                                According to the USDA, a standard serving of air-popped popcorn is approximately 3 cups, but the volume of a pre-made or store-bought small bag of popcorn can differ dramatically depending on the vendor and type. While a small bag at one venue might hold just a couple of cups, another might pack in as many as five or more cups.
