Barcode Dimensions

 

Barcode Dimensions (EAN-13 product)

When we send you your barcode images, we email them in standard size which is approximately 38mm wide by 25mm tall. You can resize the images if necessary to fit your product packaging or label, however please pay attention to the allowable barcode dimensions below (especially if some of your retailers require barcode verification). The smallest recommended barcode size for an EAN-13 barcode is 80% of standard size (approx. 30mm wide x 20mm high). 

At 100% magnification:

 

Barcode Magnification Requirements:

An EAN-13 barcode can have a magnification range of 80% – 200% (X-dimension 0.26mm-0.66mm), if scanned at retail*

“Width” = the width of the vertical black barcode bars only (the size of the Left & Right Quiet Zones must be included to find the total required barcode width).

“Bar Height” = the height of the barcode bars only. The barcode number must also be included below the barcode bars (however the size & font of this is up to you – as long as it is readable).

“Quiet Zone” = the empty white space, or margin, on either side of the barcode. These are mandatory (a barcode with quiet zones that are too small will fail its verification report). Many barcode images have a > on the right hand side after the numbers – this is optional, but is used to give a visual indication of the right side quiet zone that is needed.

NOTE: A minimum magnification of 75% (X-dimension 0.25mm) is allowable only with certain on demand print processes (eg. thermal), however this applies only to the width of the barcode (the height of the barcode must remain at the 80% magnification size or larger).

* If an item is being scanned in a General Distribution situation (automatic scanning), the magnification range is 150% to 200% (X-dimension 0.50mm – 0.66mm).

Barcode Dimensions (ITF-14 carton)

Below are the ITF-14 Barcode Specifications in millimetres.

Magnification:

The specified magnification range for an ITF-14 Barcode Symbol being scanned in a General Distribution Scanning environment is between 50 and 100%. For other scanning environments the range is 25-100%

If printing onto corrugate fibreboard the ITF-14 should be above 62.5%.

Height of Bars:

The minimum height for the bars in a General Distribution Scanning Environment is 32mm.

In other scanning environments the bar height should be as high as possible. 13mm is the minimum bar height, hence all ITF-14’s should exceed this height however every effort should be made to ensure that the height is as close as possible to 32mm.

Bar Width Ratio:

The bar width ratio is 2.5:1. The acceptable range for this ratio is between 2.25:1 and 3:1.

Human Readable Interpretation:

Font, font size and location are not specified however these should be printed clearly in proportion to the rest of the barcode. It is preferred for the font to appear below the barcode.
