How much does pasta grow when cooked?
Dry pasta absorbs water as it boils and typically grows to about 2 to 2.2 times its dry weight once cooked, depending on the shape and cook time. This calculator uses an average ratio of 2.15x to convert between dry and cooked pasta weights.
Using this for meal planning
A common serving size is around 200 grams of cooked pasta per person for a main course, or less for a side dish or starter. Enter your desired cooked serving size to see roughly how many servings your dry or cooked amount will produce.
- 100 g dry pasta โ 215 g cooked
- Cooked pasta รท 2.15 โ dry pasta needed

Actual yield varies by pasta shape, brand and cook time, so treat this as a helpful planning estimate rather than an exact measurement.
