How to Judge Serving Sizes

Ounces

  • A serving of meat, poultry, or fish is 2 to 3 ounces. This looks like the size of a deck of cards or the palm of the hand.

  • A serving of natural cheese is 1½ ounces. This looks like the size of 3 to 4 dice. A serving of processed cheese is 2 ounces.

Tablespoons and teaspoons
