how to deremine boundary layer height?

I have faecd a fact that from manual thet when u are going to capture near wall region you have to refine mesh at near wall region ,and your y plus should be in limit of 11.In your boundary layer there should be 10 nodes.but how to determine this hight.i.e. there should be these much nodes in this hight so that we can mesh according to that. Thaks in advance.

Dear Mr. Mike

I have a question. For using wall function, we should have a yplus greater tha 50, since the log law is satisfied in this yplus. Isn't it?
