Standard Height of moulding?
Welcome to the forum silbella.
I don’t think there is really a “stranded height” but if there was it would be closer to 1/3 up the wall rather than 2/3. The picture you show is to high IMO.
The ones I’ve done have been from 32-40”. The height being determent by things like window sill height and other things in the room and how it will all tie together. Basically it can be whatever looks good to you.
