How Big Are Orange Trees?

Some mature orange trees can grow up to 50 feet.

The orange tree has been cultivated to achieve a variety of different sizes for both commercial and home growers. The specific height and width of an orange tree is dependent on the species and variety of orange tree.

Height

Sweet orange trees grow to a height of approximately 25 feet, although extremely mature trees can surge up to 50 feet, both forming a rounded crown with slender branches. Dwarf orange trees are cultivated to achieve a much smaller height -- a trait that holds advantages for both commercial and home growers.

Dwarf

The dwarf orange tree grows up to 5 or 6 feet tall at maturity. Commercial citrus growers like these trees because the trees' small size allows farmers to grow more per acre with fewer hedging and pruning costs, says the University of Florida.

Mandarin

Size is dependent on the particular species, such as the mandarin orange tree, Citrus reticulata. Mature mandarin trees can reach a height of 25 feet with a greater spread, says Purdue University's Department of Horticulture website. The mandarin orange tree tolerates cold much better than the sweet orange.
