Simply hover your mouse over the folder.

Hmmm...mine doesn't do that. I don't get size info until the contents of
the folder are selected.

before opening it, when it's in the right pane.
windows seems to calulate it on the fly, so if the folder is big it takes a
while.
for a folder whose properties say 15.8 gb, the tooltip in explorer after a
couple seconds said 'bigger than 2.45 gb'.
