Just How Much Does a Banana Weigh? Grams and Calories
A medium banana weighs about 118 grams of fruit and 105 calories, while a whole one with the peel runs closer to 150 grams. Here is every size in grams, plus calories, carbs, and how many bananas make a pound.

A medium banana holds about 118 grams of edible fruit and 105 calories, and the whole thing with its peel weighs closer to 150 grams. That gap between the fruit you eat and the fruit you buy is exactly why the question of how much does a banana weigh has more than one honest answer. Ripeness, variety, and size all nudge the number.
Grocery stores sell bananas loose by the pound, so the size in your hand can swing from a stubby 80 gram snack to a 150 gram monster. The average banana weight most nutrition charts use sits at 118 grams of flesh, based on USDA data. Below is every standard size, what it weighs, and what it costs you in calories.
How Much Does a Banana Weigh by Size
The USDA sorts bananas into five sizes by length, from extra small under 6 inches to extra large at 9 inches or more. Each size maps to a weight of edible fruit, which is what you get once the peel comes off. When someone asks how many grams in a banana, they usually mean the medium size, which runs 7 to 8 inches and about 118 grams.
| Size | Weight | Calories |
|---|---|---|
| Extra small | 81 g | 72 |
| Small | 101 g | 90 |
| Medium | 118 g | 105 |
| Large | 136 g | 121 |
| Extra large | 152 g | 135 |
Those gram figures are the flesh only, not the whole fruit. That matters if you weigh a banana on a kitchen scale with the peel still on, because the display will read higher than any nutrition label. If you would rather convert straight to ounces, our grams to ounces chart has every step.

Whole Banana vs Peeled, Where the Grams Go
Peel a banana and you lose real weight. The skin makes up somewhere between 20 and 35 percent of the whole fruit, depending on ripeness and type. Do the math on a pound of bananas and it lines up: three medium bananas weigh about 454 grams whole, while their combined flesh is closer to 354 grams.
A medium banana is about 118 grams of edible fruit and 105 calories, and the peel adds another 30 grams or so on top of that.
For calorie tracking, log the peeled weight or the standard 118 grams, never the number your scale shows with the skin on. If you want to convert that flesh weight into other units, a quick grams to ounces converter turns 118 grams into about 4.2 ounces in one tap.
How Many Calories in a Banana
Bananas carry 89 calories per 100 grams of fruit, so calories track almost perfectly with weight. That puts a medium banana at 105 calories, a small one at 90, and an extra large at 135. The banana calories you actually eat depend far more on the size you grab than on how ripe it is.

Compared with other quick snacks, a banana lands in friendly territory. Its banana calorie content is close to a small apple and well under a granola bar, while it delivers potassium and fiber that most packaged snacks skip. For portion tracking, our chicken breast portion guide uses the same weigh then log approach.
Banana Nutrition Facts Beyond Calories
Calories are only part of the story. A medium 118 gram banana packs about 27 grams of carbohydrate, 3.1 grams of fiber, 14 grams of natural sugar, and 422 mg of potassium, according to USDA figures. The full nutritional information for a banana also lists 1.3 grams of protein and just 0.4 grams of fat. If you have ever asked how many carbs in a banana, that 27 gram count is your answer for a medium fruit.

How Many Bananas in a Pound, Cup, and Bunch
Buying by weight? One pound of bananas is about three medium fruits, or 454 grams. For baking, a cup of sliced banana weighs roughly 150 grams, and a cup of mashed banana is about 225 grams, which works out to two medium bananas, per kitchen conversion charts.
| Measure | Amount | Grams |
|---|---|---|
| 1 medium banana | peeled fruit | 118 g |
| 1 pound | 3 medium | 454 g |
| 1 cup sliced | about 1 banana | 150 g |
| 1 cup mashed | 2 medium | 225 g |
Three medium bananas weigh about a pound, so a bunch of six is close to two pounds before you peel a single one.

What a Banana's Weight Means for Your Day
Here is where grams turn into outcomes. If you count calories, logging a banana as 105 instead of eyeballing it can be the difference between hitting a target and drifting 50 calories over a few times a day. Bakers feel it too, since a recipe built on 225 grams of mashed banana turns out differently when you use three fat bananas instead of two.
Baking and smoothies by the gram
Smoothie and protein shake recipes lean on banana for sweetness and body, and swapping a small banana for an extra large one adds close to 60 grams of fruit and 45 calories. Weighing the peeled fruit keeps your macros honest. A grams to pounds converter helps when a recipe jumps between metric and imperial.
If a recipe calls for 225 grams of mashed banana, reach for two medium fruits, not three, or the loaf turns out wetter and sweeter than intended.
