Flour is a pantry staple used in baking everything from breads and cakes to cookies and pies. With so many brands on the market, home bakers may wonder exactly how much flour is contained in a standard bag or package. King Arthur flour is a popular all-purpose flour known for its consistent quality and performance. But how many cups of flour come in a typical bag of King Arthur flour?
Standard Bag Sizes of King Arthur Flour
King Arthur flour comes in a few different standard sizes:
- 2 pound bag – approximately 8 cups of flour
- 5 pound bag – approximately 20 cups of flour
- 10 pound bag – approximately 40 cups of flour
- 25 pound bag – approximately 100 cups of flour
- 50 pound bag – approximately 200 cups of flour
The most common sizes home bakers will find are the 2 pound and 5 pound bags. Professional bakers and food service operations may purchase the larger 10 pound, 25 pound, or 50 pound bags.
Measuring Flour Accurately
When measuring flour, there are some important steps to ensure accuracy:
- Use measuring cups designed specifically for dry ingredients. Do not use liquid measuring cups.
- Spoon flour lightly into measuring cups and level off with a knife. Do not scoop measuring cups directly into the bag or tap the cup to settle flour.
- Use the “stir, scoop, and sweep” method: stir the flour in the bag or container first, then scoop and level off the measuring cup.
- Avoid compacting the flour into the cup. Loose, light flour will give you the most accurate measurement.
These steps help account for the air pockets within flour and provide the standard measurement that recipes are based on. Take care when measuring flour to achieve the intended texture and consistency when baking.
Weight Versus Volume
While package sizes are listed by volume (pounds), most professional recipes use weight measures for the most consistent and accurate results. Here are some weight equivalents for common King Arthur flour packages:
| Bag Size | Weight |
|---|---|
| 2 pound bag | 32 ounces / 907 grams |
| 5 pound bag | 80 ounces / 2,267 grams |
| 10 pound bag | 160 ounces / 4,535 grams |
| 25 pound bag | 400 ounces / 11,339 grams |
| 50 pound bag | 800 ounces / 22,679 grams |
Investing in a kitchen scale allows home bakers to achieve the most precise measurements for recipes. But when baking for family and friends where approximates are fine, knowing the standard cups per bag is a helpful reference.
Major Uses for All-Purpose Flour
As an all-purpose flour with 10-12% protein content, King Arthur flour works well in a wide variety of recipes, including:
- Breads – yeast breads, quick breads, muffins
- Cakes – layer cakes, sheet cakes, cupcakes
- Cookies – chocolate chip, sugar, peanut butter, oatmeal
- Pie Dough – fruit pies, pot pies, quiche
- Pasta – homemade egg noodles, ravioli
All-purpose flour provides sufficient structure to yield baked goods that are neither too dense and heavy nor too delicate and crumbly. The moderate protein content contributes to a balanced texture.
Tips for Storing Flour
To maximize freshness and shelf life of opened flour bags:
- Store flour in airtight containers or resealable plastic bags.
- Keep flour in a cool, dark place like a cupboard or pantry.
- Refrigeration can extend shelf life for a few months.
- Throw out flour if it smells funny, tastes bitter, or is infested with bugs.
- Discard all-purpose flour after 6-8 months past the printed expiration date.
- Whole wheat flour has more oils so store 3-6 months or freeze for longer periods.
Proper storage keeps flour fresher longer. Date opened bags with a marker to monitor shelf life. Buy only quantities that will be used within the freshness timeframe.
Cost Savings of Buying Large Bags
Home bakers who go through a lot of flour may benefit from purchasing 10, 25, or 50 pound bags. Here is a comparison of the cost difference between bag sizes at current King Arthur flour prices:

Frequently Asked Questions
Why does the weight vary slightly between bags of flour?
There can be slight variations in weight between bags due to differences in factors like moisture content and the density of milling. But generally the weight per bag size remains quite consistent.
Does sifting or scooping affect the amount of flour?
Yes, sifting removes a small amount of air pockets, resulting in a slightly denser measurement. Scooping directly into the flour bag compacts more flour into the cup compared to the spoon and level method.
Can I substitute other all-purpose flours in recipes calling for King Arthur?
You may need to adjust liquids slightly since protein content varies across brands. But generally you can substitute reputable all-purpose flours like Gold Medal or Pillsbury without issue.
How long does unopened flour last past the printed expiration date?
Unopened bags can last 6 months to 1 year beyond the expiration date if stored properly. Check for off odors and flavors before use. Whole wheat flour has a shorter shelf life than white due to oils.
Should I keep flour in the fridge or freezer?
Refrigerating or freezing flour in airtight containers can prolong freshness from a few months up to 1 year. Allow cold flour to come fully to room temperature before use.
