Multiply the Girth times the Length for the overall package dimension.
The last set of windshield rubber trim that was (accidently) shipped to me came in a heavy cardboard tube cylinder.
Your Package Size
To measure ground packages use the following formula:
Length + 2x Width + 2x Height
Step 1. Determining Length
Measure the longest side of the package, rounding to the nearest inch. This is your length.
Step 2. Determining Girth (2x Width + 2x Height)
Measure the width of the package, rounding to the nearest inch. Multiply this number by 2.
Measure the height of the package, rounding to the nearest inch. Multiply this number by 2.
Add these two numbers together. This is your girth.
Step 3. Add the length and the girth together. This is your package measurement.
Step 4. Weigh the package to obtain its actual weight.
Ok, lets say length is 60", width is 10" and height is 10", according to the formula above the totals would be 60" + 20" + 20" which would be a total of 100" which is well within the parameters for size allowed for regular shipping, weight with packaging can't be more than 5 lbs so why would special, expensive shipping charges apply?
