About the Baking Hydration Calculator

Baking Hydration is treated here as a quantitative relation between Flour Amount, Water Amount, Starter/Poolish and Starter Hydration and Overall Hydration%, Total Dough Weight and Dough Classification.

The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.

Formula basis:
Hydration% = Water grams / Flour grams x 100

Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

Hydration% = Water grams / Flour grams x 100

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

Worked Examples

Example 1: Classic sourdough: 500g flour, 375g water, 100g starter (100% hydration)

Inputs

flour_g: 500 water_g: 375 starter_g: 100 starter_hyd: 100
Overall Hydration%: 77.3%. Total Dough Weight: 975 g. Dough Classification: Wet dough (artisan, baguette)

With Flour Amount = 500, Water Amount = 375, Starter/Poolish = 100 and Starter Hydration = 100 as the stated inputs, the result is Overall Hydration% = 77.3%, Total Dough Weight = 975 g and Dough Classification = Wet dough (artisan, baguette). Each value corresponds to the declared output fields.

Example 2: Sandwich bread: 500g flour, 325g water (no starter)

Inputs

flour_g: 500 water_g: 325 starter_g: 0 starter_hyd: 0
Overall Hydration%: 65%. Total Dough Weight: 825 g. Dough Classification: Standard dough (sandwich bread)

With Flour Amount = 500, Water Amount = 325, Starter/Poolish = 0 and Starter Hydration = 0 as the stated inputs, the result is Overall Hydration% = 65%, Total Dough Weight = 825 g and Dough Classification = Standard dough (sandwich bread). Each value corresponds to the declared output fields.

Example 3: Ciabatta: 500g flour, 425g water, high hydration

Inputs

flour_g: 500 water_g: 425 starter_g: 0 starter_hyd: 0
Overall Hydration%: 85%. Total Dough Weight: 925 g. Dough Classification: High-hydration (ciabatta, some sourdough)

With Flour Amount = 500, Water Amount = 425, Starter/Poolish = 0 and Starter Hydration = 0 as the stated inputs, the result is Overall Hydration% = 85%, Total Dough Weight = 925 g and Dough Classification = High-hydration (ciabatta, some sourdough). Each value corresponds to the declared output fields.

Example 4: New York bagels: 500g flour, 280g water, low hydration

Inputs

flour_g: 500 water_g: 280 starter_g: 0 starter_hyd: 0
Overall Hydration%: 56%. Total Dough Weight: 780 g. Dough Classification: Stiff dough (bagels, pretzels)

With Flour Amount = 500, Water Amount = 280, Starter/Poolish = 0 and Starter Hydration = 0 as the stated inputs, the result is Overall Hydration% = 56%, Total Dough Weight = 780 g and Dough Classification = Stiff dough (bagels, pretzels). Each value corresponds to the declared output fields.

Common Use Cases

  • Calculate hydration for sourdough bread
  • Use baker's percentages for bread recipes
  • Adjust dough consistency by changing water ratio
