I don't think any computer architectures have used word sizes other than 
a power of 2 multiple of bits in quite a long time, like since the 
1960s.   the DECsystem 10 and 20 were 36 bit word machines.  The PDP8 
was a 12 bit architecture.   there are some low end embedded processors 
that are 4 bit (but thats a power of 2, also) but virtually everything 
resembling general purpose computing equipment in use today is 
8/16/32/64 bits.

note I'm speaking of data size, I know there are numerous 'Harvard' 
architecture (separate code and data space) embedded machines with odd 
instruction word sizes.  Even most of these use 4/8/16 word sizes.
