When we were designing circuits for NASA's Chandra X-ray observatory,  
Tye Brady (then at MIT, now at Draper lab) judged that the Viewlogic  
symbols were scaled such that drawing within a B sheet envelope  
yielded the best balance between eyestrain and confusion when  
breaking up a schematic into pages to be published as A sheets. I  
have continued to observe this convention in gEDA.

The gschem library symbols seem to be be very similar to the  
Viewlogic symbols in scale. I doubt this is coincidence ;-)
