Between 1.6x10^29 kg and 2x10^32 kg (early stars made of primordial gas (all hydrogen an helium) may have been stable at much larger sizes ).
In radius they can range from a few km for a neutron star (a corpse star) to earth size for white dwarfs, to maybe Jupiter sized for the smallest main sequence (fusing hydrogen in their cores) stars. The biggest puffiest red giants (generally fusing hydrogen or perhaps helium in spherical shells around the core) can be several thousand times the radius of the sun; as large as the size of Mars' orbit. (Keep in mind that the gas of such a star will be pretty diffuse when it is all puffed out like that.)

Stars come in many sizes. Compared to all the planets in the solar system, the sun, a star, is huge. But the sun is a small star. Some stars are 100 times bigger than the sun, some, called red dwarfs, are much smaller. Most of the stars you see in the night sky are huge blue stars. They are blue because of their temperature. Stars the size of the sun you can't even see unless they are really close. For instance, if you were on a planet circling the north star, Polaris, looking back in the direction of the sun, you couldn't even see the sun, it would be that small and dim. That's how small and insignifigant the sun and earth really are compared to the rest of the galaxy.

Stars are the suns of other solar systems seen from extremely far away. So technically stars are very, very big.

there is no specific shape or size of the stars it depends on the mass of the star that how much gases in watt mass it contains star can be more then hundred times bigger of sun and can be like same as earth or sun.
all it depends on the quantity of gases in it.
as simple as that if any body have any queries mail me up any time!!!!

they differ in size, but are still very very very big.
i tihnk our sun is only a medium-sized dwarf star - so there are alot of stars out there bigger than our sun.

As small as a full stop.
