Every 100 kcal of whole wheat flour brings 3.9 g of protein. On that measure it ranks 25th of the 111 grains in this database and 533rd of all 796 foods on the site. Measured by weight instead, its 13.2 g per 100 g ranks 9th in its group.
Around 16% of the calories in whole wheat flour come from protein, so it is more of an energy food than a protein food. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Weight for weight, whole wheat flour has 5.3 g of protein for each gram of fat (13.2 g against 2.5 g per 100 g).
Set against barley, another grain entry in the database, a serving carries about 0.5 g more protein (barley has 3.5 g per 1 cup cooked).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving quoted here is measured by volume at 30 g, and it covers about 8% of the 50 g FDA Daily Value for protein.
Keeps the bran and germ, so more protein than white flour.

How much protein is in 100 g of whole wheat flour?
13.2 g. The 1/4 cup serving used on this page weighs 30 g and so carries 4 g.
How much protein do you get per 100 calories of whole wheat flour?
3.9 g. That figure divides its 13.2 g of protein per 100 g by its 340 kcal per 100 g, so it does not depend on serving size.
Is the protein in whole wheat flour complete?
No. On its own, the protein in whole wheat flour is short of at least one essential amino acid; other protein sources across the day fill the gap.
What share of the protein Daily Value is one serving of whole wheat flour?
About 8%. One 1/4 cup serving has 4 g, and the FDA Daily Value for protein is 50 g.
