Dough Hydration Calculator

Last updated: June 2026

Flour weight

Water weight

Dough hydration

65%

Higher hydration dough is usually wetter and harder to handle.

Formula

hydration percentage = water weight / flour weight x 100.

About this calculator

The Dough Hydration Calculator works out the water percentage in bread or pizza dough. It helps bakers compare dough feel, adjust recipes, and understand why one dough is stiff while another is sticky and open-textured.

Dough Hydration Calculator method

The calculator applies the visible formula to the values entered. It is designed for practical planning and checking, so keep the assumptions visible when comparing scenarios.

hydration percentage = total water weight / total flour weight x 100
water weight = flour weight x hydration percentage / 100

How to use the Dough Hydration Calculator

Enter total flour weight.
Enter total water or liquid counted as water.
Include levain or starter water if needed.
Review the hydration percentage.
Compare the result with the dough style you want.
Adjust gradually rather than making a large jump.

Worked examples

Pizza dough

Input: 500 g flour and 325 g water

Calculation: 325 / 500 x 100

Result: 65% hydration.

High-hydration focaccia

Input: 600 g flour and 480 g water

Calculation: 480 / 600 x 100

Result: 80% hydration.

When this calculator is useful

Use it as a quick planning tool before editing a recipe, placing an order, choosing packaging, or comparing options. For anything that affects safety, delivery terms, customer pricing, or a commercial commitment, check the final details against the original recipe, supplier, courier, or official source.

Inputs that matter most

Flour type: Strong bread flour and wholemeal flour often handle more water than plain flour.
Handling: Higher hydration doughs can be sticky and may need folds rather than heavy kneading.
Starter: Sourdough starter adds both flour and water to the formula.
Recipe style: Pizza, baguette, sandwich loaf, ciabatta, and focaccia often use different hydration ranges.

Common mistakes to avoid

Check 1: Milk, eggs, honey, and oil change dough feel but are not all pure water.
Check 2: Wholemeal and rye flour absorb water differently.
Check 3: Very wet dough may look wrong if the method expects folds and rest time.
Check 4: Humidity and flour age can affect how much water a dough needs.

Planning notes

Area	What to check
Units	Keep grams, millilitres, centimetres, kilograms, and time units consistent.
Rounding	Round practical kitchen or shipping values after checking the calculated result.
Tolerance	Allow margin for packaging, recipe texture, oven variation, courier rules, or handling space.

Edge cases

Milk, eggs, honey, and oil change dough feel but are not all pure water.
Wholemeal and rye flour absorb water differently.
Very wet dough may look wrong if the method expects folds and rest time.
Humidity and flour age can affect how much water a dough needs.

Limitations

This is general baking information. Judge dough by feel, temperature, time, and recipe method as well as the hydration number.

The calculator measures water-to-flour ratio only.
It cannot predict gluten strength, fermentation speed, or final crumb exactly.

Frequently asked questions

What is dough hydration?

It is water weight as a percentage of flour weight.

Is higher hydration better?

Not always. It depends on flour, technique, and the bread style.

Do I count sourdough starter water?

Yes for accurate formulas, include the flour and water in the starter.

What hydration is pizza dough?

Many pizza doughs sit around 60-70%, but styles vary.

Why is my dough sticky?

High hydration, weak flour, underdeveloped gluten, or warm dough can all make dough sticky.

What does this mean?

This calculator is designed to help you understand the likely number before you make a decision or start an application.

Your result should be checked against official UK guidance, especially if your circumstances include dependants, exemptions, prior leave, or a complex immigration history.

Treat the figure as a planning tool rather than legal advice. Where the answer affects an application deadline or major payment, speak to an authorised adviser.
