If yoiu goto menu View>Zoom, click the custom button and input your value.

 So far, using Excel 2002, the zoom settings I've seem give me either 75% or 100% (plus others) but nothing in between.  Is there a way to adjust the spreadsheet size to 80% or 90%?  When I try the Selection choice the zoom goes to 319%, sometimes 400%, and when I click on the negative zoom icon the sizes drop neatly from 400 to 200 to 100 to 75, again with nothing in betweem.

 Is there a way to a finer adjustment?

I'll answer this myself, since I figured it out...you can manually enter a specific zoom amount in the little zoom window line.
