How many grams are in a cup of bread flour?

One US cup of bread flour weighs about 127 grams (4.5 ounces). Half a cup is about 64 g, and one tablespoon is about 7.9 g.

Bread flour is slightly heavier than all-purpose flour because it is milled from higher-protein wheat. If a recipe says bread flour, weighing it keeps your dough hydration consistent.

Bread flour and baker's percentages

Bread flour is milled from higher-protein wheat, usually 12 to 14 percent protein, which builds the strong gluten that gives bagels, pizza crust and sandwich loaves their chew. A cup weighs about 127 g when spooned and leveled, a few grams more than all-purpose flour.

Serious bread recipes are written in baker's percentages, where every ingredient is a percentage of the flour weight. Hydration is the water weight divided by the flour weight. For example, 500 g of bread flour (about 3.9 cups) with 350 g of water is a 70 percent hydration dough.

Why scooping can ruin a dough

Here is how much measuring matters. Four cups of bread flour spooned and leveled weighs about 508 g. Scooped straight from the bag at roughly 145 g per cup, the same four cups weighs about 580 g. Add 355 g of water to each and the first dough is about 70 percent hydration while the second drops to about 61 percent: one is soft and open, the other stiff and tight.

Bread flour and all-purpose flour can be swapped one for one by weight, though bread flour may want slightly more water. Bread flour also makes chewier cookies and a crisper pizza crust, which is why some bakers use it on purpose in recipes that call for all-purpose. In the UK and Canada, flour sold as strong white or strong bread flour is the closest match.

Frequently asked questions

How many cups is 100 grams of bread flour?

100 g of bread flour is about 0.79 cups.

How many grams is a tablespoon of bread flour?

About 7.9 g, based on 127 g per cup and 16 tablespoons per cup.

How many cups is 1 kilogram of bread flour?

A kilogram is about 7⅞ cups. Half a kilogram (500 g) is about 3.9 cups.

What does hydration mean in bread baking?

It is the weight of the water divided by the weight of the flour, shown as a percentage. A 65 to 70 percent dough is a typical sandwich loaf, while open-crumb artisan breads often run 75 percent or higher.

Can I use bread flour instead of all-purpose flour?

Yes, by weight. Expect a chewier, more elastic result, and add a splash more water if the dough feels stiff.
