White oak
vs
Northern red oak

White oak's acorns sit in a rough, warty cup covering a third to half of the nut and have been called sweet; northern red oak's sit in a shallow, saucer-shaped cup and have a bitter kernel. White oak's bark is rough and scaly; red oak's is gray with shallow furrows and low ridges, turning checkered. White oak grows slowly and can live 600 years; red oak is the tallest and fastest-growing oak. In autumn white oak turns purplish-red to violet-purple.

White oak
vs
Swamp white oak

White oak's acorn cup is rough and warty; swamp white oak's is mossy and fringed. White oak is missing from poorly drained flats and very wet bottomlands, which is where swamp white oak grows, along with river bottoms and swamp edges.

White oak
vs
Bur oak

White oak's rough, warty acorn cup covers a third to half of the nut; bur oak's covers at least a third and can cover all of it. Bur oak's big leaves (up to 12 inches) are deeply lobed and white-hairy beneath. White oak can live 600 years, bur oak commonly 300 to 400; bur oak also grows out on prairies and sandhills.

The white oak, in short

US Forest Service species review
Size
Commonly 60 to 80 feet tall, spreading; on good sites more than 100 feet tall and over 5 feet across.
Lifespan
Slow-growing and long-lived, up to 600 years.
Bark and fruit
Rough and scaly, and more fire-resistant than the solid bark of many other oaks. Acorns tan to brown, usually in pairs, in a rough, warty cup covering a third to half of the nut.
Where it grows best
Rich uplands, moist bottomlands, stream banks, sandy plains and dry, gravelly slopes, on every slope direction; missing from shallow-soiled ridgetops, poorly drained flats and very wet bottomlands.
Shade
Can't regenerate under a dense canopy, not even its own; it has relied on periodic fires to keep its place.
Wildlife
Its acorns are choice food for white-footed mice, squirrels, black bears, rabbits and many birds, from blue jays and bobwhite to wild turkeys, ruffed grouse and mallards. Gray squirrels eat them but prefer other oaks' acorns. Porcupines eat the bark and beavers the twigs.
People and uses
A common shade tree, prized in autumn for purplish-red to violet-purple leaves. Its acorns, called sweet by some and slightly bitter by others, were an important food for many Native American peoples, often boiled to remove the tannins.
