Calculate exact ingredients using baker's percentages
Enter your target dough weight, hydration, starter percentage, and salt percentage to get exact gram amounts. Accounts for flour and water contributed by the starter (assumed 100% hydration). Every gram matters in sourdough. Use a scale.

Sourdough baking is precise. A 5% change in hydration transforms the dough from manageable to impossibly sticky. Baker's percentages (where flour = 100%) make scaling any recipe trivial, but only if you measure by weight. A $15 kitchen scale is the single best investment for sourdough baking.
