That the sort of range I use in Cylcocross and on the road, @ speed, I have to @ 100rpm to get to "normal" speed. On my 20", I run a 53-39 and it is OK in town with a 11-34 cassette (I prefer 11-28 but Wife needs range).
With a 16" wheel, I would at least try a 56/44 setup, the 56T would be equivalent to a 32T on a 700C bike.
