How to measure bread flour

Bread flour has more protein than all-purpose flour, but it weighs about the same per cup.

Because a cup measures volume rather than weight, the most reliable way to measure bread flour is with a digital kitchen scale. If you are working from cups, keep your technique consistent every time so your results are repeatable. For more, see our guide on baking by weight versus volume.

Substitutes for bread flour

Equal all-purpose flour, optionally with 1 tsp vital wheat gluten per cup (King Arthur Baking)
Plain AP flour works for most home bread recipes — the dough is slightly less elastic and the crumb a bit less chewy. The vital wheat gluten addition brings it closer to bread flour's protein content (12–14%).

Bread flour conversions: FAQ

Why doesn't a cup of bread flour weigh the same as a cup of water?

A cup measures volume, not weight. Bread flour is less dense than water (120 g versus 237 g per cup), so the same volume has a different weight. Weighing in grams is the most accurate way to measure it.
