How to measure rye flour

Rye flour is denser and stickier than wheat flour, yet it measures lighter by volume.

Because a cup measures volume rather than weight, the most reliable way to measure rye 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.

Rye flour conversions: FAQ

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

A cup measures volume, not weight. Rye flour is less dense than water (102 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.
