Amy Schumer is schooling Glamour magazine on “plus size.”

The comedian took to social media Tuesday after discovering her name on the cover of the mag’s “special edition” for plus-size women “without asking or letting me know and it doesn’t feel right to me,” Schumer, 34, said in a lengthy Instagram post.

On the cover, under a headline “Women Who Inspire Us,” the “Trainwreck” star is listed along with Melissa McCarthy, Adele and the issue’s cover model, Ashley Graham.

“I think there’s nothing wrong with being plus size,” she stated in the post. “Beautiful healthy women. Plus size is considered size 16 in America. I go between a size 6 and an 8.”

But “Young girls seeing my body type thinking that is plus size?” she continued, asking her followers: “What are your thoughts? Mine are not cool glamour not glamourous [sic].”

Posing the same question to her followers on Twitter, she got some celebrity responses.

“I find ‘special editions’ problematic in general, or at least specious, in that they frame the content as ‘other,’” tweeted “Portlandia’s” Carrie Brownstein.

Meanwhile “Saturday Night Live” cast member Aidy Bryant responded to Schumer on Twitter, “& u kno [sic] my ass was available.”
