Analysis

What is this tool?

Ordering pizza for a group is a high-stakes social puzzle. Too little and people go hungry; too much and you're eating cold crusts for three days. This tool solves the math for you.

We use the 'Standard 8-Slice Large' as our baseline, ensuring your party is perfectly provisioned for maximum satisfaction.

How it works

The Logic

Pizzas = ceil((People * Slices) / 8)

Step-by-Step Method

  1. 1Multiply the number of guests by the desired slices per person.
  2. 2Divide the total slices by 8 (standard large pizza).
  3. 3Round up to the nearest whole pizza.
  4. 4Argue about toppings for 45 minutes.

Example Calculation

A typical scenario for this tool:

Parameters

15 People, 3 Slices each

15 * 3 = 45 total slices

45 / 8 = 5.625

Round up to 6

Final Result

6 Large Pizzas

Frequently Asked Questions

What if someone is a big eater?

Increase the 'Slices per Person' to 4 or 5 for that individual.

Does this include the crust?

Yes, but we assume they eat it. Crust-leavers require 10% more pizza.

What about thin crust?

Thin crust is less filling. Add 1 extra pizza to the total.

Should I get a salad?

No. Just get more pizza.
