Why Bake by Weight? The Case for a Kitchen Scale

Weighing ingredients makes baking more consistent, cuts down on washing up and makes scaling recipes simple. Here is how it works in practice.

Professional bakers almost never measure in cups. They weigh everything, and most recipes outside the United States are written in grams. Once you try it at home, it is hard to go back. Here is why.

1. The same recipe turns out the same way

A cup is a measure of space, not of how much ingredient is in it. Flour, brown sugar, cocoa and anything else that can be packed or fluffed will give you a different amount depending on how you fill the cup. As our flour measuring guide explains, a cup of flour can vary by a quarter or more between bakers. A gram is a gram: 120 g of flour is the same in every kitchen.

That consistency is what makes a recipe repeatable. If a bake turns out well, you can make it again exactly. If it turns out badly, you know the measurements were not the problem and can look elsewhere.

2. Fewer dishes

With cups, every ingredient needs a cup or spoon, and sticky ones like honey and peanut butter need scraping out. With a scale, you set the mixing bowl on top, press tare, add the first ingredient, press tare again and add the next. Most doughs and batters can be made in one bowl without a single measuring cup.

3. Scaling recipes becomes simple

Halving a recipe that calls for 3/4 cup plus 2 tablespoons of sugar means working out what half of that is. Halving 175 g is 87.5 g. Weights make it easy to double, halve or adjust a recipe to fit a different pan.

4. Recipes from anywhere become usable

Most recipes from Europe, Australia and Asia are written in grams, and cup sizes differ between countries anyway (see cup sizes around the world). With a scale, a recipe from anywhere works in your kitchen.

5. Small amounts are more accurate

Leaveners and salt matter a lot in small quantities. Measuring spoons are easy to heap or under-fill, and different salts weigh very different amounts per spoon. A scale that reads to 1 g, or a small jewelry-style scale that reads to 0.1 g, takes the guesswork out.

Is it ever fine to use cups?

Yes. Water, milk and other thin liquids measure accurately by volume, and many everyday recipes are forgiving. Cups are also fine for things that do not need precision, like a handful of chopped nuts for a salad. Weighing matters most for baking, where the ratio of flour, fat, sugar and liquid determines the result.

How to start

  1. Get a basic digital kitchen scale. Our kitchen scale guide covers what to look for.
  2. Convert your favorite recipe once using the charts on this site, and write the grams in the margin.
  3. Bake it a few times by weight. You will notice the difference in consistency quickly.
