A medium-sized banana (about 7 to 8 inches long, 118 grams) typically contains around 27 grams of total carbohydrates. This includes about 3 grams of fiber and roughly 14 grams of natural sugars. The net carbs (total carbs minus fiber) are approximately 24 grams. The carbohydrate content can vary depending on the size and ripeness of the banana, with smaller bananas containing fewer carbs (around 19 grams for extra small) and larger bananas containing more (up to 35 grams for extra large)
