How far apart are the two posts of a field goal?

Answer:

The goal posts @ Collegiate and Professional levels are 18'6" (eighteen feet & six inches) apart, supended by a crossbar which is 10' (ten feet) off the ground. The uprights (the two posts) extend 30' (thirty feet) into the air, making for a total height of the goal posts of 40' (forty feet) off the ground in total.
