Species

• Clemson University's Cooperative Extension service maintains that the growth rate of an oak tree is dependent on the species. Varieties like the pin oak will grow with approximately 18 inches per year, eventually achieving a height of 60- to 70-feet tall and 25- to 40-feet wide.
  
  

Types

• The white oak grows between 10 and 15 feet in the course of 10 to 12 years to a mature height of somewhere between 50 and 100 feet. The water oak shoots up more quickly, growing to a height of 25 feet within a decade and an eventual, mature height of 50 feet within 20 years.
  
  

Time Frame

• The willow oak grows 25 feet in 12 years and the Southern red oak accumulates a height of 25 feet in 20 years. An attraction of oak is its ability to grow within a reasonable period of time.
