== Barcode weight ==
 +
For EAN-13 barcodes, GS1 recommend barcodes' weight to be ~32mm. In general, producers tend to use barcodes between 24 and 35 mm. Values below 24mm and above 35 are rare.

 +
It's interesting to control that our apps are playing well with different barcodes' size. We build a [https://docs.google.com/document/d/12VtFOsnHfK4PVwBJy_aHwSogX_yKRNfzoiHCPD1sxN0/edit# test document] that you can print and use with the app.
