We have been working on the cheese issue for several years now, not so much for an industry standard, for which there isn’t, but instead to find out what the minimum acceptable cheese amount is for a 12-inch pizza. We have found that 3.75-ounces is about the minimum, so 3.75 divided by 113 = 0.033-ounces for each square inch. the most common amount that I’ve encountered over the years is 6.5-ounces of cheese for a loading factor of 0.06 (actual: 0.0597345). With all of this said, What I encourage operators to do is to find a cheese amount that works best for them based on the type of pizzas, type of cheese used, and above all else, customer preference/acceptance. then divide the weight of cheese used be the surface area of the pizza you used it on. The cheese loading factor can then be used to calculate the amount of cheese that you should use for larger or smaller pizzas of the same type. We use loading factors all the time for calculating dough, sauce, and cheese weight for the different size pizzas.
