Email QR code — 720px PNG

Worked example

Make a email QR as a 720 px PNG for print up to about A6: enter an address, plus an optional subject and body, then scan the download.

A shop that prints a "questions?" card on its delivery slip should know that scanning only opens a draft; the customer still taps send. Put the order reference in the subject so replies are traceable, but avoid accents you cannot test, since some mail apps decode percent-encoding differently.

The email code is about 29 × 29 modules at level H, so after the default 18 px margin 684 of the 720 px hold the pattern and one module is about 23.6 px. Printed at 300 dpi the email code is 61 mm wide (2.00 mm modules), fits an A6 card of 105 × 148 mm and reads from about 61 cm.

Common mistake with a 720 px email code: trusting the PNG's built-in border as the quiet zone. On the email code the default 18 px margin is only 0.8 modules, while scanners want about 4 (94 px). The slider stops at 48 px (2.0 modules), so leave a blank border of at least 8.0 mm around the printed email code in your layout, and keep contrast at 4.5:1 or better, since the tool refuses to export below that.

The email code has only 29 modules, so at 720 px the default level H (about 30% recovery) usually tolerates the centred logo at 22% width.

Check the 720 px email file before using it: scan the download with two different phones, and for a print do it from about 61 cm, ten times its 61 mm width. At 720 px the result should be this: the mail app opens a draft addressed to hello@example.com, with your subject and body if you set them, and sends nothing.

A 720 px email PNG prints 61 mm wide at 300 dpi, so judge it at that size before sending it to print.
