Pizza Dough Calculator

Pizza Dough Calculator: calculate pizza dough for cooking and nutrition. Practical tips and worked examples.

A bread hydration calculator determines the water content of a bread dough as a percentage of the flour weight, using baker's percentages — a professional baking standard where every ingredient is expressed as a percentage of total flour weight rather than a fraction of the total recipe. Hydration directly determines dough handling characteristics, crumb structure, crust texture, and fermentation behaviour. Understanding hydration is the foundational skill of bread baking. Recipe Scale Calculator andIngredient Weight Calculator are essential tools for managing fermentation and recipe scaling.

Hydration ranges from approximately 55–65% for firm, easy-to-handle doughs (bagels, pretzels, pasta) through 65–75% for standard sandwich loaves, up to 80–95%+ for high-hydration sourdoughs and ciabatta. Each 5% increase in hydration significantly changes dough behaviour — higher hydration produces a more open, irregular crumb and requires more technical handling skills such as stretch-and-fold rather than traditional kneading.

Enter the total flour weight in grams — this is always 100% in baker's percentages.
Enter the total water weight in grams.
If using sourdough starter, enter its weight and hydration — the calculator accounts for the flour and water it contributes.
Hydration % = (Total water ÷ Total flour) × 100.
Adjust your target hydration by changing the water quantity — increase for a more open crumb, decrease for easier handling.
Compare your hydration to the range guide to understand the expected handling and crumb characteristics.

Bread hydration formula

Hydration % = (Water weight ÷ Flour weight) × 100

Baker's percentage for any ingredient = (Ingredient weight ÷ Flour weight) × 100

Sourdough starter adjustment: Starter contains both flour and water. At 100% hydration starter, half the starter weight is flour and half is water.

Worked example: 500g flour, 375g water, 100g starter (100% hydration). Starter contributes 50g flour + 50g water. Total flour = 500 + 50 = 550g. Total water = 375 + 50 = 425g. True hydration = 425 ÷ 550 × 100 = 77.3%.

Hydration ranges and their characteristics

What to expect at each hydration level

Hydration guide: 55–65% — stiff dough; bagels, pasta, pretzels; easy to shape; tight crumb; 65–72% — standard loaf; sandwich bread, baguette; manageable handling; even crumb; 72–78% — slightly slack; country loaves, white sourdough; requires confident handling; more open crumb; 78–85% — wet dough; ciabatta, high-hydration sourdough; stretch-and-fold technique required; very open irregular crumb; 85%+ — extremely wet; expert-level only; almost pourable; requires bannetons and overnight cold retard for shaping.

Food tips and best practices

Start at 70% hydration and build confidence before moving to higher hydrations — the technical skills required increase significantly above 75%.
Whole wheat and rye flours absorb more water than white flour — increase hydration by 5–10% when substituting for white flour.
Autolyse (resting flour and water before adding salt and levain for 20–60 minutes) significantly improves dough extensibility and reduces final mixing time.
Dough temperature matters as much as hydration — target a final dough temperature of 24–26°C for optimal fermentation rate.
High-hydration doughs are much easier to manage when thoroughly chilled — an overnight cold retard in the refrigerator after shaping dramatically improves handling and scoring.

A 5% increase in hydration (e.g. from 70% to 75%) typically adds approximately 25g of water to a 500g flour recipe — a seemingly small change that significantly alters dough behaviour.
Professional bakers standardize on baker's percentages rather than ratios, making recipes scalable from a single loaf to hundreds of kilograms without recalculation.
Sourdough bread typically ferments for 12–24 hours total at temperatures of 24–26°C — hydration level affects fermentation speed, with higher hydration accelerating enzymatic activity.
Salt is typically 1.8–2.2% of flour weight in baker's percentages — equivalent to approximately 10g salt per 500g flour in a standard loaf.

Common mistakes to avoid

Not accounting for starter hydration when calculating true dough hydration — a 100g starter at 100% hydration contributes 50g flour and 50g water to your totals.
Adding all the water at once when mixing high-hydration doughs — reserve 10–15% of water and add it gradually during mixing to allow the flour to fully hydrate first.
Ignoring ambient temperature and humidity — high summer temperatures accelerate fermentation; reduce water temperature or shorten bulk fermentation accordingly.
Confusing baker's percentage with standard percentage — a recipe with 500g flour and 375g water is 75% hydration in baker's terms, not 42.8% of total dough weight.

Bread hydration calculations follow baker's percentage conventions established in professional baking. Food safety requirements for bread production — including internal temperature minimums, allergen labeling, and premises hygiene — are governed by national food safety legislation and the FDA Food Safety Modernization Act (FSMA).
