width of building

[redhead2]

When you set the poles for width of building, do you measure outside to outside of 4x4, or do you have to set poles in 11/2" from ea. side to allow for header that supports the trusses.
Say for example it is 27' wide by 40' long, would exact measurement be 27' or would it be 26'-9" from outside of post to outside of post

Is this something your designing? or is it a materials kit? I would think that you would need the truss design in front of you to determine where the header should be. In our country we put the trusses on the posts, not a header so I can't say how to do it on your design. And with all the different ways to build a pole building I would be suspicious of any answer you get here from someone who has not seen your building design.

If your designing this building and want to be efficient with materials think in numbers that are divisible by 2,3&4.
