1 cup of all-purpose flour weighs 125 grams. Scooping flour directly from the bag compresses it and can add 30–50g extra per cup. Always spoon flour lightly into the measuring cup and level off the top with a straight edge — this is the most common source of error in baking.
For the most accurate results, weigh your flour with a digital kitchen scale — the values below assume a level, unpacked cup.

Practical baking & cooking tips for flour
- Always fluff flour with a fork or whisk before spooning it loosely into your cup.
- Never tap the cup on the counter or shake it, as this immediately settles and packs the grains.
- Sifting before measuring reduces weight per cup by 10–15g; only sift first if the recipe specifically specifies "1 cup sifted flour".
Common substitutions for flour
| Substitute | Ratio | Kitchen Notes |
|---|---|---|
| Self-raising flour | 1:1 by weight (125g per cup) | Omit 1 1/2 tsp baking powder and 1/4 tsp salt per cup |
| Almond flour | 1:1 by weight (requires extra binder) | Gluten-free; lacks gluten elasticity so add 1 extra egg or xanthan gum |
Why accuracy matters for flour
Flour is the primary structure-builder in baking. Because flour compresses easily, a scooped cup can weigh anywhere from 120g to 150g—a 25% difference. Excess flour leads to tough, dry, crumbly cakes and rubbery bread; too little causes cakes to sink in the centre.
Who needs grams for flour?
Essential for bakers converting US cup recipes to European metric measurements, ensuring exact gluten and hydration ratios.
Common mistakes to avoid with flour
- Scooping flour directly with a measuring cup, leading to too much flour.
- Not sifting flour when required, resulting in dense baked goods.
- Using the wrong type of flour (e.g., all-purpose instead of bread flour).
