What are the difference between a red giant and a red super giant

Red giants are very large stars which are highly luminous and have an inflated outer surface with an approximate temperature of about 5000 degrees K or lower.

Whereas, Red supergiants are the largest stars in the whole universe in terms of volume but they are simply bright, red stars unlike the red giants.

Having said that, there are no agreed theoretical distinctions between the red giants and red supergiants so there is still a room for confusion to discriminate between the two.
