The minimum size of hanger rods for a pipe diameter of 5-8 inches depends on factors such as the weight of the pipe and the material of the rod.
A common rule of thumb is to use a hanger rod that is one size larger than the pipe diameter.
For example, for a 5-inch diameter pipe, a 6-inch hanger rod would be suitable.
