Trunk up to 1 m (39 in) in diameter (rarely 1.4 m or 56 in). It reaches its largest size in southern Illinois and Indiana, although the national champion is 104' by 68' in Cincinnati, Ohio.

Bark: Light brown, scaly; on young stems light brown, smooth. Branchlets slender, dark green and shining at first, later become light brown, finally dark brown. Wood: Pale reddish brown, sapwood lighter; heavy, hard coarse-grained, checks badly in drying; used for shingles and sometimes in construction. Sp. gr., 0.7529; weight of cu. ft., 46.92 lbs.

Leaves: Alternate, oblong or obovate, four to six inches long, one to two inches wide, wedge-shaped or rounded at base, acute or rounded at apex, sometimes entire or with undulated margins, sometimes more or less three-lobed. They come out of the bud involute, bright red, covered with rusty down above and white tomentum below.

In autumn they become dark red above, pale beneath, midribs darken, then the leaf. Petioles stout, hairy, flattened, grooved. …

It is native primarily to the Midwestern and Upper South regions of North America, from southern New York west to northern Illinois and eastern Kansas, and south to central Alabama and Arkansas. It is abundant in the lower Ohio Valley and middle Mississippi Valley, and rare in the east. It is most commonly found growing in uplands with good drainage, less often along lowland streams, at altitudes of 100–700 m (330–2,300 ft).

In the past, the wood was important for making shingles, from which the common name derives.
