The image size will vary because of the length of the last callout under the bar, right? 100000 km will stick out past the bar farther than 5000 m. I guess I could eyeball how much based on the font size, number of characters and ouput dpi but, well, bleach. Is there a better way? Plan B is to make my own scalebar but I'm not wild about that idea either.
