Claudia Jordan's got Amy Schumer's back -- be it size 6, 7 or 8 -- in the comedian's weight war with Glamour magazine.

Claudia weighed in on the debate about the mag including Amy in its plus size edition. Schumer's pissed and CJ agrees ... the numbers just don't add up, but she's not surprised.

Watch her go off on Glamour for more than just weight.
