Couscous is a versatile semolina-based grain that serves as a staple side dish across North African and Middle Eastern cooking. Its carbohydrate content depends heavily on how you measure it: dry couscous contains roughly 77 g of carbs per 100 g, while cooked couscous, after absorbing water, drops to about 23 g per 100 g. This calculator removes the guesswork when logging portions for carb counting or meal planning.
Enter your serving weight, choose grams or ounces, and select whether your portion is dry or cooked. The tool instantly estimates total carbohydrates, fiber, sugars, net carbs, and calories for that serving. It also shows the per-100 g value so you can compare different foods or update your nutrition log with confidence.
Use the quick-add buttons for common portion sizes or type in a custom weight. Values are based on standard USDA reference data for plain couscous.
Find total carbs, net carbs, fiber, and calories for any serving of dry or cooked couscous.

How This Calculator Works
The carbohydrate values used here follow standard USDA reference data for plain couscous. Dry couscous contains about 77.4 g of total carbohydrates, 5.0 g of fiber, and 0.15 g of sugar per 100 g. Cooked couscous, which has absorbed roughly double its weight in water, contains about 23.2 g of total carbohydrates and 1.4 g of fiber per 100 g.
The calculator applies a simple proportion to your portion weight. First it converts ounces to grams when needed, then multiplies the weight by the appropriate per-100 g value and divides by 100. The same process estimates fiber, sugars, net carbs, and calories so you can see the full macronutrient picture in one view.
Dry vs Cooked: Why the Setting Matters
Dry couscous is dehydrated semolina granules. When you add hot water or broth and let it steam, the granules absorb liquid and expand. A typical 45 g dry portion (about 1/4 cup) becomes roughly 150 g cooked couscous, or about one cup. The total carbohydrate in the batch does not change; it is simply diluted across a heavier cooked weight.
Choosing the wrong setting creates a large tracking error. For example, if you eat 150 g of cooked couscous but enter it as dry, the calculator will estimate about 116 g of carbs instead of the real value of roughly 35 g. That is an 80 g mistake — enough to throw off a day of macro tracking. Always match the setting to how you weighed the food.
Step-by-Step Guide
- Decide whether your portion is dry or cooked. Use dry for raw granules before cooking; use cooked for prepared couscous, leftovers, and restaurant portions.
- Weigh the couscous on a kitchen scale and enter the number in the weight field.
- Select grams or ounces. The calculator converts ounces using the standard factor 1 oz = 28.35 g.
- Press Calculate Carbs. The result area shows total carbs, carbs per 100 g, fiber, sugars, net carbs, and estimated calories.
- Use the quick-add buttons for common portion sizes, or change the weight to compare multiple servings.
Worked Examples
Example 1: Cooked side dish. You plate 200 g of cooked couscous. With the cooked setting, total carbs = 23.2 ÷ 100 × 200 = 46.4 g. Fiber = 1.4 ÷ 100 × 200 = 2.8 g. Net carbs = 46.4 − 2.8 = 43.6 g.
Example 2: Dry portion from a recipe. A recipe calls for 90 g of dry couscous. Total carbs = 77.4 ÷ 100 × 90 = 69.7 g. After cooking, that same portion will weigh roughly 280–300 g because of absorbed water, but the total carbs remain close to 69.7 g unless you add other carb-containing ingredients.
The contrast between these examples is a good reminder: a serving of cooked couscous can look much lighter in carbs per 100 g than dry couscous, but the total carbohydrate in your bowl depends on the actual amount of dry grain it started with.

Frequently Asked Questions
Is couscous considered a low-carb food? Not really. Couscous is a wheat-based starch similar to pasta. A one-cup cooked portion provides about 36–37 g of net carbs, so it can fit a moderate-carb meal plan but is difficult to fit into a strict ketogenic diet unless the portion is very small.
Should I weigh couscous dry or cooked for macros? Weigh it dry whenever possible because the dry weight is stable and matches package nutrition labels. Cooked weight varies with water absorption and steaming time. If the couscous is already cooked, weigh it cooked and use the cooked setting in this calculator.
Do whole-wheat or Israeli couscous change the numbers? Whole-wheat couscous has slightly more fiber, around 6 g per 100 g dry, and a few grams fewer net carbs, but total carbs are similar. Israeli couscous is made from the same semolina dough but shaped into larger pearls; its carb density is close to dry couscous, although portion volumes differ.
Why do the cooked values vary so much by label? The amount of water absorbed depends on the grain-to-water ratio, steaming time, and whether the couscous is drained. That can change cooked carbs per 100 g by a few grams. The values here are standard estimates, so for clinical applications use your specific food label and dry weight when possible.
