BAG WIDTH:
Use one half of the outer circumference of the container.
BAG LENGTH: Use the height of the
container, plus one half of the diameter of the container bottom,
plus 3 inches (for overhang). For square or rectangular containers,
use the diagonal of the container bottom, rather than the diameter.
To find circumference - multiply the
diameter by 3.1416; or, divide diameter by 0.3183.
To find diagonal of a square - multiply side by 1.4142.
