To determine proper bag size for use with a square or rectangular container:
When determining the flat width of the bag needed:
- Add the width and length of the sides.
- Add 1 inch for a looser fit.
To determine the length needed:
- Add 1/2 of the shortest side to the height of the container.
- Add another 4 inches to this value for overhang.
- If tying bag rather than lining a box, add 1/2 length of the shortest side to the bag length in Step 2.
