I'd like to share some tips in making your comic in the Vertical Scrolling format.
I'm not going to teach you anything about how to make a comic, I'm far from being the one to do that ;), and I'm not against the traditional comic layout page, I used to make my comic in that format some time ago. And I love both formats, I'm not saying one is better than the other… just to be clear.



That's some stuff that could help you make your webcomic more interesting in this format.
But what's about the technical stuff?
Ok, I make my comic in a very traditional way, here's the sketch of the first part of chapter 8:
First, the sketch. I use a very large canvas to work and place the most of the chapter, 800px width x 30,000 - 50,000px height.


You see that I put a lot of notes and stuff so I can remeber some of the ideas I have in mind. Then I add inks, tones and textures and the final stage is to add speech bubbles, text and SFX.
When the file is ready, I split it into pieces (normally a mobile screen is 800px x 1280px). I use this site to do that. It's free and you could adjust some settings to get a better quality. The final file size may vary (180 - 300MB), so you need to adjust some stuff to fit the restriction of 20MB that The Duck have. Once you convert your file to .jpg, it needs to be under 20MB.
This way, you can upload your files without any trouble.
Well, this is some tips and I'm sure that there are a lot more and different ways to get the things done, so, I hope you like this tutorial and please, feel free to ask anything or share your own experience making this type of format.
You can read my comic here in DrunkDuck and here in Webtoons
