Weight and height are they looking for in a ballet audition

I want to be a ballerina sooo much!
no, I accept I will never be proffesional or anything but I want to be in my local ballet company and maybe some of associates classes and stuff.
I was wondering aswell as being talented what kind of height and...

weight are they looking for in a ballerina? (and dont say any, because I know its not true. I know it tall, slim and fit but any measurement? give me something to aim for?)

thanks in advance
