Portion Sizes for Kids: How Much Food Is Healthy for My Child’s Age?

By: Jennifer Zarrilli, MS, RD

Some days, figuring out what to feed your child is hard enough. Figuring out how much can seem downright impossible. The recommended portions for a child depend on their age and even gender – and unfortunately, the serving size listed on grocery store labels doesn’t have much to do with it.

Connecticut Children’s is here to help. Here’s our guide to understanding healthy food portions for kids, including some time-saving tips.

Learn how to eyeball standard portions of common foods.

One of the reasons healthy portions seem so complicated? Different types of food are measured in different ways, from ounces to cups to teaspoons. Sure, you could rely on measuring cups and kitchen scales. But if you want a shortcut when it’s time to portion out food, you can also make rough measurements by imagining familiar items – or just using your hand.

The chart below is adapted from the Academy of Nutrition and Dietetics. Here are other handy visuals.

  • In general, 1 cup looks like a tennis ball.


  • In general, 1 cup looks like a baseball.


  • Lean beef or poultry: 3 ounces (oz.) looks like a deck of cards
  • Grilled or baked fish: 3 oz. looks like a checkbook
  • Peanut butter: 1 oz. looks like a ping-pong ball

1 ounce looks like:

  • Bread: DVD cover
  • Dry cereal: Baseball
  • Cooked cereal, rice or pasta: Half a baseball
  • Pancake or waffle: DVD
  • Bagel, hamburger bun: Hockey puck
  • Cornbread: Bar of soap

In general, 1 cup looks like a baseball.

Follow your child’s daily portion recommendations.

After a little practice with the above chart, you should find it easier to tell at a glance how much fruit is about a cup, how much sliced bread is an ounce, etc.

Now, here’s how much to serve your child each day, based on MyPlate.gov.
