A medium apple has about 95 calories. That’s roughly the size that fits comfortably in your hand, weighing around 180 to 200 grams. Smaller apples come in closer to 65 calories, while a large apple can reach 115 or more depending on the variety.
Calories by Apple Size
Apple calories scale predictably with size. A small apple (about 125 grams) has roughly 65 calories. A medium apple (around 180 grams) lands near 95 calories. A large apple (over 200 grams) can contain 110 to 120 calories. If you’re tracking closely, weighing your apple on a kitchen scale gives you the most accurate count, since “medium” is loosely defined.
How Variety Changes the Count
Not all apples are created equal when it comes to calories. The difference comes down to sugar content: sweeter varieties pack more energy per bite. Per 100 grams, here’s how the most popular types compare:
- Gala: 70 calories
- Granny Smith: 75 calories
- Fuji: 90 calories
- Honeycrisp: 95 calories
That means a large Honeycrisp can have close to 35% more calories than a same-sized Gala. In practical terms, the gap between the lowest and highest calorie varieties is about 50 calories for a full-sized apple. Not a huge difference in absolute terms, but worth knowing if you eat two or three a day.
What’s Inside Those Calories
Almost all of an apple’s calories come from sugar, roughly 20 to 25 grams in a larger apple. That sugar is a mix of three types: fructose makes up the largest share at about 6.5 grams per 100 grams of apple, followed by sucrose at around 4.75 grams, and glucose at about 1.5 grams. The rest of the apple’s carbohydrate is fiber.
A medium apple with the skin on contains about 3 grams of fiber, split between soluble and insoluble types. The skin alone accounts for roughly a third of that total fiber. Peeling your apple drops the fiber content to about 2 grams. Soluble fiber (including pectin, which apples are known for) slows digestion and helps moderate the blood sugar response, while insoluble fiber supports gut health.
Why Apples Don’t Spike Blood Sugar
Despite containing a fair amount of sugar, apples have a glycemic index of just 39, which is considered low. The glycemic load of a medium apple is only 6, well within the low range. For context, anything under 10 is low and unlikely to cause a meaningful blood sugar spike. The combination of fiber, water content, and the way fructose is processed by the body keeps the sugar release gradual.
Whole Apples vs. Apple Juice
A cup of apple juice has roughly the same calories as a whole apple, sometimes more, but it behaves very differently in your body. A trial with 64 adults at the University of Otago found that whole apples were significantly more satiating than apple juice, particularly in the first 30 minutes after eating. The fiber and physical structure of the fruit slow digestion and signal fullness in ways that juice simply can’t replicate.
This matters if you’re eating apples to manage hunger. A whole apple takes time to chew, fills your stomach with fiber and water, and keeps you satisfied longer. A glass of juice delivers the same sugar in seconds, with no fiber to slow it down. Calorie for calorie, the whole fruit is a much better deal.
Apples Compared to Other Fruit
At 95 calories for a medium serving, apples sit in the middle of the fruit calorie spectrum. A medium banana has about 105 calories. A cup of grapes runs around 100. A medium orange comes in near 65. A cup of watermelon is about 46. Apples stand out less for their calorie count and more for their portability, long shelf life, and high fiber-to-calorie ratio. Three grams of fiber for under 100 calories is a solid return, especially from something that doesn’t need refrigeration or preparation.
