Pizza Calculator

PIZZA & BREAD

Find how many pizzas to order for a group based on appetites and slices per pizza.

Usage Tip

Order a mix of toppings so there is something for everyone.

Rounded up
THE MATH
pizzas = round up( people × slices each ÷ slices per pizza )
A typical large pizza yields 8 slices; adults often eat 3 slices.
Round up so nobody runs short, and add an extra pizza for big appetites.

How much dough for a pizza?

The amount of dough sets the thickness of your crust. A good starting point is the surface area of the pizza times a thickness factor of about 2.3–3.4 g per square inch – thin and crisp at the low end, thick and chewy at the high end. The builder above turns a size, style and hydration into a dough ball weight and a full ingredient list.

dough ball = π × (diameter ÷ 2)² × thickness factor
total dough = dough ball × number of pizzas

Pizza area grows with the square of the diameter, so a 16″ is nearly twice the pizza of a 12″ – and needs nearly twice the dough.

Pizza hydration guide

Hydration is the water as a percentage of flour. Lower hydration (55–60%) is easier to handle and crisps up; higher hydration (65–75%) gives a lighter, airier, more open crust but a stickier dough. Most home pizzas live around 60–65%.

Pizza styles guide

Neapolitan

Thin centre, puffy charred rim, soft and foldable. 60–65% hydration, baked very hot (800°F+) for 60–90 seconds.

New York

Large, foldable slices with a crisp-yet-chewy crust, often with a little oil and sugar. 60–63% hydration.

Thin crust

Cracker-thin and crisp, lower hydration and less dough per inch. Rolled rather than stretched.

Detroit

Rectangular pan pizza, thick and airy with crispy cheese edges. High hydration (70–80%).

Sicilian: thick, square, focaccia-like pan pizza with a soft, open crumb and a generously oiled pan.

Pizza uses far less yeast than bread because the dough ferments slowly – often overnight in the fridge – for flavour and digestibility.

Oven temperature recommendations

Hotter is better for most pizza. Crank a home oven to its maximum, preheat for at least 45 minutes with a stone or steel inside, and bake near the top where it is hottest. A pizza steel gets you closest to pizzeria results in a domestic oven.

Proofing and fermentation

Same-day

Bulk rise 2–4 hours at room temperature, then ball and rest 1–2 hours. Use a touch more yeast.

Cold ferment

24–72 hours in the fridge develops far more flavour and a better crust. Use very little yeast (0.2–0.4%).

Pizza stone and steel tips

  • Preheat the stone or steel 45–60 minutes at full heat.
  • Steel conducts faster than stone for a crispier base.
  • Launch on semolina or flour so the pizza slides cleanly.
  • Bake near the top of the oven where it is hottest.

Pizza party planning

Use the calculator above to size a party: people times slices each, divided by slices per pizza. As a rule of thumb, adults eat about 3 slices and a large (14–16″) pizza yields 8–10 slices. Order a mix of toppings and round up so nobody goes hungry.

Frequently asked questions

How much dough for a 14-inch pizza?About 400 g for a standard crust – less for thin, more for thick.
What hydration for pizza dough?Around 60–65% for most styles; 70%+ for airy or pan pizzas.
How much yeast does pizza dough need?Very little – about 0.3–0.5% of the flour for a slow ferment.
How many pizzas for a party?People times about 3 slices each, divided by 8 slices per large pizza, rounded up.
What oven temperature for pizza?As hot as possible – 500–550°F in a home oven, much hotter for Neapolitan.

Baking note: Dough weight recommendations vary with personal taste, style and how you stretch the dough – treat the figures here as a well-tested starting point, not a rule. Flour protein and brand change how much water a dough wants, oven type makes a big difference to bake time and crust, and fermentation method (same-day vs cold) changes the yeast needed. Adjust to your own setup. This is general baking guidance, not a guarantee of results.
