In many forests, this deciduous tree grows straight and tall, to 28 m (92 ft), exceptionally to 43 m (141 ft) tall, with a trunk of up to 50–100 cm (20–39 in) diameter. Open-grown trees do not get as tall, but can develop a stouter trunk, up to 2 m (6.6 ft) in diameter.
Under optimal conditions and full sun, northern red oak is fast growing and a 10-year-old tree can be 5–6 m (16–20 ft) tall.
The bark is dark reddish grey brown, with broad, thin, rounded ridges, scaly. On young trees and large stems, smooth and light gray. Rich in tannic acid. Branchlets slender, at first bright green, shining, then dark red, finally dark brown. Bark is brownish gray, becoming dark brown on old trees.
Winter buds are dark chestnut brown (reddish brown), ovate, acute, generally 6 mm long.
Leaves: Alternate, seven to nine-lobed, oblong-ovate to oblong, five to ten inches long, four to six inches broad.
Red oak acorns, unlike the white oak group, display epigeal dormancy and will not germinate without a minimum of three months' exposure to sub-40 °F (4 °C) temperatures. They also take two years of growing on the tree before development is completed.
