you can use the terminal to make your wow's smaller than normal but the ratio restraints will stay the same.

use the following command then launch the clients you want smaller. note that you may want to change the .75 to a number better for you.

defaults write NSGlobalDomain AppleDisplayScaleFactor .75

after launching the clients issue

defaults write NSGlobalDomain AppleDisplayScaleFactor 1

to get new programs to launch at the standard size.
