Massive Stars and their approximate Size

Astronomers have found massive stars in the early universe, primarily located in distant galaxies that formed shortly after the Big Bang. These regions are often studied through advanced telescopes capable of observing very distant light, such as the Hubble Space Telescope and the upcoming James Webb Space Telescope. In terms of size, these monster stars can have diameters ranging from about 100 to over 300 times that of our Sun. The Sun’s diameter is approximately 1.4 million kilometers (about 864,000 miles), so these massive stars could be approximately 140 million to over 420 million kilometers (about 87 million to 261 million miles) in diameter.

Image: Hubble captures the IC 4653 galaxy

This image from the NASA/ESA Hubble Space Telescope shows IC 4653, a galaxy just over 80 million light-years from Earth. That may sound like quite a distance, but it's not that far on a cosmic scale. At these kinds of distances, the types and structures of the objects we see are similar to those in our local area.
