Massive pizzas are oversized versions of the traditional pizza, often measuring 18 inches or more in diameter. They can be found in various styles, including Neapolitan, New York, and Chicago deep-dish. These pizzas typically feature a thicker crust and a larger amount of toppings, making them ideal for sharing among groups. Many pizzerias offer massive pizzas as a specialty item, sometimes even challenging customers to finish them in a set time. Some establishments host competitions where participants attempt to eat a giant pizza, often weighing several pounds. These events can attract pizza enthusiasts and create a fun, communal atmosphere.
