Roof Rafter Span: 14′-0″. Now lets find the minimum allowable rafter size given the above scenario: Therefore given the above example, the minimum allowable rafter size for Hem-fir #3 lumber spanning 14′-0″ is a 2×10 since it can span 14′-5″. A 2×8 member for example cannot be used since it can only span 11-9″.
