The size of an oak leaf can vary significantly depending on the species, but they typically range from 4 to 10 inches in length and 2 to 6 inches in width. Some larger species, like the Northern Red Oak, may produce leaves that can exceed these measurements. The shape and lobing of oak leaves can also differ among species, contributing to their overall appearance.
