Methinks you meant to say nominal 6x9 is 2.25" x 3.25"
Oddly, Hasselblad coming from a Swedish company and Rollei coming from a German company, only broadly stated 2.25" and never provided real specifications of the frame size in millimeters. Whether or not any 'medium format' camera ever produced an image area as tall as 57mm is to be disputed until someone takes a metric ruler to a Hasselblad or Rollei negative.
