That is entirely dependent upon how much matter is available during the star's incubation period.

The picture above is the Karina Nebula. This is one of the billions of breeding grounds for stars in the universe. What appears to be clouds surrounding these stars is the material needed to create new stars, hydrogen. When the hydrogen atoms pool and start to cling to one another they gain mass. As their mass grows they attract more and more material until the mass reaches a sort of ignition point, the point at which the gravity associated with the hydrogen is so great it sets of nuclear fusion reactions.

A star will grow until it has collected all the hydrogen available to it. The amount of available hydrogen dictates the size of the star.
