Plastic Bag Size Guide

Width - The width (W) of the bag specifically refers to how long the X axis of the bag is. Measure this from left to right, and note it down.

Length - The length of the bag specifically refers to how long the Y axis of the bag is. This is often also referred to as height (H). Measure from bottom to top, and note this down.

Gusset - Lots of plastic bags do not have a gusset, therefore if the bag does not have one, it does not need to be included in the measurement. The gusset (G) of the bag specifically refers to how long the Z axis of the bag is when folded out. Ensure the bag is fully folded out and not slack, then measure from left to right and note this down.

When selecting your bag size, you must list your sizes in the correct order. This should follow the XYZ axis order, or Width, Height, Bag Gusset.

In this example, the size should be presented in the following way:

Width x Length x Bottom Gusset
