How many calories are in grapes?
A 1 cup (151 g) has 104 calories. Per 100 grams, grapes has 69 calories. That cup has about 27 g of carbohydrate, nearly all sugar with under a gram of fiber, and very little protein or fat. Grapes are one of the higher-sugar fruits per 100 g, which is why they taste like candy.

The calories you might not be counting
Ten grapes are about 34 calories, and nobody eats ten grapes. The bag comes out of the fridge and the hand goes back five or six times while you stand at the counter. A typical untracked sitting is closer to two or three cups, which puts the total between 200 and 300 calories of nearly pure sugar. Frozen grapes, marketed as a healthy candy substitute, encourage the same volume. On a cheese board, grapes are background nibbling between the crackers and the brie, and nobody counts them. Wine is the other trap: a single glass starts at about 125 calories, and a glass poured at home tends to be larger than a 5-ounce standard. Forkd asks for the portion instead of accepting a vague "some grapes," so the real volume shows up.
Calories by size
USDA lists a cup of grapes at 151 g (about 104 calories) and 10 grapes at 49 g (about 34 calories). Most retail bags hold 450 to 680 g, so a bag is roughly 310 to 470 calories total. The difference between a handful (maybe 15 grapes, about 50 calories) and a bowl (two cups, about 208 calories) is easy to miss because grapes are small, sweet, and gone fast.
| Size | Weight | Calories |
|---|---|---|
| 10 grapes | 49 g | 34 |
| NLEA serving | 126 g | 87 |
| 1 cup | 151 g | 104 |
Scanning grapes with Forkd catches the exact portion and the hidden extras this page just described, the oil, the dressing, the topping a photo alone would miss.
Grapes calories: common questions
Are grapes good for weight loss?
Grapes are low in calories per grape but easy to eat in large quantities because they are bite-sized and sweet. A measured cup at 104 calories fits well. The risk is unmeasured handfuls that stack up without much fullness, since grapes have very little fiber.
How many calories are in 10 grapes?
Ten seedless grapes (about 49 g) have roughly 34 calories. A cup holds about 30 grapes and runs around 104 calories. Per 100 g, grapes are 69 calories.
Are grapes high in sugar?
A cup of grapes has about 23 g of sugar, most of it glucose and fructose. That is higher than most berries. The low fiber (under 1 g per cup) means there is little to slow absorption.
How many calories are in a bag of grapes?
A standard retail bag is about 1 to 1.5 pounds (450 to 680 g), which works out to roughly 310 to 470 calories for the whole bag.
