Main Question or Discussion Point

When an object is moved away from a plane mirror, its size decrease when seen in the mirror. But, when we draw image on paper for an object in different positions in a plane mirror, the size of the image doesn't seem to change. Why? Will the size change or not?

The size of the image doesn't change, but it looks smaller since it is farther away.

The image in a (plane) mirror will appear to be the same distance behind the mirror as the object is in front of the mirror. Stand near a mirror and look at a distant object and then at its image. They will appear pretty much the same size.
Stand by the same object and look at its image in the same mirror and the image will look much smaller than the object.
Size and (apparent) distance 'go together'.
