how big is our Sun compared to other stars ?

in dramatic and popular videos featured on YouTube, the relative sizes of planets, stars, and even the universe are shown from smallest to largest

the featured video begins with Earth's Moon and progresses through increasingly larger moons and planets in our Solar System

soon, the Sun is shown and compared to many of the brighter stars in our neighborhood of the Milky Way Galaxy

finally, star sizes are shown in comparison with the Milky Way Galaxy, galaxies across the observable universe, and speculatively, regions of a potentially greater multiverse

note that the true sizes of most stars outside of the Sun and Betelgeuse are not known by direct observation, but rather inferred by measurements of their perceived brightness, temperature, and distance
