The Girth Formula for a box is this: 2x (width + height)..... for example if a box's length measures 30" along each side, the width being the measurement of the smaller adjacent side is 30" as well, and the distance from top to bottom of the box would be the height.... let's say it's 12". So the Girth would equal= 2x (30+12)=84"

so basically a 30"+ 30"X 12" box has a girth of 84"

Hope that helps!
