Calculate how much dry pasta to cook per person by shape. Get cooked weight, water amount, salt, and cook times for spaghetti, penne, fusilli, and more.
A pasta calculator determines the correct amount of dry pasta to cook based on the number of servings, pasta shape, and portion size. It accounts for the cooked expansion ratio and provides water and salt quantities for proper cooking.
| Shape | Cook Time | Expansion |
|---|---|---|
| Spaghetti | 8–10 min | 2.25× |
| Penne | 10–12 min | 2.1× |
| Fusilli | 10–13 min | 2× |
| Rigatoni | 12–14 min | 2.2× |
| Farfalle (Bow Tie) | 10–12 min | 2× |
| Angel Hair | 3–5 min | 2.3× |
| Fettuccine | 10–12 min | 2.2× |
| Elbow Macaroni | 8–10 min | 2× |
| Lasagna Sheets | 8–10 min | 2.5× |
| Orzo | 8–10 min | 2.8× |
Formula
Dry Weight = Servings × oz/serving × Portion Multiplieroz/serving = standard 2 oz (56g) per person for a main course
Portion Multiplier = 1× for regular, 1.5× for hungry portions
Cooked Weight = Dry Weight × Expansion Factor (typically 2–2.5×)

Did you know? Italy produces about 3.5 million tons of pasta per year — roughly 23 kg per person annually. There are over 350 recognized pasta shapes, each designed to pair with specific sauce types (source: International Pasta Organisation).
