We use tall mostly for people, trees, buildings with many floors, and a few other things which are higher than they are wide (e.g. factory chimneys).
How tall are you?
I'd like something cool to drink in a tall glass.
In measurements, we use tall for people, but we often use high for things.
I'm six feet tall.
That tree is about eighty feet high/tall (both are okay)
HTH :)
