How to Measure Flour
All-purpose flour weighs 120 grams per cup when it is spooned into the cup and levelled off — but scooping the cup straight from the bag can pack in 20 percent more and ruin the crumb of a cake, which is why the method matters as much as the number.
The spoon-and-level method, step by step
Spoon-and-level is the method behind every flour weight on GramChef, and it has three steps. First, fluff the flour in its bag or container with a spoon or whisk, because flour settles and compacts in storage. Second, spoon the fluffed flour into the measuring cup until it heaps above the rim, without shaking the cup or pressing the flour down. Third, level the top by sweeping the flat back of a knife across the rim, letting the excess fall back into the container.
Done this way, a cup of all-purpose flour weighs 120 g, and a cup of bread flour weighs the same. The method takes a few seconds longer than scooping and gives the same result every time, because the flour enters the cup at a consistent, uncompacted density.
Why scooping from the bag gives the wrong weight
Scooping pushes the cup through the flour and packs it against the side of the bag, compressing far more flour into the cup than the recipe expects. GramChef's methodology notes that scooping can add 20 percent or more to the weight. A cup of all-purpose flour that should weigh 120 g can come out at around 145 g when scooped.
That extra flour is a common cause of dry cakes, dense bread and dough that needs more liquid than the recipe states. The recipe is rarely at fault; the flour was simply measured at a higher density than the recipe assumed.
Sifted flour and recipe wording
Sifting changes the weight of a cup because it loosens the flour and mixes in air, so a cup of sifted flour weighs less than a cup of unsifted flour. Recipe wording decides when to sift. '1 cup sifted flour' means sift first, then spoon and level the sifted flour into the cup. '1 cup flour, sifted' means measure the flour first, then sift it.
All of GramChef's flour weights are for unsifted flour, spooned and levelled. When a recipe calls for sifted flour and gives no weight, weighing the unsifted flour and then sifting it delivers the intended amount more reliably than measuring the airy sifted flour by volume.
Different flours, different weights
A cup is a volume, so each flour fills it at a different density. GramChef lists a US cup of all-purpose flour at 120 g, whole wheat flour at 113 g, cake flour at 113 g, almond flour at 96 g and coconut flour at 128 g. Swapping one flour for another cup-for-cup changes the weight of flour in the recipe before any other difference between the flours is even considered.
Tablespoon measures follow the same pattern, at 7.5 g per tablespoon for all-purpose flour against 6 g for almond flour. For a single spoonful the difference is small, but across the two or three cups in a typical cake it is large enough to change the result.
When only a scale settles it
Some situations leave volume measuring with no reliable answer. Small amounts, such as the flour for a roux or a dusting, are hard to spoon consistently. Bread and pastry recipes, where flour is the ingredient everything else is balanced against, punish even small errors. Any recipe that prints both cups and grams is quietly asking to be weighed.
A basic digital scale removes the questions. Flour is weighed straight into the mixing bowl, the bowl is zeroed between additions, and the 120 g the recipe means is the 120 g that goes in — no method, no wording and no cup size involved.
Frequently asked questions
Why does the same cup of flour weigh differently each time?
Flour compacts in storage and packs further when scooped, so the amount that fits in a cup varies with the method. Spooning fluffed flour in and levelling it keeps the density consistent, which is why GramChef's 120 g per cup for all-purpose flour assumes that method.
Is spoon-and-level the same as sifting?
No. Spoon-and-level measures unsifted flour gently, while sifting is a separate step that aerates flour and lightens a cup. Wording gives the order away: 'sifted flour' as the ingredient name means sift before measuring.
How much flour is in a tablespoon?
For all-purpose flour, one tablespoon weighs 7.5 g and one teaspoon 2.5 g, based on 120 g per cup. Whole wheat flour is 7.1 g per tablespoon and almond flour is 6 g.
Can flour be measured in a liquid measuring jug?
Not accurately. A jug is awkward to level and flour settles unevenly in one, so the reading is unreliable. A dry measuring cup used with spoon-and-level, or a kitchen scale, gives a result that can be repeated.
