The History of Plate Sizes
Fast foods do not have a monopoly on supersize. The plate industry has had its own growth spurt during the past 50 years. In the 1960s dinner plates were about 8.5 to 9-inches in diameter and held about 800 calories; by 2009 plate size had grown to 12-inches with the capacity to hold about 1900 calories. The calorie differences are illustrated in the graphic below. (Calorie amounts will vary depending on the foods you choose.)
