My old microwave was 37 years old, but quit working safely, but I measured the inside, outside and calculated this into inches and then into cubic feet, as well. Height x width x depth=Cubic feet ( 12 inches= 1 foot. ) This new Insignia measures about 11 inches square interior , has a 10 inch rotating glass plate, on rollers, and a entrance height of 6.5 inches. That's big for .7 cubic feet ! Then I knew this size to shop for, actually taller, and would work since I was happy with the size I had been using. The new exterior is 15 inches across, 10 inches height and 12 inches from back to front ( depth). I have the same spot and space in my kitchen to place it. I looked at my appliance colors, and they were white, which Best Buy offered. I read customer reviews from people who actually had bought and used this exact microwave. They were very good. The number of reviews was 1,000 and averaged a rating 4.5 stars. That was terrific ! I compared it to a couple other microwaves that did not suit me with comments, both positive and negative, sizes, prices and numbers of reviews and stars. This microwave had everything I wanted, size= interior and exterior, a warranty, color and free shipping and a best price from any store I researched. I felt confident ordering it and waited eagerly for its arrival and felt like it was a Christmas gift to myself ! It's easy to use and looks wonderful. I love it.
