How to measure all-purpose flour

Spoon the flour into the cup and level it off — scooping straight from the bag packs it down and can add up to 20% more flour than a recipe intends.

Because a cup measures volume rather than weight, the most reliable way to measure all-purpose 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 all-purpose flour

1 cup AP = 1 cup bread flour (or vice versa) (King Arthur Baking)
Higher-protein bread flour yields chewier results; expect a slightly tougher crumb in cakes and biscuits. Acceptable in most recipes outside delicate pastry.
1 cup AP = ⅞ cup cake flour + 2 tbsp cornstarch (for cake-flour recipes) (America's Test Kitchen)
Use when a recipe calls for cake flour and you only have AP; for the reverse, equal parts bread + cake flour by weight approximates AP.

All-purpose flour conversions: FAQ

Why doesn't a cup of all-purpose flour weigh the same as a cup of water?

A cup measures volume, not weight. All-purpose 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.
