I have been told that Cisco has many customers who have large OSPF networks
with as many as 50 routers per area. (50 is the number Cisco uses as a
recommended max. Of course the real answer is "it depends," as others have
said.)
You might want to take a look at the OSPF section in Cisco's "Designing
Large-Scale IP Internetworks" document if you haven't already.
