The consensus is that the letter + context image should have approximate letterbox (16x9) dimensions, or at least they should not be any "skinnier" than this. This is already implemented on the client side (see this branch), but will need to be re-implemented on the server side (with API modifications, most likely) in order to pre-generate letter images to improve loading performance (see https://github.com/sul-cidr/scriptchart-backend/issues/23).
