How to find proper bag size for a box liner:

box dimensions

Find the Length (L), Width (W), and Height (H) of the box.

Width of bag: Length (L) + Width (W) + 2”
Length of bag: Width (W) + Height (H) + 2”

For example, if box size is 16”(L) x 6”(W) x 20”(H), then
Width of bag: 16”(L) + 6”(W) + 2” = 24” Wide
Length of bag: 6”(W) + 20”(H) + 2” = 28” Long

Bag size needed is 24" x 28"
