Dough Hydration
Find the hydration percentage and final weight of a bread dough.
About Dough Hydration
Hydration divides water weight by flour weight, describing how wet a dough is and therefore how open its crumb will be. Bakers quote hydration rather than absolute amounts so recipes scale and compare reliably across different batch sizes.
Formula
Dough Hydration
Hydration = water / flour x 100; total = flour + water + salt
- hydration
- Water expressed as a percentage of flour weight

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
