Likely you had a very old perf board that was made before the 0.1" spacing
was common.   Back in the vacuum tube days the solder strips had tabs on
3/8" centers and layouts were done on multiples of that.  And then when the
early through hole chips came out they were on 0.1 centers.  And you
couldn't use the 3/16 perf boards.  They likely still make 3/16 boards.
 THey are better for all analog parts where you don't use ICs.

Now days the world has gone "surface mount" and the 0.1 based parts are
looking rather over sized.  Everything is geting smaller and cheaper.
