The Sun's equatorial radius is about 6.955×108 meters
Many stars are around this size. There are stars such as Betelgeuse that are significantly larger (about 936 times the diameter of our Sun)....
Actually, compared to other stars the sun is just a medium sized star. For example, if you compare our sun to Beetlejuice(if I spelled it right), the sun would be just smaller than it.
The sun is bigger than some stars, but it is smaller than some stars too. The sun is the brightest star that is closest to earth, causing it to be seen daily.
