How to Measure Flour

One of the most important cooking tips for making wonderful baked goods is knowing how to measure flour.

Even the best cooks will make mistakes from time to time. One of the most common mistakes that new bakers make is not measuring flour correctly.

If you take a measuring cup and scoop the flour out of the bag or canister, you are making the same mistake that many make.

Here is the USA, most cooks use measuring cups to measure flour, but the most accurate way to measure flour is to weigh it.

However, not all flours are equal, so no one weight is accurate for all of them. Read on to learn more about weighing flour.

Knowing how to measure flour is an important part of baking. Scooping it out of a canister and into a mixing bowl is a common mistake that beginners make. Find out how to measure flour correctly in my article.

There are two ways to measure flour – in a measuring cup and on a kitchen scale.

Most cups of the different flours weigh in at around 4 – 4 1/2 ounces or 112-126 grams or so (one ounce is 28 grams.)

Here are a few measurements for flour that is commonly used to bake. (This can depend on the brand of flour but is a pretty good overall guide.)Weighing is a very accurate way of measuring flour.

  • 1 cup of all purpose flour, bread flour and whole wheat flour weigh approximately 4 1/2 ounces (126 grams) each
  • 1 cup cake flour and pastry flour weigh about 4 ounces (112 grams) each.

I say approximately, and about in the weights above, because the results can vary depending on how the flour is scooped out of the container.  King Arthur Flour has a handy list of measurements for flour weights that covers just about any kind of flour you can think of.

If a digital kitchen scale is not something that you have in your kitchen tools, then a measuring cup is probably how you measure flour.

Reaching into the canister and scooping out a cup of flour does one thing very well. It PACKS the flour nicely.  But packed flour is not exactly what we are going for in light baked goods, now is it?

There could be a few ounces of difference in a scooped cup of flour and a weighed 126 grams of flour. That means that you are adding MORE flour than the recipe is calling for.

And that extra flour?  It will make for a heavy cake, dry cookies, crumbly pies crusts, and thick sauces.

The solution to this problem is to spoon the flour into the measuring cup instead of scooping it.

Using a spoon lightens the flour so that it doesn’t pack down in the measuring cup. Just spoon until the cup is overflowing with flour.

Don't scoop. Spoon the flour into the measuring cup.

Then you take a flat edge – a knife or spatula will do just fine as long as it has a flat edge and is long enough to fit across the top of the cup – and draw it evenly across the cup to remove the excess flour.

That’s all there is to it!


Knowing how to measure flour is the key to turning out light and beautiful baked goods. So promise me – no more scooping!

If you have a kitchen scale, you can test this.  Scoop out one cup of flour and weigh it. Then spoon out a cup, level it and weigh it. See the difference? I bet it is at least 50 grams or almost 2 ounces!!
