Bag or Liner Size Formula

                    

Width of the liner = (the circumference of the drum divided by 2) + 2″
                                      =(length plus width of a box) + 2
***for gussetted liners you can add 1″ each to the lenght and width of the box to get the gusset dimensions
 
Length the liner = (height of the drum + the width(diameter)) + 4″
                                  = (depth of the box + 4-7″)

If you don’t have a flexible tape to measure around the drum/box or given the information in an email, how do you calculate the circumference?

Circumference = Pi (3.14) times Diameter (C=pD)
