How much is a small/medium/large onion?

  • By size or weight - I never seem to know ...

  • Here's some general guidelines I have used in the past:

    Small onion = 4 ounces by weight or about ½ cup chopped

    Medium onion = 8 ounces, or about 1 cup chopped

    Large onion = 12 ounces, or about 1½ cups chopped

    Jumbo onion = 16 ounces, or about 2 cups chopped


    The terms are not always completely accurate so use your best judgement. I've often seen large onions that were as big or bigger than "jumbo" according to this data.
