For most home cooking, a good starting point is 60–75 g (about ⅓ cup) of dry couscous per person when it’s a side dish, and 75–100 g (about ½ cup) per person when couscous is the main part of the meal.

Quick Scoop

  • As a side dish:
    • 45–75 g dry couscous per person (about ¼–⅓ cup).
    • This usually becomes roughly ¾–1 cup cooked couscous per person once hydrated.
  • As a main dish (e.g., big couscous salad or couscous with veggies and chickpeas):
    • 75–100 g dry couscous per person (about ⅓–½ cup).
    • This will give a generous portion with a bit of room for healthy appetites or small leftovers.
  • Simple rules of thumb:
    • Cooking for light eaters or many side dishes: aim closer to 45–60 g per person.
    • Cooking for hungry guests or couscous as the star of the plate: go up to 80–100 g per person.

Typical UK-style guidance

  • UK-focused portion guides usually suggest about 75 g dry couscous per person as a standard side, which cooks up to around 200 g cooked.
  • Many cooks use “⅓ cup dry couscous per person” as an easy visual measure that works well in everyday recipes.

In forum and recipe discussions

  • Home cooks often note that couscous roughly doubles in volume when cooked, so 1 cup dry makes about 2 cups cooked, enough for about 3–4 average portions depending on appetite.
  • People who like hearty grain salads or “meal prep” bowls frequently scale toward the higher end (around 100 g per person) to ensure filling servings and possible leftovers.
