What size pot do you need?
Quick answer
One pound of dry pasta wants four quarts of water, and with headroom that means at least a six quart pot. For soup, allow about a quart and a half per person plus 60 percent headroom, so four people need about a nine quart pot. Never fill a pot more than halfway with frying oil.
Portion sizes and headroom allowances are kitchen conventions rather than specifications. The capacities are real; how hungry your household is, only you know.
The long-standing rule is four quarts of water per pound of dry pasta, which means a one pound batch wants at least a six quart pot to avoid boiling over. Cooking pasta in far less water also works and gives starchier, more useful cooking water; the large pot mainly buys you a stable temperature when the pasta goes in.
One pound of pasta, soup for four, a small stock.
Headroom is not padding. A pot filled to the brim boils over the moment starch foams or a lid goes on, and an overfilled frying pot is the usual cause of a kitchen oil fire.

Common questions
Do I really need four quarts of water per pound of pasta?
It is the long-standing rule and it buys you a stable temperature: a large volume of boiling water barely drops when cold pasta goes in. Cooking pasta in far less water also works perfectly well and gives starchier, more useful cooking water for the sauce. What the large pot really prevents is the pasta clumping while the water struggles back to a boil.
Why does a pot need so much headroom?
Because liquids foam and climb. Starchy pasta water and simmering stock both throw up foam that rises far above the liquid line, and putting a lid on traps steam and pushes it higher still. A pot filled to 80 percent will boil over; one filled to 60 percent generally will not. Headroom is also what makes a full pot safe to carry.
How full can a pot be for deep frying?
Half full at most, with at least three inches of clear space above the oil. Wet food dropped into hot oil makes the oil boil violently upward, and an overfilled pot lets it go over the rim onto the burner. That is the usual way a kitchen oil fire starts. If a fire does start, cover the pot with a metal lid and turn off the heat. Never use water.
Is a taller pot or a wider pot better?
It depends on whether you want evaporation. A tall, narrow pot has a small surface area, so a stock reduces slowly and stays clear, which is what you want. A wide pot evaporates fast, which is what you want for reducing a sauce. For pasta and boiling, width mostly helps by giving more contact with the burner.
Can I use a dutch oven instead of a stockpot?
For anything up to about six quarts, yes, and usually better. A dutch oven has thick walls and holds heat, which suits braises and long simmers. For pasta and large stocks a thin disc-base stockpot is actually preferable: it is far lighter to lift full, it comes to the boil faster, and the wall thickness does nothing useful when the job is boiling water.
