Aspect ratio vs boundary layer

Hi! Everyone Someone told me in order to obtain good converged results I need to keep the grid aspect ratio low too. But how about at the boundary layer? A.R usually high at the boundary layer.

I usually consider something at about AR = 10~20 as acceptable. And depends on the local flow velocity so for something of high subsonic it would be better to keep it below 10.
