You have to scale the imported image to the needed size. Measure a known distance (easy with the graph paper) on the screen with the measuring tool (be sure to have free snap on, so that it doesn't snap to any other objects or image corners), calculate the needed factor to get to the right size and scale the image with modify - scale.
