How to append jpg images in graphicsmagick without shrinking the output file?

Question

I have a set of jpg images in a directory, all screenshots of roughly equal width, that I want to combine into a single jpg file. The gm command to do this is:

gm convert *.jpg  -append combined.jpg

However, the output file has extremely small sized images, unsuitable for viewing or printing, unless you magnify them considerably. How can I control that, and simply append the files, keeping their original size? Viewing the files individually, they look fine; but for some reason graphicsmagick is shrinking the images in the convert process.
