But if you’re counting calories or simply curious about nutrition, you may wonder: how many calories in a Granny Smith apple? Understanding the nutritional profile of this fruit helps you make better choices for weight management, fitness, or overall health.
In this guide, we’ll break down the calories in a Granny Smith apple by size, with and without skin, and even by weight. You’ll also learn about the broader nutrition facts of this popular green apple. By the end, you’ll know exactly how Granny Smiths fit into your healthy lifestyle.

Granny Smith Apple Calories with Skin
Most people enjoy apples with their skin on, which adds fiber and nutrients. So, what are the Granny Smith apple calories with skin? A medium apple (about 200 grams) typically contains around 80 calories when eaten whole, skin included.
The skin provides valuable dietary fiber that supports digestion and helps you feel full longer. Leaving the peel on means you’re not just enjoying the crisp bite, you’re getting more nutrition for the same calorie count.
How Many Calories in a Granny Smith Apple Without Skin?
If you prefer peeling your apple before eating, you might be wondering: how many calories does that save? A medium Granny Smith apple without skin contains around 60–65 calories. The difference comes from the fiber-rich skin, which contributes both nutrients and calories.
While removing the skin lowers the calorie count slightly, it also reduces some of the health benefits. Without the skin, you lose a significant amount of fiber, vitamin C, and phytonutrients that support overall health. So while a peeled apple still makes a good snack, leaving the skin on gives you the most nutrition for every bite.
