The first dimension stated when describing a poly bag is the width. All bag measurements are inside diameter (ID)
Width = (the circumference of the drum divided by 2) + 2”. It is easiest to use a flexible tape measure and measure around the widest part of the drum.
Length = (height of the drum + the width [diameter]) + 4”. The extra 4” provides the extra material to fold over or tie the bag.

Width = (the circumference of the box divided by 2) + 2”. The circumference equals the sum of the length of each side.
Length = ½ the narrow width + the height of the box. Add 5” for results less than 96” and add 8 “ for results greater than 96” for fold over or tie off.

Hopefully they can go here.....
