What size bag do I need to fit my container?

For a round container:

1. For the bag's circumference, multiply the bag's diameter by 3.14. Divide that number by 2 to get the flat width. Add 1" for a looser fit.
2. Add 1/2 of the diameter to the height of the container. Add 5" to this total for overhang. This is the total length of the bag needed.
3. If tying the bag, add ½ the diameter to the bag length in #2.

Example:

Your container is 12" diameter X 12" tall

12" diameter X 3.14 / 2 + 1 = 19.84" wide

6" + 18" + 5" (for overhang) = 30" tall

So you would need a 20" wide X 30" long bag

For a square or rectangular container:

1. Add the width and length of the sides. Add 2" for a looser fit. This total equals the flat width of the bag needed.
2. Add 1/2 of the shortest side to the height of the container. Add 5" to this value for overhang. This equals the length of the bag.
3. If tying a bag rather than lining a box, add ½ the length of the shortest side to the bag length in #2.

Example:

Your box is 14" L X 12" W X 12"H

14" L + 12" W + 2" = 28" wide

12" H + 6" (1/2 width) + 5" (for overhang) = 23"

So you would need a 28" W x 23" L bag
