How Many Calories Are in an Apple? (The Accurate Answer by Size)

“An apple a day keeps the doctor away,” but does it keep the extra weight away too? If you are tracking your intake, the first question you’ll ask is: How many calories are in an apple?

It’s one of the most Googled nutrition questions for a reason. Apples are the ultimate portable snack, but their calorie count isn’t a single, fixed number. It depends entirely on how big the apple is.

Here is the definitive, data-driven guide to what’s inside your favorite fruit.

The Simple Answer: A “Medium” Apple

For most people grabbing an apple from the grocery store, here is the standard answer:

A medium-sized apple (about 182 grams and 3 inches in diameter) has approximately 95 calories.

That’s it. For under 100 calories, you get a filling snack that’s packed with fiber and water, which helps curb your appetite.

✨ The Calorie Breakdown by Size

The number one factor affecting calorie count is size. A tiny lunchbox apple is very different from a giant Honeycrisp.

Here is a glowing guide to help you estimate what you are eating:

Does the Type of Apple Matter?

Not really. Whether you choose a sweet Gala, a tart Granny Smith, or a crisp Fuji, the calorie difference per 100 grams is tiny—usually only 2-3 calories.

• Sweeter apples (like Fuji) might have slightly more natural sugar.
• Tarter apples (like Granny Smith) might have slightly less.

But for practical purposes, size is the only thing you need to watch.

Why These Are “Good” Calories

Unlike 100 calories of soda or candy, the 95 calories in an apple come with major benefits:

• High in Fiber: About 4 grams, which helps digestion and makes you feel full.
• High Water Content: Apples are about 86% water, which is great for hydration.
• Rich in Nutrients: You get a good dose of Vitamin C, potassium, and antioxidants.

So, the next time you ask how many calories are in that apple, know that it’s a smart, low-calorie choice that your body will thank you for.
