Grid Unit % Adjustment
These two options apply only to dialogs using the Windows desktop font size grid, allow you to adjust the height and width of the grid unit without affecting the font size. This is a somewhat exotic technique, but might be handy if you find that your dialogs are either too spacious (in which case you specify numbers less than 100%), or two crowded (causing some of the text inside controls to be clipped), in which case you can increase the percentages. Or, a third situation would be that you feel that all your dialogs are either too tall and skinny or too short and fat, in which case you can adjust the percentages to get the desired aspect ratio. Note however that these adjustments are global (i.e. they affect all dialogs using the Windows desktop font size grid), so are of no use in adjusting just a couple of dialogs. (For that you need to modify the dialog design itself.)
