Catering for a party can be quite challenging. Fortunately, we work out the required quantities to make our catering so much simpler! Whether you order or make your own, running out of pizza or having too many leftovers is bound to turn the most awesome evening into a disappointment overnight. Our handy guide below gives you a great guideline as to how much pizza you should have depending on the size of your crowd – whether you are feeding 10, 20, or even 40 people!
The average adult will eat three slices of a traditional crust pizza, while a child tends to eat two slices. Naturally, women tend to eat fewer slices, often limiting themselves to 1 or 2 slices, while hungry men might demolish 4 to 5 slices!
As most large pizzas come portioned out into eight to ten slices per pie, the rule of thumb is to order one large pizza per three adults or five children.
Believe it or not, there is a formula for this process, which we discuss below. Alternatively, why not simplify life and just look at our handy chart?
How many pizzas should I order?
The exact number of pizzas to be ordered depends on three criteria: the size of each pizza, the number of adults or children in the group, and their composition (male/female, age, hungriness level). As this can get very complex, we provide some illustrative tables to guide you on your decision.
