There are usually two ways to resize, keeping the stitch count the same (which means the density gets higher when you reduce the size - something you don't want) or keeping the density the same (lowering the stitch count).
Choose the second one, if you change the size more than 10%.
My ARTSIZER (OESD freebie) reduces number of stitches when I make design smaller. Can not find any density settings on menus.
