What is a Dough Hydration?
A Pizza Dough Hydration Calculator finds the water-to-flour ratio (hydration percentage) of a dough recipe, or works in reverse to tell you exactly how much water to add for a target hydration level. Enter your flour and water weights to get the hydration percentage, or switch to reverse mode, enter your flour weight and a target hydration percentage, and get the exact water weight needed.
Hydration percentage is the standard way bakers describe how wet or dry a dough is, independent of batch size — it's simply water weight as a percentage of flour weight. A 65% hydration dough uses 65g of water per 100g of flour, whether you're making one small ball or a dozen.
Hydration % = (Water Weight ÷ Flour Weight) × 100
How to use this Dough Hydration calculator
- Enter your flour weight in grams.
- Enter your water weight in grams to calculate hydration percentage — or switch to reverse mode and enter a target hydration percentage instead to find the water weight needed.
- Read your hydration percentage, along with the water weight and total dough weight.
- Compare against your target style (e.g. 58-65% for Neapolitan-style) and adjust water weight as needed.
Formula & Methodology
Hydration % = (Water Weight ÷ Flour Weight) × 100 Reverse: Water Weight = Flour Weight × (Target Hydration % ÷ 100) Total Dough Weight = Flour Weight + Water Weight This calculator uses the standard two-ingredient baker's percentage definition of hydration (water relative to flour only). Real dough recipes typically also include salt, yeast, and sometimes oil or sugar, which add a small amount of additional weight (usually 2-3% of flour weight combined) not reflected in this simplified calculation — for a full ingredient-by-ingredient breakdown including these additions, use a Baker's Percentage Calculator instead.
Frequently Asked Questions
Dough hydration is the weight of water in a recipe expressed as a percentage of the flour weight — it's the most common way bakers describe how wet or dry a dough is, independent of batch size. A 65% hydration dough contains 65g of water for every 100g of flour, regardless of whether you're making a small or large batch.
Hydration % = (Water Weight ÷ Flour Weight) × 100. For 500g of flour and 325g of water, hydration is (325 ÷ 500) × 100 = 65%. This calculator performs that division automatically, or works in reverse — enter a target hydration percentage and flour weight to find the exact water weight needed.
Classic Neapolitan-style pizza dough typically sits around 58-65% hydration, New York-style is often 60-65%, and higher-hydration styles like focaccia or some artisan Neapolitan doughs can run 70% or higher for a more open, airy crumb. Lower hydration (55-60%) produces a firmer, easier-to-handle dough better suited to beginners.
More water relative to flour means more free moisture in the dough that hasn't been fully absorbed by the flour's starches and proteins, which makes the dough feel wetter and stickier to handle. High-hydration doughs (70%+) often require wet hands or a bench scraper for shaping rather than dry-flour dusting, which would otherwise throw off your calculated hydration.
Traditional baker's percentage hydration typically refers to water content specifically, though some recipes calculate 'total hydration' including other liquids like oil, milk, or eggs. This calculator uses the standard water-to-flour definition; if your recipe includes significant other liquids, you may want to account for them separately using a full baker's percentage breakdown.
To raise hydration, add water in small increments (5-10g at a time) and knead thoroughly to let the flour absorb it before adding more — jumping too high too fast makes dough unmanageably sticky. To lower hydration, add flour gradually in the same way. Use this calculator's reverse mode to find the exact water weight for your new target percentage before adjusting.
Low-hydration dough (under 55%) tends to be dense, tight, and harder to stretch thin without tearing, often producing a crackery rather than airy crust. Most standard home-oven pizza recipes stay in the 58-65% range specifically to balance easy handling with a good chewy-to-airy crumb structure.
Percentage-based (baker's percentage) formulas scale perfectly to any batch size and remain consistent regardless of flour type or measuring method, while volume measures like cups vary significantly based on how the flour is scooped and packed. A gram-based hydration percentage lets a recipe be reliably doubled, halved, or scaled to any dough ball count.
Higher-protein flours (like bread flour or '00' pizza flour) can typically absorb more water and support higher hydration doughs than lower-protein all-purpose flour, since more gluten-forming protein means more capacity to trap and structure water. If a recipe formulated for '00' flour feels too wet with all-purpose flour, reducing hydration slightly can help.
Yes — hydration percentage is a general baking concept used across pizza, bread, and other yeasted doughs, not specific to pizza alone. Enter your recipe's flour and water weights (or target hydration) the same way regardless of what you're baking; just note that ideal hydration ranges differ by bread type (rustic artisan loaves often run higher than sandwich bread, for example).
Water Weight = Flour Weight × Hydration % = 1000g × 0.65 = 650g. Use this calculator's reverse mode by entering your flour weight and target hydration percentage to get this water weight instantly for any flour quantity.
For a basic two-ingredient calculation (flour and water only), yes — total dough weight here is simply flour weight plus water weight. Real dough recipes also include salt, yeast, and sometimes oil, which add a small additional weight not captured in this simplified two-ingredient hydration calculation; those additions are typically only 2-3% of flour weight combined and have minimal effect on the overall hydration figure.
