About measuring all-purpose flour
All-purpose flour is the workhorse of most kitchens, and one US cup of it weighs about 125 grams when spooned and levelled. Because flour compresses so easily, the way you fill the cup matters more than for almost any other ingredient. Scoop straight from the bag and you can pack in 150 grams or more, which is why so many cakes and cookies come out dense or dry. Weighing removes that guesswork entirely.
Spoon flour into the cup and level it off. Scooping straight from the bag packs in extra grams.
Frequently asked questions
How many grams is 1 cup of all-purpose flour?

Why do recipes differ on the weight of a cup of flour?
Flour is compressible, so its weight depends on how it is measured. Values between 120 and 130 grams per cup are all common. CupsToGrams uses 125 grams, the spoon-and-level standard.
Is bread flour the same weight as all-purpose flour?
They are close. Bread flour sits a touch higher at around 127 grams per cup because of its slightly denser protein structure, but for most recipes you can treat them the same.
