  You are asking very weird questions.
  What do you mean by "word size"?

      I read in some specs either for 6502 or Z80A the term "memory word size". These are all 8 bit cpus I know that but they have different sized address buses. Rich straightened me out. The term "memory" was throwing me off. I these cases Word Size would be 8 bit. Like todays 64 bit machines. Word size is now considered "64" on 64 bit processors. Although the 6502 had 8 bit registers except maybe for one, and a 16 bit address bus. They are 8 bit "word" sized.
  Under control now. Thanks though.
