Why bread flour has its own cups-to-grams number
Bread flour has more protein than all-purpose flour, which gives yeast breads and pizza dough their chew. By volume it is measured the same way as all-purpose flour, so the reference weight per cup is the same. Many bread recipes already list flour in grams; when they don’t, this page gives you the conversion.

How to measure bread flour for this conversion
- Measure it like all-purpose flour: fluff, spoon into the cup, level off. Don’t scoop.
- For bread, small differences in flour change how wet the dough feels. If a recipe gives grams, use them.
- You can swap bread flour and all-purpose flour gram-for-gram; expect a chewier or softer result, not a measurement problem.
- If your dough feels much stiffer or stickier than the recipe describes, check how the flour was measured before adding more water or flour.
