Depends on your frame. If you have a small or medium frame you're good but if you've got a larger frame then you would be underweight. Honestly though..just as confused_one said...it really doesn't matter because the most important thing is that you're happy with who you are.
Depends are you a guy or a girl? I'm assuming you're a girl according to the female weight height chart ratio and your height Low Weight: 126 Target Weight: 146 High Weight: 167 So you are just right ;)
