Well there are different types.

This link has THE table of the largest stars you are looking for!

Our Sun, the star at the center of out solar system is a type G3
star which is a typical star in magnitude and size.
It is 886,000 miles in diameter.

This link table lists star diameters in terms how many TIMES
in diameter these stars are compared to our sun set to 1.

The Sun is about 800,000 miles in diameter. That is 100 times the diameter of the Earth. Some stars are smaller, red dwarf stars are not much larger than Jupiter which is "only" about 80,000 miles in diameter. Some stars are REALLY large. Red giant stars can be larger than the Earth's orbit, which is almost 200,000,000 miles in diameter!

The size (diameter or radius) of stars varies depending on their mass,
their energy output (called the luminosity) and their surface temperature.

The largest stars are red (cool) supergiants. They are about 1000 times
the size of the sun. The sun is about 100 times the size of the earth or
diameter of the sun=1.4 million km. The smallest regular stars are red
(cool) dwarfs. They are about 0.1 the radius of the sun.

Besides regular stars (i.e. stars that produce energy by nuclear
reactions), there are also three types of stellar remnants (i.e. objects
that have used up all their nuclear fuels). They are White Dwarfs,
Neutron Stars and Black Holes.
White Dwarfs are about the size of the earth, Neutron Stars are about 10-
20 km in diameter and Black Holes have a radius in km = 3x mass of the
star in solar masses.

radius squared of a star = Luminosity/(4 pi Stefan Boltzman constant x
Temp to the 4th power)
[R^2=L/(4 pi sigma T^4)

You can find the formula in most Introductory Astronomy books on the
Chapter dealing with the properties of stars.

For example, Foundations of Astronomy by M. Seeds (4th ed) p174

Stars are very very small specs of light in our sky. I'd say the flashlights are probably 5 or 6 cms. =]

some may be very big (even bigger than the sun) and some may be small...
