Product review (5 stars): Not so hard, DIY, oven door glass repair.
This part fit my Kitchenaid double oven door model number KEBC208KSS04.  The piece of glass measures 10" x 19-3/4".  It was the inner-most piece of glass.  My son and I took the oven door apart and in 30 minutes we had the new glass in.  You have to remember where everything goes, my door has 3 separate pieces of glass and several parts holding each glass in place.
