A real capacitor is finite in size. Here we consider a parallel-plate capacitor infinitely large, just to ignore the fringe effect. We actually mean that the plates'' lateral dimensions are much, much larger than the distance, d, between the plates. This is actually true for many practical capacitors. "Large" and "small" are relative.
