depends on their age; for someone in their 50s, say, it'd still be within the normal range; for someone young, it would be on the short side as young people today are taller than their parents.
I am 5'10, but I still wear heels - my hubby is 6'2 though, so that is fine - my 6 year old is 4'2 and is catching up on my sister in law who claims to be 5 foot tall, but the jury is still out on that one! She did however manage to produce my nephew who is 6'1 and niece at 5'5. Height is all relative, just hang out with short people!
