Even small tomato varieties have substantial root mass. The minimum pot size for a patio tomato should be 14 inches in diameter, with a capacity of at least 5 gallons.

I'm a tomato fanatic and grow them primarily for food, not for looks, so I put one plant per container (unless it an Earthbox or an enormous container or raised bed). Lots of people suggest growing herbs and other plants in the pot too. Not me. It's hard enough to give tomatoes the consistent amount of moisture they need without throwing in other plants that will compete for the water. Also, fill up that large container with a good quality potting soil and make sure you have good drainage.
