What we did (and this increased the height of the run above the six foot level of the dog run):
This run was only 7 feet wide. You might need to add additional supports to go the 12 foot width, especially if snow weight is a concern in your area. We used 3/4" pipe; 1 - 1 1/2 pipe would add more stability.
