Making pizza from scratch? The math is easier than the kneading.
Use this free Pizza Dough Calculator to calculate the exact ingredients you need for perfect pizza dough. Enter your flour amount, hydration percentage, and number of pizzas to get instant results for water, salt, total dough weight, and individual doughball sizes. Works with both metric (grams) and imperial (ounces) measurements.
This pizza dough hydration calculator helps you master the art of pizza making by calculating the perfect water to flour ratio. Because sticky dough is a nightmare, and dry dough is a crime against pizza.

This calculator helps you:
Perfect for home bakers, pizza enthusiasts, and anyone who wants to make restaurant-quality pizza dough at home.

Pizza dough hydration is the percentage of water relative to flour weight. It's one of the most important factors in pizza making, affecting texture, crispiness, and workability.
Hydration % = (Water Weight ÷ Flour Weight) × 100
For example, if you have 500g of flour and 325g of water: (325 ÷ 500) × 100 = 65% hydration.
The calculator uses these formulas:
Most home bakers use 60-65% hydration for a good balance of workability and texture.

Pizza dough hydration is the percentage of water relative to flour weight. For example, 65% hydration means you use 65g of water for every 100g of flour. It's the most important factor in determining dough texture, crispiness, and workability.
The amount of water depends on your desired hydration level. For 65% hydration (standard), use 325g of water for 500g of flour. For 60% hydration, use 300g of water for 500g of flour. Use our calculator to find the exact amount based on your flour and hydration percentage.
60-65% hydration is ideal for most home bakers. It's easy to work with and produces a good balance of crispy and chewy texture. Lower hydration (55-60%) creates crispier, cracker-like crusts, while higher hydration (70%+) creates softer, more Neapolitan-style crusts but requires more skill to handle.
For a standard 12-inch pizza, you typically need 250-300g (8-10 oz) of dough. For a 14-inch pizza, use 350-400g (12-14 oz). Our calculator automatically divides the total dough by the number of pizzas to give you the exact doughball weight per pizza.
To calculate hydration: (Water Weight ÷ Flour Weight) × 100. For example, if you have 500g flour and 325g water: (325 ÷ 500) × 100 = 65% hydration. Our calculator does this automatically when you enter flour and water amounts.
No, pizza dough is not a 1:1 ratio. Most pizza dough uses 60-65% hydration, meaning 60-65g of water per 100g of flour. A 1:1 ratio (100% hydration) would be extremely wet and difficult to work with, more like a batter than dough.
Standard salt percentage is 2% of flour weight. For 500g of flour, that's 10g of salt. You can adjust between 1.5-2.5% based on taste preference. Salt affects flavor, fermentation speed, and gluten development.
Yes! Adjust the hydration percentage based on your pizza style: 55-60% for thin/crispy Roman style, 60-65% for standard American pizza, 65-70% for Neapolitan style, and 70%+ for high-hydration artisan pizzas.
We roast the numbers, not you. But if your dough hydration is below 50% or above 80%, you're either making crackers or soup. Find the middle ground.
Calculations are based on standard pizza dough formulas. Actual results depend on flour type, room temperature, fermentation time, and your kneading technique. Practice makes perfect—and sticky hands are part of the process.
