I see no symmetry between width and height.

To make a window usable you need to decide how many columns you need
to fit into the window by customizing split-width-threshold.

By default it's 160 that means two horizontally split windows
with 80 columns in each that allows a comfortable use of each window.

OTOH, the window height has less relevance since most of the time
all windows are scrolled vertically.
