Your plans call for 22 5 degree cuts with 6ft 6in length on the apex.

How to build trusses for 12 ft wide roof. These will include wood a hammer a saw roof truss. Select or determine a pitch or angle of slope. The more complex the truss framework is the greater quantity of these joints will be required. These steel joints are needed to support the overall truss.

2 uprights are sufficient for 8 10 and 12 wide trusses. These dimensions leave the truss 3 4 inches short of covering the 12ft wide building and 6inches short of the 10 ft height.
