  2. Length– distance from beginning of the side wall at the corner to the end of the side wall
  3. Leg Height– height of side legs of side walls from bottom of the ground to the attached of the bow, or truss which spans from one side wall to the opposite side wall
  4. Roof Pitch– normally built with a 3 on 12 pitch ( 2 on 12 also) this determines the height at the center of your building measured at the ridge cap.  The angle the roof rises to the peak of the building.
