400 g (14.1 oz) cooked Spaghetti

  • Spaghetti expands by a factor of 2.0 when cooked, so 200 g dry yields 400 g cooked (about 3.1 cups).
  • That works out to 200 g cooked per person across 2 servings.
  • A standard restaurant main-course portion is roughly 180-220 g cooked pasta (about 85-100 g dry).
  • Pasta continues to absorb sauce and moisture after draining, so cook 10-15 % less if you plan to finish it in the pan.

Next stepFor an even more accurate result, weigh the dry pasta rather than measuring by volume, since shapes pack differently into a cup.
