How much fiber in an apple? About 4.4 g with the skin on
A medium apple with the skin contains roughly 4.4 g of fiber, around 17% of the daily target for women. Peeling it drops that to about 2.1 g, so the skin carries more than half the total.

Key takeaways
- A medium apple with skin carries about 4.4 g of fiber, a peeled one about 2.1 g.
- Roughly half the fiber sits in and just beneath the skin.
- Apple fiber is largely pectin, a soluble fiber with modest LDL-lowering evidence.
- Apple juice contains almost no fiber, the pulp and skin are removed in pressing.
A medium apple, eaten whole with the skin, contains roughly 4.4 g of fiber. That is a useful number to hold onto, because the same apple peeled contains about 2.1 g, and the difference is the single clearest illustration of where fruit fiber actually lives.
The numbers
| Form | Serving | Fiber |
|---|---|---|
| Apple, with skin | 1 medium (~180 g) | ~4.4 g |
| Apple, peeled | 1 medium | ~2.1 g |
| Apple, dried | 1/2 cup | ~3.5 g |
| Apple juice | 1 cup | ~0.5 g |
What kind of fiber it is
Most of an apple's soluble fiber is pectin, the same compound that sets jam. Pectin forms a gel in the gut, slows gastric emptying, and is among the soluble fibers with evidence for modestly lowering LDL cholesterol. The skin contributes the insoluble fraction, which is why removing it changes both the quantity and the mix.
Against the daily target
The target is 25 g a day for women and 38 g for men. One apple covers roughly 17% and 12% of those respectively. That is a real contribution and clearly not a plan. The common mental model of an apple as a fiber food slightly overstates the case.
Why juice does not count
Pressing separates the liquid from the pulp and skin, which is where nearly all the fiber is. What remains is the sugar and most of the potassium, without the viscosity that slows absorption. A glass of juice takes several apples to make and returns almost none of their fiber.
One caveat
The exact figure moves with variety and size. A small apple may sit near 3 g and a large one near 6 g. Treat 4.4 g as the working number for a medium fruit rather than a precise measurement of the one in your hand.
Frequently asked
How much fiber is in one apple?
A medium apple of roughly 180 g contains about 4.4 g of fiber when eaten with the skin. Larger apples scale up proportionally, so a big one can reach 5 to 6 g.
Should I eat the apple skin?
If you want the fiber, yes. Peeling removes more than half of it, along with most of the polyphenols. Washing handles surface residue, and peeling is not a meaningful pesticide strategy.
Is an apple a good source of fiber?
It is a solid contributor rather than a heavy hitter. At 4.4 g it covers roughly a sixth of the daily target for women. A cup of beans does four times as much in one serving.
