sizeism

noun

1. (uncountable)Discrimination based on a person's size (such as height, girth, or weight).

   “Sizeism is hard to avoid on dating apps such as Grindr and Tinder, where users commonly forbid men under 6ft from contacting them. Tinder even made a 2019 April Fool’s joke about launching a “height verification” update that would prevent guys from exaggerating their stature.”
