This matting fits a 15x21 frame with an opening size for a 11x17 photo / print (Actual opening size is 10.5x16.5). The reason for the smaller "actual" opening size is to create a .25" overlap on all sides so that the matting sufficiently covers and correctly adheres to the photo or print for proper display.
