Bread Flour to Water Ratio Calculator

Bread hydration is the ratio of water to flour by weight, expressed as a percentage. 70% hydration means 700g water to 1000g flour. Higher hydration creates open, airy crumb (ciabatta: 80%+), while lower hydration creates tighter crumb (bagels: 55-60%). Most artisan breads use 65-75%.

For most bread recipes, use 60-75% hydration. Sourdough breads typically need 65-85% depending on flour type and desired crumb. Whole wheat flours absorb more water, so you may need 5-10% more. Gluten development and proper kneading become more important at higher hydrations.

Yes significantly. Bread flour (12-14% protein) absorbs more water than all-purpose (10-12%). Whole wheat flour needs 5-10% more water due to bran absorption. Rye flour only needs 50-60% hydration. Always start with the calculated amount and adjust during mixing based on dough feel.

In high humidity, flour can absorb moisture from the air, potentially making doughs wetter. You may need slightly less water. Conversely, in dry climates or winter, doughs may feel tighter and benefit from 2-5% more water. Always judge final dough by feel, not just the calculated numbers.
