The Hungarian oak is a tall, but short-stemmed tree (up to over 30 m), which initially forms an egg-shaped, later more spherical crown. The bark is light gray, sometimes brown, and interspersed with a dense network of cracks and furrows. The bark of young twigs is initially softly hairy, later bare. The leaves are oblong to obovate, 10 to 20 cm long, 4 to 12 cm wide, deeply incised with seven to ten lobes on each side, green on top, more gray below. The leaf stalks are a maximum of 10 mm long.

The fruits (acorns) sit together in twos or four, are up to 2 cm long and at least one third is surrounded by the hemispherical cup.
