I'm especially interested in the recommended depth for an armoire that
would have a clothes-hanging rod in the usual orientation: parallel to
the back. Also the height of the clothes-hanging area. Let's assume it's
for shirts and pants folded over hangers. No dresses. No outerwear.

Way back when I was a draftsman doing house plans, I was told
to never make a closet narrower than 16" because otherwise the
hangers wouldn't hang straight. Usually we aimed for 20-22".
