How to Approximate a Teaspoon

Whether you’re baking a pie, making a pot of soup or preparing a marinade for a steak, at some point, you’ll probably need measuring cups and measuring spoons to accurately follow your recipe. However, if you don’t have a dedicated set of measuring utensils, do you have to abandon your dish altogether? Or, can you use one of the many ways to approximate measurements to complete your recipe?

A number of benefits exist in knowing how to quickly and accurately estimate a teaspoon:

1. If you’re camping, renting a poorly equipped vacation accommodation, or cooking at a friend’s house, knowing how to estimate a teaspoon will come in handy.
2. Being able to accurately approximate teaspoons and other measurements saves time – no more digging through drawers.
3. Finally, approximating saves on kitchen clutter and dishes. If you don’t use a teaspoon, you don’t have to wash a teaspoon.

While a smidgen too much sage won’t ruin your stew, not enough baking powder or a tiny bit too much salt can quickly spell disaster in your bread recipe.

The point? Don’t estimate a teaspoon while baking unless you’re very confident in your skills or if you don’t have any other choice.

One teaspoon of sugar equals about 4 grams, while a heaping teaspoon is about 7.5 grams, or 0.17 ounces. So, if you have a kitchen scale on-hand that’s pretty accurate, you can measure your dry ingredients on it.

One teaspoon of water is about 5 ml or, again, 0.17 ounces, but most people don't have the equipment lying around to measure such a small amount of liquid. If you’re trying to estimate a teaspoon of liquid, such as vanilla, consider just adding a capful.

If you don’t have a teaspoon, the single easiest way to approximate one is to use a regular spoon – the kind you’d eat cereal with – and fill it about halfway. While these spoons aren’t uniform in size, you should be familiar with what a standard kitchen spoon looks like, so if it’s bigger or smaller than that, adjust the measurement accordingly.

Another easy method if you have a tablespoon on hand, but not a teaspoon: Since 3 teaspoons equals 1 tablespoon, fill a tablespoon 1/3 of the way to get a close measurement.

Did you know that one three-fingered pinch is roughly equal to 1/8 teaspoon? It’s true. Just use your thumb, index finger and middle finger to pinch a bit of ground spice and throw it in the bowl. Repeat eight times, and you’ve put approximately 1 teaspoon into your mixture.

While it’s not the most accurate way of measuring a teaspoon, using your palm to approximate your measurement works for most non-baking dishes with no issues, especially if you’re just adding flavor to a dish. It’s perfectly safe to “eyeball it.”

1. 1/4 teaspoon is a mound the size of a dime.
2. 1/2 teaspoon is a mound the size of a nickel.
3. 1 teaspoon is a mound a little larger than a quarter.

Another quick eyeballing method? A teaspoon is about the length of the tip of your index finger or 1 inch.

Estimating teaspoons and other measurements is something that you can practice and get better doing. When you have a few moments, get out some flour or sugar (or whatever granular ingredient you have on hand) as well as a set of measuring spoons.

One by one, pour a measuring spoonful of the flour into your palm to get the look and feel for how much it is; then move on to the next spoon. Soon, you’ll have a much better idea of what differing amounts of flour look like in your hand.
