Standard Roof Truss Sizes

The truss is a framework consisting of rafters posts and struts which supports your roof.

Standard roof truss sizes.

Girder trusses are designed to carry additional loads other than standard roof loads. Common or standard trusses are symmetrical and have standard four inch heels. The standard roof truss spacing is 2. This is the distance between trusses.

You will also incur additional costs because it is much harder to deck and shingle a roof that is 12 12 pitch versus a 4 12 roof. A truss with the same pitch and heel on both sides and a peak at the center is called a common truss. The important point to keep in mind when you use your truss calculator is that every truss calculation is completely unique and is based on the size of your roof and its specific dimensions.
