Blue supergiants can be anywhere from 10,000 to 1,000,000 times brighter than the Sun, depending on their specific type and stage in the stellar evolution process. Generally, their luminosity is significantly higher due to their large mass and high temperatures. For instance, a prominent blue supergiant like Rigel is about 120,000 times more luminous than the Sun.

Which is brighter larger stars or smaller stars?
Brightness is related to distance. However, from the same distance, an O class star is much much brighter than a M class star. As a comparison, an O class star would appear about 100,000 times brighter than our Sun, whereas a M class star could appear 0.0017 dimmer than our Sun, if the Sun was replaced with each star.
How big is a Blue supergiant?
Blue supergiants are among the most massive stars known, with sizes ranging from around 10 to 50 times the mass of the sun. Due to their high luminosity and temperature, they can be hundreds of times larger than the sun, with radii ranging from 10 to 50 times that of the sun.
