Kiwi is a small, vitamin C-rich fruit that also delivers a respectable amount of dietary fiber. A 100-gram portion of green kiwi provides about 3 grams of fiber, while the popular golden/sungold variety provides around 1.9 grams. Because serving sizes vary—a whole kiwi, a sliced cup, or a handful of chunks—it can be awkward to estimate your fiber intake on the fly.
This calculator converts your serving size into a precise fiber figure using per-100g values. It is useful for anyone tracking daily fiber, planning balanced meals, following a gut-health routine, building high-fiber snacks, or simply comparing portion sizes. Enter your amount, choose your kiwi variety, and the tool returns the fiber in grams, the serving weight, and the percentage of the daily reference value.
🥝 Kiwi Fiber Quick Calculator
Estimate dietary fiber in kiwifruit from your serving size, variety, and portion unit.
How to Use This Tool
The calculator is built around fiber-per-100g values, so you can start with any amount that matches what is on your plate. Here’s the quick workflow:
- Type the quantity into the amount field. If you are using a food scale, enter weighed grams; if you are estimating, choose whole medium kiwi or cup sliced from the unit dropdown.
- Select your kiwi variety. Green kiwi is the classic fuzzy Hayward type sold in most supermarkets; gold/sungold kiwi has smoother skin, yellower flesh, and a lower fiber content.
- Press Calculate Fiber and read your result. The total is shown in grams and as a percentage of the 28-gram daily reference value used on U.S. Nutrition Facts labels.
Use the preset shortcut buttons when your portion matches a common size, such as one medium kiwi or one cup of sliced fruit.
Formula Explained
The math is simple once the serving size is converted to grams:
Fiber (g) = serving amount × grams per unit × (fiber per 100 g ÷ 100)
Grams per unit conversions used here: 1 medium kiwi ≈ 69 g of edible flesh, 1 cup of sliced kiwi ≈ 180 g, and 1 ounce = 28.35 g. If your portion is already weighed in grams, the grams-per-unit factor is simply 1.
After total fiber is calculated, the tool expresses it as a percent of the Daily Value:
% Daily Value = fiber (g) ÷ 28 g × 100
Worked Examples
Example 1 — 100 g green kiwi: 100 g × 3.0 g/100 g = 3.0 g fiber. This provides about 10.7% DV.
Example 2 — one medium green kiwi: 69 g × 3.0 ÷ 100 = about 2.1 g fiber, or roughly 7.4% DV.
Example 3 — one cup of sliced green kiwi: 180 g × 3.0 ÷ 100 = 5.4 g fiber, or about 19.3% DV — a meaningful chunk of a daily 25–38 g goal.
Reference Data: Fiber in Kiwi Portions
The table below shows approximate fiber values used by this calculator. Green kiwi is the default; gold/sungold kiwi is lower in fiber. Values are rounded and based on the edible flesh of raw fruit.
| Portion | Approx. weight | Fiber (green) | Fiber (gold) |
|---|---|---|---|
| 100 g | 100 g | 3.0 g | 1.9 g |
| 1 medium kiwi | 69 g | 2.1 g | 1.3 g |
| 1 cup sliced | 180 g | 5.4 g | 3.4 g |
| 1 oz | 28.35 g | 0.9 g | 0.5 g |
Tips for Getting More Fiber from Kiwi
- Weigh the fruit whenever accuracy matters. Using grams avoids the natural variation in cup measurements caused by different slice thickness and packing.
- Keep the skin on if you can tolerate the texture. The fuzzy brown skin is edible and contributes extra fiber, though the calculator estimates peeled flesh values, so your actual intake will be a little higher when the skin is eaten.
- Pair kiwi with yogurt, oats, granola, or a handful of nuts to build a balanced snack that combines fiber, protein, and healthy fats.
- Use fiber values when calculating net carbs: total carbohydrates minus fiber gives the digestible carbohydrate estimate. For a comparison of another fiber-rich breakfast ingredient, the oat fiber calculator is a handy reference.
Frequently Asked Questions
Which kiwi has more fiber, green or gold?
Green kiwi is the better source. The green Hayward variety usually contains about 3.0 g of fiber per 100 g, while gold/sungold varieties are closer to 1.9 g per 100 g. Both are valid fruit choices; green simply gives you more fiber for the same weight.
Does eating the skin change the fiber count?
Yes, in your favor. The skin adds extra insoluble fiber, so an unpeeled kiwi provides more total fiber than the peeled-flesh estimates shown here. Wash the fruit thoroughly first if you plan to eat it skin-on.
Where do the fiber numbers come from?
The green kiwi value is consistent with the USDA FoodData Central nutrient profile for raw kiwifruit. Gold kiwi averages are based on published variety comparisons and can differ by brand and season. For the most accurate personal data, weigh your kiwi and use the gram input.
