Length and girth formula
The longest side is treated as the package length. Girth is twice the sum of the other two sides. The checker adds those values and compares both measurements with the maximum limits you enter.
Use your carrier’s exact limits
Carriers can define measurements differently and may also set weight, shape, service or surcharge rules. This checker does not contain carrier limits and cannot confirm that a parcel will be accepted. Verify the latest requirements with your carrier before buying a label.
