A fan section (22) comprises a fan rotor (42) having a plurality of blades (100) and a spinner (101) positioned forwardly of the fan rotor (42). The fan rotor (42) is driven through a gear reduction (48). The spinner (101) includes a spinner body having an outer surface with a forward end (104) and a rearward end (106). A conical line (108) extends between the forward end (104) to the rear end (106). A first radius (Mc) is measured from a centerline (C) of the spinner (101) at substantially .25 of a length of the spinner (101) to the conical line (108). A second radius (Mp) is also measured at substantially .25 of the length and extends outwardly to the outer surface of the spinner (101). A ratio of the second radius to the first radius is less than or equal to about 2.0.
