I am trying to add images for "cards" (beta) that do NOT get cut off on the edges. I am currently using medium cards. Does anybody know what the aspect ratio/size is for these images? All I can find on the "cards" webpage about them is that they recommend images at least 700 px wide. Note the difference in the images below...the one with black outside row/column labels is the medium "card"--notice that it only displays through L (instead of M) and cuts the row labels off almost completely.
I would also be interested in knowing the other sizes (small and medium), in case I put those to use as well.
