Using word 2002 with win 7;

Can someone tell me how to save a document at a certain zoom magnification? my document that I used opens up in 100% but I want to open it up at 150%. I can't figure out how to do this; it's driving me nuts; I can't seem to get any window to open in the format/style that I want to; at always reverts back to this 'default' display.
