Thank you for your feedback, Scott. We sincerely apologize for any confusion on the sizing of the Masonite 60 in. x 80 in. Willow Wood Steel Prehung Left-Hand Inswing Mini Blind Patio Door without Brickmold @ The Home Depot . It is an industry standard for components like door slabs, wood bucks, etc. to not be what is called the "call” or nominal” size. These terms are used in the industry that are rounded measurements to the closest actual size. The standard size that we offer for any exterior steel door unit that we provide from our company which will be 31.5" x 79". If you have any additional questions, please do not hesitate to contact us via email at helpline@masonite.com. Sincerely, Masonite
