About this calculator
The plate method, popularized by the American Diabetes Association and USDA's MyPlate guidance, is a visual portion-control approach for a standard round plate: roughly half non-starchy vegetables, a quarter lean protein, and a quarter starchy carbohydrates, all judged by area rather than by weighing or counting anything.
This calculator divides a plate's area by those proportions to show the actual size each section should take up on your specific plate diameter. It's used by people managing diabetes or working on weight goals, dietitians teaching portion control, and anyone who wants a simple, no-math visual for meal planning.
