The right amount of pizza, every time

A free calculator for figuring out exactly how many pizzas to order for any group, any size, any occasion.

The problem

Birthday parties, sports teams, office lunches, church potlucks — the question is always the same: how many pizzas?

Most people guess. They either order too much and waste money, or too little and someone goes hungry. The calculators that already exist online are buried in ads, want your email, or spit out a vague number with no way to customize it.

How it works

Simple math, but the details matter. The calculator adjusts for pizza size, appetite level, and the mix of toppings your group actually wants.

The math

2.75

pizzas for
your party

Adjust slices per person for your crowd — 2.25 for little kids, 2.75 for a mixed group, 3+ for hungry teenagers. The type breakdown uses percentages you set, and one type absorbs rounding so the total is always exact.

Why it exists

Every pizza calculator I found was either bloated with ads, wanted my email, or gave a vague answer with no way to customize anything. I just wanted to type a number, see a result, and place my order.

So I built the tool I wanted. It's free and it'll stay free.
