In short
- One long strip per episode, read top to bottom on a phone.
- It is the defining trait of the webtoon; Merriam-Webster's definition says "formatted vertically".
- WEBTOON, Tapas, Lezhin, TOPTOON Plus and most webtoon apps publish in it.
- Manga and western porn comics stay in pages, but several reader apps can show downloaded files as a strip.
What vertical scroll means
In a vertical scroll comic the panels sit in a single column, often with large gaps of empty space between them. The reader controls the pacing with a thumb instead of a page turn. Episodes are short and numerous, which suits per-episode pricing (see pay per chapter).
Webtoons are so closely bound to the format that the dictionary definition of a webtoon includes it. Tapas tells its creators to format series for the scroller setup
, and WEBTOON publishes both its ORIGINALS and its open CANVAS section in vertical scroll.

Where adult comics use it
Korean adult webtoon platforms are vertical by default: Lezhin, TOPTOON Plus and Honeytoon all publish episodic webtoons. Apps that mix formats, such as INKR and MangaToon, carry vertical webtoons next to paged manga; MangaToon's store text promises you can scroll mangas & webtoons smoothly
.
Paged formats still dominate explicit manga and western comics. FAKKU and Irodori Comics sell paged books, and Iron Circus Comics sells DRM-free PDFs.
Reading downloaded files as a strip
If you buy files, a reader app decides how they scroll. Perfect Viewer has a Vertical scroll mode (PDF viewer,webtoon like)
, YACReader offers continuous vertical scroll on iOS and Android, Panels has a vertical mode aimed at manhwa readers, and the self-hosted Kavita server has a webtoon mode. CDisplayEx offers continuous vertical pages in its premium version only.

FAQ
Is manga vertical scroll?
Traditionally no: manga is drawn in pages. Some apps display manga in a continuous scroll, but the panels were laid out for pages.
What app reads vertical scroll comics I downloaded?
Perfect Viewer, YACReader and Panels all have a vertical or webtoon mode, and Kavita has one for self-hosted libraries.
Is vertical scroll better than pages?
On a phone it saves zooming and page turns. On a tablet, or for a two-page spread drawn for print, pages keep the artist's layout.
