The Bible does not specifically say how old he was but it does call him a "youth," which probably means about 12-16 years old.
A:1 Samuel 17:4 calls Goliath a champion of the Philistines, suggesting that he was a great warrior who had indeed fought before. On the other hand, serious historians do not regard the story of David and Goliath as based on fact. Even Chronicles, in recounting the story of David, entirely omits the story of David and Goliath, suggesting that the Chronicler did not really believe the story. Historically, the giant Goliath had never fought before and did not fight David.
In the bible the battle between Goliath and David was fought on the plains called Ela also called the Valley of Elah. The full story can be found in 1 Samuel 17.
Around seventeen, I think. He had fought bears and lions defending his sheep, but was still too young to be in the army.
This is something which is not revealed in the historical account of the encounter and so will probably never be known. 67

The battle in which David hurls the stone in his sling and brings the enemy champion down. Then with Goliath's own sword David decapitates him, and he returns to camp with the trophies of war, the giant's head and sword. (1Samuel 17:37-54)
