We are in the process of remodeling our kitchen and are having a problem figuring out which size upper cabinets to use. The ceilings in our kitchen are 90 inches and will be using IKEA cabinets so our only choices are 30 or 39, without modifying them - which we really don't want to do. I like the idea of the cabinets going to the ceiling but i'm not sure that's a wise idea with such low ceilings. Would it better to use 30 inch cabs and a few inches crown molding to the ceiling instead? Any input would be greatly appreciated.

Thank you
