The copying coverage indication device which includes a micro-computer is arranged to indicate the area to be covered by copying according to the sizes of copy paper sheets and copying magnifications for preventing use of copy paper sheets of unnecessarily large or small sizes, and is capable of warning an operator of the necessity for exchanging sizes of copy paper sheets.
