed at larger sizes. Avoid using 128 px codes on posters — they may appear blurry and fail to scan reliably.

Question 4

Can I customize the colors of my QR code?

Accepted Answer

Yes! Our generator lets you pick custom foreground and background colors. However, for reliable scanning, always maintain high contrast between the foreground and background. Dark foreground on a light background works best. Avoid light-on-light or dark-on-dark combinations as scanners may not read them.
