Noramally 9.5 inches unless you have a special load on the joist.
To determine the appropriate size of a rolled steel joist (RSJ) for a 19-foot span with purlins on a roof pitched at 45 degrees, factors such as the load requirements, spacing of support beams, and material properties must be considered. Generally, a structural engineer would evaluate these factors and perform detailed calculations to ensure safety and compliance with building regulations. However, for preliminary sizing, an RSJ around 203mm x 102mm x 23kg/m could be considered, but consult a structural engineer for precise specifications tailored to your project.
That really depends upon the load you need to carry and the material that the beam is made of.
