How many carbs are in French fries?
A small order of French fries, about 10 strips (65g), has roughly 20g of carbohydrate and 18g of net carbs. A full 9-oz bag delivers about 77g of carbs.
Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 10 strips (65g) | 19.6g | 1.9g | 17.7g |
| 100 grams | 30.1g | 2.9g | 27.2g |
Net carbs
Ten strips of French fries have about 18g of net carbs, which is total carbs (20g) minus fiber (about 2g). Potatoes do contain some fiber, but frying and skinless preparation keeps it low. Net carbs are the portion that raises blood glucose. See the net carbs guide for when net vs. total matters.
Glycemic index of French fries
The glycemic index of French fries is about 75. Fried potatoes have a high glycemic index because frying gelatinizes the starch and the lack of skin removes much of the fiber that would otherwise slow digestion. Cooling fries after cooking increases resistant starch slightly and nudges GI down, but the effect is modest.
For diabetes
French fries have both a high glycemic index and meaningful carb counts, so they raise blood sugar quickly relative to their volume. Ten strips carry about 20g of carbs, but restaurant medium and large orders are two to four times that. Portion size is the main lever here. Pairing fries with a protein source slows gastric emptying and softens the rise. Count total carbs for dosing. See the diabetes carb-counting guide.
Keto and low carb
Ten strips (65g) have about 18g of net carbs, nearly a full day's keto budget in a small side. A restaurant medium order can reach 40 to 50g of net carbs. French fries do not fit a standard keto plan. Swapping for a small salad or roasted non-starchy vegetables is the practical workaround.
Good to know
The USDA data here is for par-fried frozen fries before final cooking, so actual calories and fat will be slightly higher after oven-baking or deep-frying. Carbs are relatively stable across cooking methods because starch does not cook off, but fry size matters: thin shoestring fries pack more surface area and absorb more oil, but the carb count per gram of potato is nearly the same. A large fast-food serving often tops 70g of carbs before any sauces.

How many carbs are in French fries?
About 10 strips (65g) has roughly 20g of carbohydrate. A full 9-oz frozen package has about 77g of carbs before cooking.
How many net carbs are in French fries?
Ten strips have about 18g of net carbs. Potatoes have some fiber, but not enough to move the net carb count far from total carbs.
What is the glycemic index of French fries?
Fried potatoes have a glycemic index around 75, placing them in the high-GI category. Frying gelatinizes the starch and the skinless preparation removes fiber, both of which speed digestion.
Are French fries OK for diabetics?
They are high-GI and easy to overeat. A small 10-strip portion has about 20g of carbs, but restaurant orders are usually much larger. If you eat them, keep the portion small and pair with protein to slow the glucose rise.
Are French fries keto?
No. Ten strips have about 18g of net carbs, and a typical restaurant order has 40 to 50g. French fries do not fit a keto diet in any normal serving size.
Do sweet potato fries have fewer carbs than regular fries?
Sweet potato fries have a similar carb count per gram. The main difference is a slightly lower GI for sweet potatoes and more vitamin A, not a meaningfully lower carb load.
