The spinner size is really dictated by the cowling. The spinner backplate should be the same or very slightly smaller than the front of the cowl to make it look realistic.

Of course, if there is no cowl, then it becomes uncritical. Use whatever size looks good to you!

I asked around, most people on our field are using 2 1/4 inch ones.  Must be an availability thing.
