Online comics are linear and read mostly by scrolling… When you lay out your comics, do you still think in terms of a traditional printed comic book page and then break up the panels, or are you already thinking for the webcomic format? How do you decide on the shape of the panels, if they’re (vertical) portrait or horizontal(landscape)? What are the pros and cons of each format?

Originally, it's essentially the same thing— taking panel-based comics and arranging them into a long vertical format. But whether it's a page-turning comic or a scroll-to-read vertical format, there are hidden differences. With webtoons in the long vertical scroll format, readers can only focus on one panel at a time. Meanwhile, with a traditional comic, everyone sees the whole page laid out with all its panels at once. That's why the feeling is different. Beyond readers only being able to focus on a single panel, the way white space is divided also becomes something that gives the work its own rhythm. Scrolling down to reveal an image, seeing a speech bubble, seeing text appear as you scroll — it creates a reading rhythm without the reader even realizing it. For example, readers might not consciously notice it, but works aiming for suspense or excitement tend to use tightly-packed white space. Panel design for scroll-format comics works similarly. For me, there's an element of illustration mixed into it— I can use the vertical length as a feature, or bring in montage-style emotional storytelling scenes that are beautifully composed. But overall, I think it comes down to intention in the work. Say a piece is made as a scroll-format webtoon but you want to expand on it by also making a printed volume— in that case, making a printed book also has the advantage that it can be done alongside the webtoon format.
