Pizza Dough Calculator Guide: Hydration, Flour Ratios & Fermentation Tips
Quick Answer
- *A basic pizza dough is flour (100%), water (60–65%), salt (2–3%), yeast (0.1–1%) by baker's percentage.
- *One 12-inch Neapolitan pizza needs about 250–280g of dough.
- *Hydration (water-to-flour ratio) is the single biggest factor in crust texture.
- *Cold-fermenting for 24–72 hours dramatically improves flavor and digestibility.
Baker's Percentages: The Foundation of Dough Math
Professional bakers and pizzaiolos don't measure in cups. They use baker's percentages, where every ingredient is expressed as a percentage of the total flour weight. Flour is always 100%. Everything else is relative to it.
This system, codified by the American Institute of Baking and used worldwide, makes scaling trivial. Want to make 8 pizzas instead of 4? Double the flour weight, and every other ingredient doubles automatically.
| Ingredient | Baker's % | For 4 Pizzas (1000g flour) | For 8 Pizzas (2000g flour) |
|---|---|---|---|
| Flour | 100% | 1000g | 2000g |
| Water | 62% | 620g | 1240g |
| Salt | 2.5% | 25g | 50g |
| Yeast (instant dry) | 0.2% | 2g | 4g |
| Olive oil (optional) | 2% | 20g | 40g |
Total dough weight per ball: approximately 267g, enough for a 12-inch Neapolitan-style pizza. The Associazione Verace Pizza Napoletana (AVPN) specifies dough balls of 200–280g for their certified restaurants.
Hydration: The Most Important Variable
Hydration is the percentage of water relative to flour. It controls everything — how the dough handles, how it bakes, and the final texture. According to the AVPN's official protocol document, Neapolitan pizza dough should be 55.5–62.5% hydration.
| Pizza Style | Hydration Range | Texture Result |
|---|---|---|
| Neapolitan | 55–65% | Soft, supple, leopard-spotted char |
| New York | 60–65% | Foldable, slightly chewy |
| Roman al taglio | 75–85% | Light, airy, crisp bottom |
| Detroit | 70–80% | Thick, focaccia-like, airy crumb |
| Thin & crispy | 50–55% | Cracker-like, snappy |
Higher hydration doughs are stickier and harder to handle, but they produce a more open, airy crumb. If you're just starting, 60% is a forgiving sweet spot. According to Modernist Cuisine (Myhrvold et al.), water activity in dough also affects Maillard browning — higher hydration doughs brown faster in the oven.
Flour Selection: Protein Matters
The protein content of your flour determines how much gluten the dough develops. More gluten means more structure, chew, and ability to trap gas bubbles. The Wheat Quality Council publishes annual protein data for North American wheat varieties:
| Flour Type | Protein Content | Best For |
|---|---|---|
| Italian Tipo 00 (Caputo) | 12–13% | Neapolitan, high-heat ovens |
| Bread flour (King Arthur) | 12.7% | New York style, home ovens |
| All-purpose flour | 10–12% | Quick weeknight pizza |
| Whole wheat flour | 13–14% | Blending (10–30% mix) |
Tipo 00 flour is finely milled and absorbs less water than bread flour. If substituting bread flour for 00, increase hydration by 2–3 percentage points. According to Caputo's product specifications, their Pizzeria flour has a W value (gluten strength index) of 260–280, optimized for 24-hour fermentation.
Dough Ball Sizes by Pizza Style
| Pizza Size | Diameter | Dough Ball Weight |
|---|---|---|
| Personal Neapolitan | 10” | 200–220g |
| Standard Neapolitan | 12” | 250–280g |
| New York slice | 18” | 500–600g |
| Detroit pan (10×14”) | — | 500–600g |
| Roman al taglio (sheet) | Full sheet pan | 700–900g |
Fermentation: Time Is Flavor
Fermentation is where dough transforms from bland paste to complex, flavorful crust. During fermentation, yeast produces CO2 (for rise) and ethanol plus organic acids (for flavor). Enzymes break down starches into simpler sugars that caramelize during baking.
According to research published in the Journal of Cereal Science (Poutanen et al., 2020), long fermentation also breaks down FODMAPs — fermentable carbohydrates that cause digestive discomfort. A 48-hour cold fermentation reduces FODMAP content by up to 90%, potentially making pizza more digestible for sensitive individuals.
| Fermentation Method | Temperature | Duration | Yeast Amount (IDY) |
|---|---|---|---|
| Same-day (room temp) | 72–75°F (22–24°C) | 6–12 hours | 0.5–1% |
| Overnight (room temp) | 68–72°F (20–22°C) | 12–24 hours | 0.1–0.3% |
| Cold ferment (fridge) | 38–40°F (3–4°C) | 24–72 hours | 0.1–0.2% |
| Extended cold ferment | 38–40°F (3–4°C) | 72–120 hours | 0.05–0.1% |
The inverse relationship between yeast and time is key. Less yeast means slower fermentation, which means more time for flavor compounds to develop. The AVPN standard allows 0.1–0.3% fresh yeast (roughly half that for instant dry yeast) with an 8–24 hour room-temperature fermentation.
Salt: Small Percentage, Big Impact
Salt typically runs 2–3% in baker's percentages. It does three things: strengthens gluten, controls fermentation speed, and adds flavor. According to the American Institute of Baking, removing salt entirely causes dough to ferment 30–40% faster and produces a slack, sticky texture with bland taste.
Fine sea salt dissolves more readily than coarse kosher salt. If using Diamond Crystal kosher salt (which is less dense), increase the weight by about 50% compared to fine salt to achieve the same salinity.

What hydration should I use for pizza dough?
It depends on the style. Neapolitan pizza uses 55–65% hydration for a soft, pliable dough that puffs in a 900°F oven. New York style runs 60–65% for a foldable, slightly chewy crust. Detroit and Roman-style pan pizzas go higher at 70–80% for an airy, focaccia-like crumb. Start at 60% and adjust from there.
What are baker's percentages?
Baker's percentages express every ingredient as a percentage of the total flour weight. Flour is always 100%. If a recipe uses 1000g flour and 650g water, the hydration is 65%. Salt at 30g is 3%. This system makes scaling to any batch size trivial — just change the flour weight and multiply.
How much dough do I need per pizza?
A standard 12-inch Neapolitan pizza uses a 250–280g dough ball. A 14-inch New York pie needs about 350–400g. For a thick Detroit-style in a 10×14 pan, use 500–600g. The exact amount varies by how thin you stretch and whether the crust has a raised rim.
How long should pizza dough ferment?
Room temperature (72°F/22°C) bulk fermentation typically takes 8–24 hours depending on yeast amount. Cold fermentation in the fridge (38–40°F) takes 24–72 hours and develops more complex flavors. The AVPN specifies 8–24 hours at room temperature for authentic Neapolitan pizza.
What flour is best for pizza dough?
For Neapolitan style, use Italian Tipo 00 flour (like Caputo Pizzeria) with 12–13% protein. For New York style, bread flour with 12–14% protein gives the right chew. All-purpose flour (10–12% protein) works for home ovens but produces a less structured crust. The protein content determines gluten development, which affects texture and rise.
