Chimney Cap Sizing Guide: Proper chimney cap sizing requires accurate measurement of both the inside and outside of the flue tile. There are no standard flue tiles. The size and wall thickness of chimney tiles are extremely varied, depending on the region and when a chimney was built. For this reason, accurate measurements (to the nearest 1/8'') are imperative to correctly size a chimney cap.Hy-C Stainless Steel Combo Chimney Cover 9'' x 13'' (fits outside flue tile size from) 7 1/2''' x 11 1/2''' to 9 1/2''' x 13 1/2'''
