Traditionally, golf clubs are all different in length, with each club getting progressively shorter as the loft increases. So, for example, your 5-iron is slightly longer than your 6-iron, which is longer than your 7-iron. Since 2011, Bryson DeChambeau has been playing irons and wedges that are all the same length, 37.5 inches, which is the length of a traditional 7-iron. So, his higher-lofted irons are longer than standard, but his low-lofted irons are shorter than conventional length.
