ITF-14 Barcode Dimensions
Below are the official ITF-14 Barcode Specifications in millimetres. These standards define the allowed sizes for your barcodes on shipping cartons.
Bearer Bar Requirements
The top and bottom bearer bars are mandatory. Vertical bearer bars are optional only if using a printing method that does not require printing plates.
Magnification
General Distribution: 50% to 100%.
Other Environments: 25% to 100%.
*Use >62.5% if printing on corrugated fibreboard.
Bar Height
General Distribution: Min 32mm.
Others: Min 13mm. Every effort should be made to stay as close to 32mm as possible.
Bar Width Ratio
The standard ratio is 2.5:1. The acceptable range for this ratio is between 2.25:1 and 3:1.

It is best to allow more space for the quiet zones than the minimum in case of ink spread.
Standard Definitions
- General Distribution Scanning: Automated scanning by machine as items pass on a conveyor belt.
- Other Scanning Environments: Typically refers to manual handheld scanners.
- Quiet Zones: Essential white space on either side of the bars.
