To determine proper bag size for use with round containers:
Circumference = Diameter x 3.14
- For the circumference of the bag, multiply the diameter of the container by 3.14. Divide by 2 to get the flat width. Add 1 inch for a looser fit.
- Add 1/2 of the diameter to the height of the container. Add 4 inches to this value for overhang. This is the total length of the bag needed.
- If tying bag, add 1/2 of the diameter to bag length in Step 2.
