The average American Staffordshire Terrier height is 18 to 19 inches for males and 17 to 18 inches for females. The male dog weighs around 50 to 70 pounds, while the female weighs 40 to 55 pounds.

Though all are descended from Britain’s bull and terrier, the American Staffordshire terrier is still a separate breed from both the Staffordshire bull terrier and the American pit bull terrier.
