set geometry of kedit

This may be a general question about all kde menu items but I see no way to adjust the geometry of kedit. Rigth/left click on the menu item just brings it up. Using menu editor I see a place to set the command line but after looking at the kde help brower on kedit... I didn't see talk of geometry settings. The (starndard for older linux apps) `-geometry' doesn't do it. Seems to have no effect at all like this: kedit -geometry 90x120& Still starts in too small a terminal.
