Master Baker's Math & Hydration
Professional bakers don't use cups; they use Baker's Percentages. This distinctive formula sets the total weight of flour as 100%, and all other ingredients as a percentage of that flour. This makes scaling recipes up (for a bakery) or down (for a single loaf) incredibly easy. Our Bread Hydration Calculator helps you find the perfect water-to-flour ratio for everything from stiff Bagel dough (55%) to airy Ciabatta (80%).
How to Use Baker's Math
- Set Base Flour: Enter the total amount of flour in grams. This is always your 100%.
- Add Ingredients: Input weights for water, salt, yeast, and starters.
- Analyze Hydration:
- 50-60%: Stiff dough (Bagels, Pretzels).
- 60-70%: Standard dough (Sandwich bread, Pizza).
- 70-80%+: Wet/High hydration dough (Sourdough, Ciabatta).
- Scale: To make a larger batch, simply increase the flour weight, and the tool can help you calculate the new ingredient ratios.
Frequently Asked Questions
Why uses grams instead of volume?▼
Volume is inaccurate. One cup of flour can weigh anywhere from 120g to 150g depending on how it's packed. For consistent sourdough starter and bread results, weighing ingredients is non-negotiable.
Does sourdough starter count as hydration?▼
Yes! A standard 100% hydration starter is composed of equal parts flour and water. Professional formulas subtract this flour and water from the base amounts, but for home baking, adding it as a separate ingredient (as shown here) is standard practice.
What is "High Hydration"?▼
Doughs with 75% water or more are considered high hydration. They produce an open crumb with large holes but are sticky and harder to handle. They usually require techniques like coil folds instead of traditional kneading.
