Are you planning a gathering and wondering, "18 inch pizza feeds how many?" You're not alone! Many people struggle with ordering the right amount of food, especially when it comes to pizza. An 18-inch pizza is one of the largest standard sizes available, making it a great choice for sharing. But how many people can it actually serve?



An 18-inch pizza has a diameter of 18 inches, giving it a surface area of approximately 254 square inches. Most pizzerias cut this size into 8 to 12 slices, depending on their serving style. If each person eats about two to three slices, this pizza can comfortably feed 4 to 6 people. However, factors like appetite, side dishes, and event type can influence portion sizes.



For small gatherings, one pizza might be enough, but for larger groups, ordering multiple pizzas ensures everyone gets their share. If you’re serving kids, you might get away with fewer slices per person, while a group of hungry adults might require more. To be safe, always consider ordering extra, especially if leftovers are welcome!
