In my past comic the resolution of pages varied from 400x560 to 480x944 pixels. As I'm thinking of using Vector graphics (SVG) for future ones it's important that I pick which aspect-ratio to use. It's common to see 16:9 (720p/1080p) or 16:10 screens now-a-days.
To decide I made this example with several pages/ratios to pick my favorites. As an added bonus I also improved the base Comic page to hide everything while pressing, allowing viewers to hide the side-buttons since those may cover part of wide images.
