Is it a CRJ-600 or -700? You'd be surprised at the difference. The 50-seat -600 model is no fun. It's cramped and uncomfortable; the seats seem smaller.
The 70-seat -700 model is much better. There seems to be more space, and the seats feel a bit larger. It's almost like being in a mainline aircraft (at least, the closest you can get while being on an RJ!)
A little correction... there is no CRJ-600.
The 50-seat CRJ200 has the exact
same fuselage diameter as the CRJ700 or CRJ900. The only visable difference is that the windows have been raised on the CRJ700/900.
The Y seat widths are exactly
the same on all models - 17.2 inches. And the aisle width is exactly
the same on all models - 16 inches.
The cabin height is only 1 inch taller on the CRJ700 and CRJ900 due to the floor being lowered by 1 inch. However, that makes the CRJ700/900 floor width narrower than the 50-seat CRJ200.
