A standard packet of dry yeast usually contains about 2¼ teaspoons, which is 7 grams or ¼ ounce.

Quick Scoop

  • Most common supermarket packets of active dry or instant yeast: 7 g = 2¼ tsp = ¼ oz.
  • That amount is typically enough to raise dough made with around 3½–4 cups of flour, depending on the recipe and rise time.
  • Some fast-acting brands describe this as roughly ¾ of a tablespoon because 2¼ teaspoons is a bit less than a full tablespoon.

If you only have bulk yeast and your recipe calls for “1 packet,” just measure out 2¼ level teaspoons (7 g) and you will match a normal packet amount closely enough for most baking.
