Rounding too early
Round final ingredient weights, not every intermediate percentage step.

Bread Recipe Scaling App for Test Bakes and Production
Scaling a bread recipe is not just multiplying everything by a rough number. Serious home bakers, cottage bakers, and micro bakeries need hydration, salt, preferments, and yield to stay consistent as batches grow.
The Baker helps turn a working formula into a repeatable batch workflow on iOS and Android.
Scaling by flour
Scale bread by flour weight
Flour weight is the most stable way to scale a bread formula because baker's percentages are already based on total flour. Choose a new flour target, then calculate every ingredient from its percentage.
Flour-based scaling
new ingredient weight = new total flour * ingredient percentageIf a test loaf uses 1000g flour and 72% water, scaling to 6000g flour gives 4320g water while preserving hydration.
Scaling by yield
Scale by desired loaf or dough yield
Production planning often starts with output: 12 loaves, 24 rolls, or a target total dough weight. In that workflow, the formula needs to back into the required flour and ingredient weights.
For cottage bakers and micro bakeries, this keeps the batch aligned with pan capacity, mixer capacity, order counts, and the number of loaves you actually need to sell or deliver.
Worked example
Move from 2 test loaves to 12 production loaves
Example: a 2-loaf test formula uses 1000g flour, 720g water, 20g salt, and 200g starter. Scale factor: 12 / 2 = 6.
| Ingredient | Test batch | 12-loaf batch |
|---|---|---|
| Flour | 1000g | 6000g |
| Water | 720g | 4320g |
| Salt | 20g | 120g |
| Starter | 200g | 1200g |
Keep ratios intact
Maintain hydration and preferment ratios
When you scale a formula, the final bread should behave like the test batch. That means hydration, salt percentage, enrichment, and preferment percentage need to scale together.
Changing only total flour and water can accidentally alter prefermented flour, starter strength, or dough feel. A production calculator should preserve the whole formula, not just the two largest ingredients.
Common mistakes
Prevent rounding and ingredient errors
Scaling yield but not losses
Production batches may need margin for mixing loss, shaping loss, or order overage.
Breaking preferments
Starter or preferment amounts should stay tied to the full formula, not guessed after the fact.
The Baker workflow
Go from imported recipe to repeatable scaled batch
The Baker combines recipe creation, import, baker's percentage, hydration, timers, and production-oriented tools in one mobile workflow.
- Save or create formulas instead of recalculating from scratch.
- Scale batches while preserving formula relationships.
- Use timers and dough tools alongside the scaled recipe during bake day.

FAQ
Bread recipe scaling FAQ
What is the best way to scale a bread recipe?
For formula-driven bread, scale from total flour weight or baker's percentages so hydration, salt, and preferment ratios stay consistent.
Can I scale by number of loaves?
Yes. Use the desired number of loaves and target loaf size to determine total dough or flour target, then calculate ingredient weights from the formula.
Why do production batches need more careful rounding?
Small rounding choices become larger as batches grow. It is better to keep precise formula math and round only where kitchen measurement requires it.
Is this useful for cottage bakers and micro bakeries?
Yes. The page and app workflow are designed for bakers moving from repeatable test batches to larger production runs.
