How to Measure Flour Correctly

Published 9 February 2026

The way you measure flour can make or break a recipe. Scooping flour directly from the bag can add up to 30% more flour than intended — turning fluffy cakes into dense bricks and tender biscuits into tough pucks.

The Spoon & Level Method

This is the gold standard for measuring flour by volume. Here's how:

  1. Fluff the flour in the bag or canister with a spoon or fork. Flour compacts during storage, so loosening it first is essential.
  2. Spoon the flour into your measuring cup, letting it mound slightly. Don't shake or tap the cup — that compresses the flour.
  3. Level it off with a straight edge (a butter knife or the back of a knife works perfectly). Sweep across the top in one smooth motion.

Quick fact

1 cup of spooned-and-levelled plain flour = 125g. 1 cup of scooped plain flour = ~155g. That's a 24% difference!

Why Not Just Scoop?

When you plunge the measuring cup directly into the flour bag, you compress the flour against the sides and bottom of the cup. This packs in extra flour — sometimes up to 30 grams more per cup. Over 3 cups of flour in a recipe, that's an extra 90 grams (almost ¾ of a cup) of unintended flour.

The Best Method: Use a Scale

If you're serious about consistent results, invest in a digital kitchen scale. Weighing flour eliminates all the variability of cup measurements. Most professional bakers and recipe developers use weight measurements for exactly this reason.

Frequently Asked Questions

What is the spoon and level method?
The spoon and level method means using a spoon to scoop flour into your measuring cup (rather than dipping the cup into the bag), then levelling off the top with a straight edge like a knife. This prevents compressing the flour.
How much does 1 cup of flour weigh?
One US cup of plain (all-purpose) flour weighs approximately 125 grams or 4.4 ounces when spooned and levelled. Scooped flour can weigh up to 155 grams — a 24% difference.
Why does my flour measurement vary?
Flour measurement varies based on how you fill the cup: scooping compresses the flour (more grams), while spooning keeps it airy (fewer grams). Humidity, flour type and sifting also affect weight.
