How Do You Calculate the Height of the King Post?

Asked by Thomas on April 13, 2018

how do you calculate the height of king post of the roof structure?

Answered by Caitlin

King Post Truss in the Westbrook Middle School in ME.

Hi Thomas,

It is just simple geometry. For instance, a 24 foot truss with a 12/12 roof pitch would have a height of 12’. A 6/12 roof pitch would have a height if 6’

12/12 means there is a 12” rise for a 12” run. 6/12 is a  6” rise for a 12” run.

Cheers,

Doug
