# Formula for Calculating Warp Measurement of Corrugated Boxes

D

#### DCCockrum

I am researching the formula for calculating warp in corrugated boxes. I am trying to demonstrate that the measurement is not lineal. So far all I have found is the formula for arc radius calculations of r= (W^2) / (8H) + (H/2). Where W is length, H is bulge. Does anyone have anything better?

Maybe this document will help.
