To calculate the girth of your parcel please follow these guidelines:
1. Measure the parcel dimensions for centimeters, this is the length x width x height. Example: 20 cm length x 40 x width x 20 cm height.
2. With the two smallest dimensions add them together and multiply the result by 2, this will be the girth of your parcel. Example: 20 cm length + 20 cm height= 40 cm x 2=80 cm girth.
3. Lastly, take the largest dimension and add this to the girth and this will be the length and girth combined of your parcel. 40 cm width + 80 cm girth = 120 cm (combined length and girth)
