Dry to Cooked Pasta Calculator — Weight Conversion
Find out how much cooked pasta you get from a given amount of dry pasta, or how much dry pasta you need for a set number of servings. Choose your pasta type to get the right expansion ratio — different shapes absorb different amounts of water.

How does this calculator work?
Multiply dry pasta weight by the expansion ratio to get cooked weight: cooked = dry × ratio (roughly 2.0–2.3× depending on shape; egg noodles ≈ 1.5×). A standard serving is 75–80 g dry. Track calories using dry weight — nutritional labels are written for uncooked pasta.
Formula
How this is calculated
Pasta absorbs water during boiling and roughly doubles to 2.3× its dry weight. The exact ratio depends on the pasta's shape and surface area: thin strands like spaghetti absorb proportionally more (around 2.25×) while denser tubular shapes like macaroni absorb slightly less (around 2.0×). Egg noodles are made with egg solids and expand less (around 1.5×).
The ratios used in this calculator are approximate averages based on standard cooking times to al dente. Actual absorption depends on cooking time, water temperature, altitude and the brand of pasta — cooking longer means more water absorbed and a higher cooked weight. For counting calories, dried pasta weight is more reliable since manufacturers publish nutritional values per gram of dry pasta; cooked weight varies too much by cooking time.
For serving sizes, a typical portion is 75–80 g dry pasta per person for a main course or 50 g for a side dish. The calculator shows both the cooked output from your dry weight and the dry input needed for your chosen number of servings at a standard portion size.
Frequently asked questions
Yes, approximately. Most dried pasta roughly doubles to 2.2–2.3× its dry weight when boiled to al dente. Egg noodles expand less (around 1.5×) and orzo a little more. Cooking for longer than the recommended time increases the water absorbed further.
Dry is more reliable. Nutritional labels state calories and macros per gram of dried pasta, and the dry weight is the same regardless of how long you cook it. Cooked weight varies significantly with cooking time and draining method, so tracking by dry weight gives consistent results.
A typical main-course portion is 75–80 g of dry pasta per person (around 2.5–3 oz). For a lighter side dish or a pasta salad, 50 g per person is common. These are general guidelines — adjust to appetite and the richness of the sauce.
