This question already has an answer here:
The aspect ratio of the map frame doesn't match the contents, leaving a lot of white space inside the frame, even after I've scaled the contents to fill one dimension. When I drag one edge of the frame to change the aspect ratio, the scale of the content changes. I know I can zoom with the mouse wheel, but the jumps are too big. Is there a way to set the sensitivity of the zoom? Alternatively is there a better way to change the map's aspect ratio so that the scale doesn't change?
