For vertebrates, see:
Smith M.W. (1988) J. Mol. Evol 27:45-55
    "Structure of vertebrate genes: a statistical analysis implicating selection"


According to Smith, the average 3'UTR length is 205 nt, with only 5% < 50 nt and  
5% > 1070 nt.


For other taxons, I don't have any idea, but it is likely to be very different.
