There are two ways of comparing size: Mass, and volume. (Mass is the product of volume and density).
Our sun is about average, perhaps a little above. It is expected there are lots of small red dwarf stars, which begin fusing hydrogen up around 15 Jovian masses. Since our sun out masses Jupiter by a factor of several thousand, the smallest stellar mass would approximately be one hundredth the mass of our sun. Note: there may be special circumstances a sun could be even smaller--see the link below.
As for diameter, white dwarf stars could have diameters of 7000 miles--that is even smaller than our earth (8000 miles). Neutron stars are even smaller yet, with diameters up to one half mile, yet with roughly the mass of our own sun.
The biggest stars can have masses hundreds of times that of our sun, and correspondingly large diameters.
larger in diameter, more dense, average in mass
Average
The sun's diameter is about 865,374 miles. Its density is 1.622�105 kg/m3 and its mass is (1.98855±0.00025)�1030 kg which is 333,000 times that of Earth.
No. Stars vary in lots of aspects, including:* Diameter * Mass * Color (and the related surface temperature) * Chemical composition * Density (related to mass and diameter) * Brightness
because those stars have high luminosities.
That's because the Sun is so close to us compared with other stars.
Yellow stars are the second hottest, Blue stars are the first hottest. Red stars, even though they are they can be the biggest they are the coldest type of star, they are still hot, but not as hot as compared to other stars.

When compared to the other stars, the Red Giant Star are very minute. There are other stars that are very large by far as compared to the Red giant stars.
Nothing, really. The Sun is average in size, temperature, and density. Its an all around average star.

Our Sun is well above the median; probably somewhere around percentile 85 or 90, both with respect to mass and diameter. That means that 85% or 90% of the stars are smaller than our Sun.

what is unusual about the sun compared to many other stars ?????#
The Andromeda galaxy (M31) has in recent years been found to have an extended range of faint stars previously unseen, giving the galaxy an overall diameter of about 220,000 light years (~67.5 parsecs). This was roughly three time previous estimates. What proves difficult in pegging a specific diameter is that galaxies do not have hard edges. The field of stars dwindles in density somewhat gradually. We have to define at what density of stars is a location no longer within the body of a galaxy. This definition would be rather arbitrary and could vary from person to person.
What you measure something in depends on what property you want to measure. For example, whether you want to measure the star's diameter, its density, its surface temperature, its mass, etc.Two measurement systems are often used: 1) SI units, for example, diameter in kilometers, mass in kilograms, etc. 2) Some properties, and especially diameter and mass, are often compared with the Sun's mass; for example, a certain star might be said to have 2.1 times the mass of the Sun.
The sun is larger than some stars but smaller than others. The smallest stars, not counting collapsed remnants, are about a tenth the diameter of the sun. The largest are more than 1,000 times the sun's diameter.
Some stars are much larger than our Sun - up to several hundred times its diameter - some are smaller than it. Most, however, are smaller; the Sun is in the top 10% with respect to mass, and probably also with respect to diameter. The large majority of stars is of the "red dwarf" type.Some stars are much larger than our Sun - up to several hundred times its diameter - some are smaller than it.
