Question: is 5'4 short for a 14 girl?
Answer: As you can see above, most females at age 14 grow just 0.5 inches after this age, ending up at 5′4.2″. The average American female at age 14 is 5′3.7″. Chances are that you'd end up at 5′4.5″, which is tall for an American female, and short for a British female (0.5 inches below the British average).
