Exactly, Ross.  With, for instance, a conveniently chosen 21'4" range, an 8-bit
 resolution will give you a granularity (or step size) of one inch.

I guess what I really meant to ask is "Am I correct in assuming that 8 bits of
 resolution will be more than sufficient?".  It seems to me that, scaled over an
 appropriate range, 8 bits would be appropriate for most hobbyist applications.
