The guide will give you answers on how to ensure the correct size of your barcodes.

How big should the EAN-13 and EAN-8 be?

The guidelines for the sizes of EAN barcodes help to ensure optimal scanning at the exit boxes. Barcode dimensions are based on a normal size, denoted by a size factor of 1.0 (100%). The following table indicates symbol dimensions for the EAN-13 and EAN-8.

NOTE: Length indications include light zone. The height indications are the short strokes above the digits, and not the long ones on the sides.

‍

Light Zone

There should be a free area to the left and to the right of the barcode symbol - this area is called the light zone.

Light zone size for EAN-13 barcodes:

Left light zone = 11 x the module width (X in the diagram below)
Right light zone = 7 x the module width (X in the diagram below)

The size of the light zone for EAN-8 barcodes: ‍

Left light zone = 7 x the module width (X in the diagram below)
Right light zone = 7 x the module width (X in the diagram below)

Altitude reduction

As far as possible, you should avoid height-reducing the barcode. Height reduction of barcodes should be made only if absolutely required. When the height of the barcode symbol is reduced, scanning the barcode can become more cumbersome.
