Dough Hydration Calculator
The Dough Hydration Calculator computes the baker's percentage (water-to-flour ratio) for bread, pizza, and pastry doughs. Enter flour and water weights to find hydration level, or set a target hydration to calculate how much water your recipe needs.

What is Dough Hydration?
Dough hydration is the ratio of water to flour by weight, expressed as a baker's percentage. A 65% hydration dough uses 65 grams of water for every 100 grams of flour. Higher hydration creates lighter, more open crumbs (like ciabatta at 80%+), while lower hydration produces denser, shaping-friendly doughs (bagels at 55-58%).
Baker's percentages express every ingredient relative to flour weight (flour is always 100%). Hydration is the most critical ratio — it determines dough texture, crumb structure, oven spring, and handling difficulty. Mastering hydration is key to consistent baking.
Formules et Équations utilisées
Ce calculateur s'appuie sur 5 équations fondamentales :
1 Hydration Percentage ▼
325g water with 500g flour: Hydration = (325/500) × 100 = 65%.
2 Water Needed for Target Hydration ▼
For 70% hydration with 1000g flour: Water = 1000 × 0.70 = 700g.
3 Flour Needed for Target Hydration ▼
For 65% hydration with 390g water: Flour = 390 / 0.65 = 600g.

Foire Aux Questions
What is the best hydration for bread? ▼
For beginners, 65-68% is manageable. Sandwich bread: 60-65%. Artisan loaves: 68-75%. Ciabatta and focaccia: 75-85%. Higher hydration gives bigger holes but is harder to handle.
What is baker's percentage? ▼
Baker's percentage expresses each ingredient as a percentage of the total flour weight. Flour is always 100%. So 65% hydration means 65g water per 100g flour, 2% salt means 2g salt per 100g flour.
Does whole wheat flour need more water? ▼
Yes. Whole wheat flour absorbs about 5-10% more water than white flour due to bran particles. If using 100% whole wheat, add 5-10 percentage points to your hydration target.
What hydration is pizza dough? ▼
Neapolitan pizza: 58-62%. New York style: 62-66%. Sicilian/pan: 70-75%. Higher hydration creates a lighter, more bubbly crust but is stickier and harder to shape.
How does hydration affect oven spring? ▼
Higher hydration dough generally has more oven spring because more water converts to steam during baking. However, above 80%, the dough may spread laterally rather than rising, especially without proper shaping and tension.
