Enter your dry couscous amount and number of servings to get the perfect water-to-couscous ratio and cooking time. The Couscous Cooking Calculator tells you exactly how much water to use, the total yield after cooking, and step-by-step timing — so your couscous comes out fluffy every time.

For regular instant couscous, the standard ratio is 1:1.5 — meaning 1 cup of dry couscous to 1.5 cups of boiling water. Whole wheat couscous typically needs slightly more water (1:1.75), while Israeli pearl couscous requires 1:2 since it is simmered rather than steeped.
Regular instant couscous only needs to steep in boiling water for 5 minutes off the heat. Whole wheat couscous benefits from 8–10 minutes. Israeli (pearl) couscous is simmered on the stovetop for 10–12 minutes, and Lebanese (Moghrabieh) couscous can take up to 20 minutes.
Clumping usually happens when the couscous is stirred too much during steeping or when too little water is used. To get fluffy couscous, pour the boiling water over the grains, cover tightly, and leave untouched for the full steeping time. Then fluff with a fork — never a spoon — and add a small knob of butter or a drizzle of olive oil.
Dry couscous roughly doubles in weight and volume when cooked. As a rule of thumb, 100g of dry couscous yields approximately 200–220g of cooked couscous. This calculator uses a 2.1× yield multiplier for regular couscous.
Yes — substituting vegetable, chicken, or beef broth for water is one of the best ways to add flavour to couscous. Use the exact same volume of broth as the water amount this calculator provides. The ratio and timing remain identical.
As a main dish, allow about 75–100g of dry couscous per person. As a side dish, 50–75g per person is usually sufficient. This calculator defaults to 50g per serving as a side portion and scales linearly with the number of servings you enter.
Whole wheat couscous has a nuttier flavour and chewier texture. It absorbs slightly more water (ratio 1:1.75) and benefits from a longer steeping time of around 8–10 minutes. The cooking method is the same — boil water, pour over couscous, cover and steep — but the extra water and time are important for proper texture.
Israeli couscous (also called pearl couscous) is larger and toasted, giving it a chewy, pasta-like texture. Unlike regular couscous, it must be simmered in boiling water or broth for 10–12 minutes rather than just steeped. It uses a 1:2 water ratio and should be drained if any excess liquid remains after cooking.
