Chestnut oak typically manifests as a robust, deciduous tree reaching heights of up to 60-70 feet (18-21 meters). Its bark is deeply furrowed with a distinctive, rugged texture. The foliage comprises leathery, elliptical leaves that span 4-8 inches (10-20 cm) in length with a rich, glossy green upper surface and paler underside. Fall transitions the leaves to a vibrant array of yellows and browns. The tree's acorns, which are encased in a scaly cap, provide a key distinguishing feature, measuring about 1-1.5 inches (2.5-3.8 cm) in length.
