I think one cup is a serving, but I don't have a food scale so I can't say for certain.
What I do when cooking spaghetti is look at the box to see how many servings the whole box makes, usually 8. Then, by dividing that up, I can tell how much one serving would be. For example, I usually only make 1/2 a box at a time, or 4 servings. It is easy to separate the cooked pasta in half, then half again to get 4 equal portions, 2oz each. In my experience, each serving of cooked spaghetti comes to about a cup.
