thanks to both,
the proposal of jean-luc isn't exactly what is asked since we never need to
instanciate x or y but just need to know about their degrees. The solution
of Ssezi works fine, with the following minor fix:

Max[MapIndexed[If[#==0,0,a (#2[[1]]-1)+b (#2[[2]]]-1)&,CoefficientList[p,
{x,y}],{2}]]

thanks
