Keeping this in consideration, how big is a blue giant?

At 29 times bigger than the Sun, it is not the largest star yet found, but it is the most luminous, shining at a whopping 8.7 million solar luminosities with its incredible surface temperature of about 53,000K. It also has somewhere between 265 and 315 solar-masses, making it the most massive star yet discovered.

Secondly, what type of star is a blue giant? Blue supergiants are supergiant stars (class I) of spectral type O.
