Why the Weight of Cake Flour Varies in Baking
Cake Flour contains fine milled grain particles that settle and compact significantly during transit and storage. Ambient humidity also causes dry flour to absorb airborne moisture, increasing its weight without expanding volume. Spooning vs. direct cup scooping creates the largest real-world weight difference.
Flours & Grains Measuring Technique
Cake flour is finely milled and packs easily. Always sift before measuring or weigh to 114g for delicate, airy crumb.
Atmospheric Altitude Context
At 5280 ft elevation, lower atmospheric pressure accelerates moisture evaporation. Ensure Cake Flour is measured strictly by weight (114g/cup) rather than volume scoop to prevent baking inconsistencies.
International Cup Size Weights for Cake Flour
Standard cup volumes vary between countries. If following a UK, Australian, or Canadian recipe, use these computed gram equivalents for Cake Flour:
| Standard Cup Standard | Volume (mL) | Calculated Grams (g) | Ounces (oz) | Primary Geographic Region |
|---|---|---|---|---|
| US Legal Cup (USDA Standard) | 240 mL | 114 g | 4.02 oz | United States (FDA nutrition labeling) |
| US Customary Cup | 236.6 mL | 112.4 g | 3.96 oz | United States (Standard kitchen measuring sets) |
| Metric Cup | 250 mL | 118.8 g | 4.19 oz | Australia, New Zealand, Canada, South Africa, UK |
| Imperial Cup | 284.1 mL | 135 g | 4.76 oz | Traditional British & Commonwealth recipes (1/2 pint) |

Frequently Asked Questions About Cake Flour
Why does a cup of Cake Flour weigh different amounts?
Cake Flour settles and packs tightly in the bag during shipping. Scooping directly with a measuring cup compresses the particles, cramming up to 140–150 grams into the cup. In contrast, fluffing with a fork and spooning gently into the cup yields the standard benchmark of approximately 114 grams. Weighing with a digital kitchen scale eliminates this volume variation entirely.
Should I sift Cake Flour before or after measuring?
Pay close attention to the recipe phrasing: "1 cup Cake Flour, sifted" means measure 1 cup first, then sift it into your mixing bowl. "1 cup sifted Cake Flour" means sift the flour into a mound first, then gently spoon 1 cup from that aerated mound. When measuring by weight on a gram scale, sifting timing has zero effect on the total flour mass.
How many grams of Cake Flour are in one tablespoon?
One level US tablespoon of Cake Flour weighs approximately 7.13 grams, and one level teaspoon weighs 2.38 grams. There are 16 tablespoons in 1 standard US cup (114g).
Can I swap Cake Flour 1:1 by volume with all-purpose flour?
No. Different flours vary widely in protein content, fiber absorption, and bulk density. Substituting by volume (cups) alters batter hydration and gluten development. Always substitute alternative flours by weight in grams rather than volume, and monitor whether your dough requires additional liquid.
How does altitude affect measuring Cake Flour?
At higher elevations (3,000+ ft), dry atmospheric pressure accelerates moisture evaporation from dry pantry goods, making Cake Flour drier and prone to packing denser per scoop. Weighing strictly to 114 grams per cup prevents adding excessive dry solids to your batter.

USDA SR Legacy specifies 114g for 1 cup sifted cake flour (4 oz = 113.5g). Unchecked scooping can compact cake flour up to 137g.
