One serving of fruit is 1 cup of fresh fruit, about the size of a baseball. That’s the standard used by the USDA’s MyPlate guidelines, and it applies to most chopped, sliced, or whole fresh fruits. But the actual amount varies depending on the type of fruit and how it’s prepared, so a “serving” of dried raisins looks very different from a serving of watermelon.
What Counts as One Cup
For most fresh fruits, one serving equals 1 cup of chopped or sliced pieces. If you’re eating whole fruits, the equivalent looks like this:
- Banana: 1 large banana
- Orange: 1 large orange
- Apple: 1 large apple (about 242 g)
- Grapes: 32 seedless grapes
- Strawberries: 8 medium strawberries
- Kiwi: 2 medium kiwifruits
- Plums: 2 medium plums
- Peach or nectarine: 1 medium fruit
- Pear: 1 medium pear
- Grapefruit: 1/2 medium grapefruit
For berries like blueberries, raspberries, or blackberries, one serving is simply 1 cup of whole berries, fresh or frozen.
Large Fruits Like Melon and Pineapple
With big fruits, it helps to think in terms of cups rather than slices, since slice thickness varies. One cup of diced watermelon, cantaloupe, or pineapple counts as a full serving. For context, a quarter of a medium cantaloupe (about 134 g) comes to roughly one serving, and two slices of pineapple (about 112 g) gets you to one serving as well. Two cups of diced watermelon is listed by the FDA as a single portion at 80 calories, so watermelon is one of the lowest-calorie options per volume.
Dried Fruit Is Measured Differently
Dried fruit is much more concentrated than fresh, so the serving size is smaller. Just 1/2 cup of dried fruit counts as the equivalent of 1 full cup of fresh fruit under USDA guidelines. Australian dietary guidelines put it even more precisely at 30 grams, which is about 4 dried apricot halves or 1.5 tablespoons of raisins.
The reason for the smaller portion is simple: when water is removed, the sugars and calories pack into a much smaller volume. A half cup of raisins has roughly the same calories and sugar as a full cup of fresh grapes, but it’s far easier to eat quickly without feeling full.
Juice Serving Sizes
One cup (8 fluid ounces) of 100% fruit juice counts as one serving of fruit. For adults and older kids, 8 to 12 ounces per day is a reasonable limit. Juice lacks the fiber of whole fruit and is easier to overconsume, so most nutrition guidance treats it as a secondary option rather than a replacement for eating fruit.
Frozen and Canned Fruit
Frozen and canned fruits follow the same cup-for-cup measurements as fresh. A quarter cup of thawed frozen peaches counts as a quarter-cup serving, and a cup of canned fruit cocktail counts as one full serving. The key difference is what’s packed around the fruit. Canned fruit in water or its own juice keeps the calorie count close to fresh, while fruit packed in heavy syrup can add significant sugar. If you’re buying canned, look for “packed in water” or “packed in 100% juice” on the label.
Calories and Sugar by Fruit
Not all servings are nutritionally equal. A serving of strawberries has about 50 calories and 8 grams of sugar, while a large apple comes in at 130 calories and 25 grams of sugar. Here’s how some popular fruits compare per serving:
- Strawberries (8 medium): 50 calories, 8 g sugar, 2 g fiber
- Cantaloupe (1/4 medium): 50 calories, 11 g sugar, 1 g fiber
- Peach (1 medium): 60 calories, 13 g sugar, 2 g fiber
- Orange (1 medium): 80 calories, 14 g sugar, 3 g fiber
- Banana (1 medium): 110 calories, 19 g sugar, 3 g fiber
- Apple (1 large): 130 calories, 25 g sugar, 5 g fiber
- Pear (1 medium): 100 calories, 16 g sugar, 6 g fiber
- Grapes (3/4 cup): 90 calories, 20 g sugar, 1 g fiber
- Cherries (1 cup): 100 calories, 16 g sugar, 1 g fiber
If you’re watching sugar intake, berries, melons, and stone fruits (peaches, plums, nectarines) tend to be the lowest-sugar choices. If you want fiber, pears and apples are standouts at 5 to 6 grams per serving.
How Many Servings You Need Per Day
The recommended daily intake for adults is 2 cups of fruit, based on a 2,000-calorie diet. That’s two servings. Most people don’t hit that target. Spreading it across the day is easier than it sounds: a banana at breakfast and a cup of berries as a snack gets you there. Mixing forms (fresh, frozen, dried) all count toward the same goal, so frozen blueberries in a smoothie are just as valid as a fresh orange.
