Sourdough Hydration Calculator

Calculate true sourdough dough hydration by accounting for the flour and water in your starter, plus total flour, water, and dough weight

Frequently Asked Questions

Why does my starter affect dough hydration?

A starter is itself part flour and part water. Those amounts must be added to the bowl flour and water to find the true total hydration of the dough.

What hydration should I aim for?

Higher hydration gives a more open, airy crumb but stickier dough, while lower hydration is stiffer and easier to handle. Many sourdoughs sit around 70 to 80 percent.
