For Example: Calculate the length of the maximum height of the king post in a roof truss to ensure that the slope of the roof is less than 10°. The width of the house will be 40 feet. 40ft tan 8 = opp adj X tan 10° 20 ft 20 ft • tan 10° = x x = 3.52 ft Therefore the king post should be no longer than 3ft 6in.
