    Hi Jamie: Here is a site I found regarding angles. It may help: https://www.dummies.com/education/math/geometry/how-to-measure-angles/ What ever you do, get some scrap wood and practice, practice, practice. Like they say, measure twice, cut once.


    Here is a site that is specifically for the Z look. You can adjust the sizes to accommodate your size. http://www.brandisawyer.com/2014/03/diy-barn-doors.html


    Good luck

    The angle would not be the same based on the height and width of the door. It would change with the H and W of the door. If you can't calculate the angle or don't have an angle gauge use a piece of cardboard?paper as a template.

    Why go about it the hard way? This is what Efficiency Engineers are paid to do: Eliminate Difficult Math. So, Turn your boards like an N and plant a Bolt Dead Center at the 45° of each of both ends of 'Z Longest Board' at the Bottom. You align it and make your marks with a pencil, then cut to the marks. It will turn out Perfectly Done Every time.
