Guys, is 5'7 a good height for girls? Too short or too tall, what do you think?

I don't even bother to recalculate your numbers into metric to understand it. Your height is perfect for you! It is not as if you can do anything about your height now anyway.

A guy will fall in love with you, and your height is part of that package. So asking the question makes no sense. Yes of course it is a good height for girls, or at least a girl - namely you.

You could ask if I as a man prefer girls to be your height, shorter or taller. But that is a totally different question. My response is generally: "Yes, please. All of the above."

It's a good height. It's not short at all but it's above average though.
