It is a deciduous tree to 20-30 m tall with a broad, rounded crown and grey-brown, shallowly grooved bark; unlike many other species of maple, mature trees do not tend to develop a shaggy bark. The leaves are opposite, palmately lobed with five lobes, 12-25 cm across. The leaf stems secrete a milky juice when broken. The flowers are in corymbs of 15-30 together, yellow-green with five petals 3-4 mm long; flowering occurs in early spring after 30-55 growing degree days.

The fruit is a double samara with two winged seeds, the seeds are disc-shaped, strongly flattened, 10-15 mm across and 3 mm thick. The wings are 3-5 cm long, widely spread, approaching a 180-degree angle. It typically produces a large quantity of viable seeds, a factor which contributes to its invasive character.

A number of species of Lepidoptera feed on Norway Maple foliage; see list.

Many cultivars have been selected, with distinctive leaf shape or coloration such as the deep red of 'Crimson King', the variegated leaves of 'Emerald Queen', and the deeply divided, feathery leaves of 'Dissectum'.

It has been widely introduced into cultivation in other areas, including western Europe northwest of its native range. It grows north of the Arctic Circle at Tromsø, Norway. In North America, it is grown as a street and shade tree. It is favoured due to its tolerance of poor, compacted soils and urban pollution. As a result of these characteristics, the Norway maple is displacing native hardwoods such as oak in some parts of North America and is considered invasive in some states, but is still considered fine for urban plantings in many areas. Norway Maple itself is threatened in a few areas by the Asian long-horned beetle, which eats through the trunk of trees, often killing them. there plants
