Step-by-step

  1. Hydration = (water / flour) ร— 100 = (325 / 500) ร— 100 = 65.00%.

How to use this calculator

  • Enter flour and water weights in grams.
  • Read the hydration percentage and the style classification.

About this calculator

Pizza dough hydration is the ratio of water weight to flour weight, expressed as a percentage (baker's percentages). Different pizza styles target distinct hydration ranges: classic Neapolitan and NY-style cluster around 58-62%, Roman al taglio and Detroit-style push to 70%+, and Roman in teglia / focaccia exceeds 80%. Higher hydration means a more open crumb, a softer chew, and a longer fermentation โ€” but also a stickier, harder-to-handle dough that benefits from autolyse and stretch-and-fold techniques.

What this calculator does

This calculator returns the hydration percentage โ€” water weight divided by flour weight times 100 โ€” of a pizza-dough formula and classifies it against the canonical style ranges (Neapolitan ~58-62%, NY ~60-65%, Detroit ~68-75%, Roman in teglia 75%+, focaccia 80%+). Hydration is the single most important variable in dough texture: too low and the crumb is dense, too high and the dough is unmanageable for the pan and fermentation method.

How it works โ€” the formula

Hydration % = (water_weight / flour_weight) ร— 100

In baker's percentages, flour is always 100% and every other ingredient is reported as a percentage of the flour weight. Hydration is the water-to-flour ratio in that scheme. Style ranges come from practitioner sources (Modernist Cuisine, Forkish, Forno Bravo) and Italian DOC standards (Vera Pizza Napoletana).

Worked examples

Example 1
Neapolitan starter
Inputs:
flour=500g, water=325g
Output:
65% hydration โ†’ NY-style modern / Roman tonda

Slightly above the strict Neapolitan range; still neutral-territory for thin-crust pizza.

Example 2
Classic Vera Pizza Napoletana
Inputs:
flour=1000g, water=600g
Output:
60% hydration โ†’ Neapolitan / NY-style

AVPN-spec dough.

Example 3
Roman in teglia (pan pizza)
Inputs:
flour=500g, water=400g
Output:
80% hydration โ†’ Roman in teglia / focaccia

Wet dough handled with bench scrapers and oiled fingers; needs strong bread flour.

When to use this vs other tools

Use this when planning a pizza-dough formula. For other dough hydration questions, the bread/sourdough tools specialize.

  • Bread Hydration

    Use for non-pizza loaves where lean-dough hydration ranges differ slightly from pizza ranges.

  • Sourdough Hydration

    Use when factoring a sourdough starter's flour and water into the total dough hydration.

  • Pizza Dough per Pizza

    Use to scale from total-dough weight to individual pizza ball weight (Neapolitan ~240-280 g; NY ~340-400 g).

  • Recipe Scaler

    Use to scale flour and water proportionally when changing yield โ€” hydration % stays the same.

Authority note

Associazione Verace Pizza Napoletana (AVPN) + Modernist Cuisine

AVPN codifies the Neapolitan-style dough hydration range (~58-65%). The wider range of pizza styles classified here draws on Modernist Cuisine, Forkish, and the broader baker's-percentage convention used worldwide.

Limitations

  • Hydration is one of several variables; salt, yeast, fermentation time, and flour protein content also drive final texture.
  • Style classifications are practitioner heuristics โ€” there is no global rule that "X% is style Y", just clustered conventions.
  • Doesn't account for sourdough starter contribution; for sourdough use the dedicated tool to fold starter flour/water into the total.
  • Pre-ferments (biga, poolish) shift the effective hydration; this calculator targets straight-dough recipes.

Recipe outcomes depend on flour, technique, temperature, and oven. Use the hydration figure as a planning anchor and adjust to your environment.

Frequently asked

Baker's percent normalizes all ingredients to the flour weight (=100%). It makes recipes scalable to any batch size and comparable across formulas regardless of yield.
