OP, I'm the same height and have the same inseam as your wife, and I ride anything from a 51 to a 54. The calculator at Competitive Cyclist put me at 52 for a French fit so you might be safe assuming that. But I strongly second the suggestion to get her measurements and run them through yourself.
ETA: I mostly ride a 54 and a 53 frame. The 54 is a WSD and feels perfect. The 53 is a Jamis Aurora and even after putting on a shorter stem and adjusting my saddle as far to the front as I can (and still have proper pedaling position) I still feel a bit too stretched out.
