A traditional matcha spoon does not have one exact measurement, but a heaped bamboo scoop usually holds around 1 gram of matcha.
The traditional bamboo matcha scoop is called a chashaku. It is meant to portion matcha rather than work like a 1g matcha spoon, so the amount can vary from scoop to scoop.
How Many Grams Does a Matcha Spoon Hold?
That number is not exact.
Different chashaku shapes, the size of the heap and how the powder settles can all change the amount. Even Japanese tea makers use slightly different scoop counts when describing servings of roughly 1.5 to 2 grams.
Why Is a Chashaku Not an Exact Measurement?
A traditional chashaku is a shallow bamboo scoop rather than a standardized measuring utensil. Two scoops that look similar can still contain slightly different amounts of matcha.
This is part of why matcha recipes are more consistent when they give the amount in grams instead of only saying how many scoops to use.

What About a 1 Gram Matcha Spoon?
Some modern matcha spoons are calibrated to measure a specific amount. A spoon designed to measure 1 gram gives you a much more repeatable portion.
This can be useful when you want the same strength each morning without weighing the powder on a scale.
A Simple Way to Measure Matcha
One heaped chashaku is roughly 1 gram, but it is not an exact standard. Use a traditional scoop when a little variation is fine, and use a scale or 1g measuring spoon when you want the same amount every time.
