Bob's Red Mill Flour Weight Chart

By: Whitney Barnes | June 19 2019

For best results in baking, we recommend that you weigh the ingredients with a digital scale. With a plethora of different flour varieties out there, we’ve created a flour weight chart for easy reference in baking.

What is the weight of 1 cup of flour?

Well I'm so glad you asked! Our most popular flour, Organic Unbleached White All Purpose Flour, weighs 136 grams per 1 cup. All of our flours have a slightly different weight per cup because of their varying density and particle size. The amount of flour that fits into 1 cup depends largely on how big the particles are. If it's a coarser grind, like our Hazelnut Flour, less flour fits in a cup and therefore weighs less per cup - only 112 grams. If it's a super fine grind, like Sweet White Rice Flour, more flour fits into a cup and will weigh more - 204 grams! Baking is a science and the seemingly insignificant differences can result in big changes in the final product. As more and more home cooks bake by weight versus volume, having a handy flour weight chart will be a indispensable tool. In our newer recipes, we've started to include volume and weight measurements for all ingredients.

How do you measure flour?

The correct way to measure out flour is to spoon it into a measuring cup then use the flat side of a knife or other straight edged utensil to level the flour across the cup, sweeping the excess back into the flour bin. Do not pack the flour into the cup or scoop directly from the bag as both methods can lead to incorrect measurements. If using a scale, place a bowl on the scale, tare the scale, then spoon flour into the bowl until you reach the desired weight.

Hi.If plain white flour is 120g per cup but the 1-1 gf baing flour is 148g per cup,do I bake by weights or cups? And then !-1 baking flour isn't really a cup for cup replacement because of the weight difference?

  Hi Renee - Yes, our Gluten Free 1-to-1 Baking Flour (148 grams per 1 cup) is heavier by weight because the blend of flours have different densities in comparison to Organic All Purpose Unbleached White Flour (136 grams per 1 cup). If baking by volume, it is a 1:1 or cup for cup replacement - no additional changes necessary. If baking by weight and converting a wheat recipe into a gluten free recipe, just keep in mind that a cup of our Gluten Free 1-to-1 Baking Flour is heavier than Organic All Purpose Unbleached White Flour by 12 grams and increase your measurement accordingly.

I bought a case of your Unbleached Superfine Cake Flour. How many grams of that, unsifted, is in a cup? By unsifted, I mean poured from the bag into the scale. Thanks!

  1 cup of our Superfine Cake Flour would be 136 grams.

  Thanks for the reply, Whitney. 136g is what the bag says, 1/4 cup = 34g x 4 = 136. I did a few tests, pouring unsifted cake flour into a cup, leveling it, then weighing it and every time it was 130g. That is why I posted here, actually. A competitor’s brand of cake flour, available at most every store in a box, says 1 cup of their unsifted cake flour is 130g. I bought a case of Bob’s cake flour because I thought it would be better, and more efficient than 1 box at a time. I’m going to use 130g per cup of your cake flour a couple more times and see how things turn out.

Hello! Why is your Unbleached White AP Flour 136 grams in a cup, but King Arthur says 120? It's really hard to convert a receipt to weight when I'm using bulk flour and I can't find sources that agree on how many grams there are in a cup of unbleached all purpose flour. Can you help?

  Hi Becca, we base our weights on our products specifically. A great discrepancy in flour weight can also be a result of measuring technique. We recommend aerating your flour (a light whisking) then spooning the flour into the measuring cup and sweeping away the excess.

my husband has been diagnosed with celiac disease so I'm starting to bake gluten free but I'm getting conflicting information i want to know how much gluten free flour weighs one site states that all gluten free flour weighs 140 gram per 1 cup of gluten free flour another site states different weighs for different types of gluten free flour. help please

  Hi Valerie, you can refer to this post to see how many grams are in a cup of each flour. As you can see in the chart, each flour has a slightly different weight. This is because they are milled from different grains, each with varying density.

Hi, does ¼ cup equal to 4 tablespoons. I need to use 1 tablespoon of vital wheat gluten in my recipe. Would that be 7.5 gm since ¼ cup of vital wheat gluten here equals 30gm

  Hi! Yes, 1/4 cup is equivalent to 4 tablespoons when measuring by volume.
  
  1 tbsp of Vital Wheat Gluten weighs 7.5 grams and 1/4 cup (4 tbsp) weighs 30 grams.

  Hi Richard, you can always look at the nutritional panel to find the weight (in grams) of a cup. Typically the serving size is 1/4 cup, but can vary depending on the flour. Just multiply the gram weight of a serving by the appropriate amount to get the 1 cup equivalent. Happy baking!

I am using 1:1 flour to make a loaf of no knead bread. The chart indicates that I need 444 grams of flour for the 3 cups required in the recipe. This makes for an extremely dry mixture - no "wet dough" is created. Do I need to adjust anything? It's barely malleable and does not form a ball. Please advise. Thank you.

  Hi Bea - gluten free flour behaves differently than wheat flour. It sounds like the gluten free flour has absorbed all the liquid and you will likely need to add more.
  
  We have a great recipe for gluten free no knead bread using our Gluten Free All Purpose Flour. Here's a link!

I'm measuring one cup of oat flour at 93 grams with one measuring cup, and 90 grams with a different measuring cup. Your chart indicates that the weight should be 120 grams. I followed the instructions to spoon the flour into the measuring cup and level with a straight edge. Can you help me understand what I'm doing wrong? Thanks!

Commenting on the person who was getting different weights with different measuring cups. I watched an evaluation of measuring cups on a television show. Sadly not all cups are accurate. If you have an accurate weight for the product you are using, work with the weight.

  Hi Connie - I'd recommend replacing it by volume; use 1 1/2 cups of Brown Rice Flour.

  Hi Denise - both of those are lower protein flours; they would work best in pancakes or quick breads. Enjoy!

Speaking to "how much does one cup of flour weigh?" The simple answer is that it gets complicated. There are many articles dedicated to this question. After calling King Arthur Flour, and reading a number of articles concerning this question (google it), I believe the answer is "depends on who you ask". Everyone seems to use similar technique to answer this question, but it is an experiment to arrive at a close approximation. The final answer is to use the value given in the recipe. It apparently worked for the recipe writer.

I couldn't find the weights for gluten-free pie crust on your list. There were so many kinds of flour that maybe I missed it, but it would be very helpful to me if you could send it.
Thank you, Karen

Do stone ground wheat flour and regular whole wheat flour weigh the same? I’m using your stone ground whole wheat flour for a bread recipe and it would seem the weight would be different because of the texture but it is the same in your chart??
