Micro QR generator

The smallest variant of the QR code, with a single position marker. It holds up to 35 digits and marks very small items.

Code settings

Up to 35 digits, 21 capital letters and digits, or 15 bytes of text.

The side of one square (module) of the code. Recommended 0.25 to 2 mm.

Blank margin around the code required by the standard. Keep it on.

A higher level reduces capacity. For longer content only level L may work.

Appearance

Hexadecimal, for example #000000.

Fills the quiet zone too.

What is Micro QR

Micro QR has only one square marker in the corner instead of three, so it is much smaller than a regular QR. It holds very little data, though: at most 35 digits.

It needs a quiet zone 2 modules wide, half that of a regular QR. A higher error correction level reduces the capacity.

Frequently asked questions

Can a phone read Micro QR?

Not every phone can. Many apps and built-in cameras read only regular QR codes. Micro QR is used with industrial readers.

How much data fits in Micro QR?

At level L at most 35 digits, 21 capital letters and digits, or 15 bytes of any text. Less at higher levels.

When should I choose Micro QR over Data Matrix?

When a customer or reading system requires it. Otherwise Data Matrix holds more data on a similar area.

Why does the preview show an error at a higher level?

A higher error correction level reduces capacity and the content no longer fits. Shorten the content or choose level L.

Which module size should I choose?

It depends on the reader and printing. The generator defaults to 0.5 mm, but smaller modules are also used for marking parts.
