How To Frame Gable Roofs 12

Calculating Gable End Stud Length By Ratio And Proportion

The gable end stud length difference can be calculated by ratio and proportion as shown on figure 43. If the studs are to be at 600 mm o.c. and the unit rise is 150 and the unit run is 250, the difference in stud length X will be X divided 600 mm = 150 mm divided by 250 mm. The difference in stud length is 360 mm. Subtracting multiples of this distance from the longest stud will give the lengths of the other studs.
