The number of calories in an apple depends largely on its size, but here are the typical values:

• A medium-sized apple (about 3 inches in diameter or 182 grams) contains roughly 95 calories

• A small apple or 100 grams of apple provides about 52 calories

• A large apple may have around 110 calories or slightly more depending on exact weight

In summary, the most commonly cited calorie count for a medium apple is about 95 calories. Smaller apples have fewer calories, closer to 50-55, while larger apples can exceed 100 calories. This variation is due to size and variety differences.
