How big did violet beauregarde get?

Violet Beauregarde, a character from Roald Dahl's "Charlie and the Chocolate Factory," becomes enormous after chewing a piece of experimental gum that causes her to swell up. By the time she is taken to be juiced, she has inflated to the size of a giant blueberry, which is described as being so large that she can barely move. This transformation serves as a cautionary tale about the consequences of greed and disobedience.
