Cereal box size depends on the cereal brand and the volume size. For example, a box that is 12 inches long, 7 5/8 inches wide and 2 1/2 inches deep is required to hold 12.8 ounces of Multi Grain Cheerios.
The ready-to-eat cereal market is a $13 billion industry, and some cereal companies use bio-plastic bags in place of cereal boxes. Generally, cereal boxes are made of chipboard, or paperboard. This is a different type of paper grade than regular cardboard. It is not possible to recycle cereal boxes. Consumers can create individualized cereal boxes online using their own pictures.
