Is your QR code or barcode big enough to scan on your label? Pick the kind of code, type what goes in it and the space you have. The answer updates as you type. It uses the same size rules as the Peelstack Label Maker add-on for Google Sheets™, and it runs in your browser: nothing you type is sent anywhere.

How to read the answer
A code is made of small squares or thin bars. The smaller they print, the harder it is for a phone or scanner to find them. In our own printed tests a phone camera read QR codes down to a square size of 0.20 mm, and Code 128 bars were read back down to 0.19 mm. Below 0.25 mm we suggest a test scan first. EAN-13 and UPC-A follow the limits of the retail barcode standard. Those tests used one inkjet printer and plain paper, so treat the numbers as a guide and scan a printed label before you print many.
A barcode needs white space on both sides, and the checker counts that too. EAN-13 and UPC-A numbers for products sold in shops must be registered with GS1; this tool checks size only, not whether a number is yours to use. QR Code is a registered trademark of DENSO WAVE INCORPORATED.
Peelstack Label Maker is our add-on for Google Sheets™ that makes a code for every row and tells you in the preview which rows are too small. See how it works.
