What are the most widely comic books formats? Let's say you want to publish online comics across multiple platforms such as Amazon and modern digital platforms. What standards should you use if you don't want to change the format and want to use a single one across several different platforms? By format, I mean image size (800x600) and type (png, jpg).

  • What does "format" mean here? PNG vs JPEG? Traditional grid layout vs infinite scroll?

1 Answer 1


I used a crawler to analyze around 20000 webcomics listed on http://www.thewebcomiclist.com

Disclaimer. Take these results with caution: the crawler made guesses as to what constitutes the main webcomic content instead of, for instance, a website banners. Files of types not strictly meant as image file types were not processed, e.g. PDFs.

In any event, these are the results:

Image size:

       width  height
mean     491     429
std      455     587
25%      100      40
50%      449     238
75%      748     656

File type:

.jpg     46%
.gif     29%
.png     15%
other    10%

Note that there are at least three to four popular aspect ratios (here computed as height over width). From manual inspection on a very small sample size:

  • the larger, e.g. the peak at 1.5 are likely webcomics that have an overarching story;
  • the smaller ones (e.g. the peak around 0.3) are single strips

Density of aspect ratios

Another way to look at aspect ratios is to plot the contours, with a bit of jitter. The axes are in pixels. You can easily identify the long panels with high aspect ratio, the flat and wide panels and the square ones at the intersection with an emergent shape at 600 x 600.

    Can you make a histogram of the size data, or a scatter plot? Because I think averages and standard deviation says very little in this case. It probably clusters around a couple of distinct sizes. A graph of aspect ratio might also be worthwhile.

    Aspect ratio is probably more useful than raw image size, because you want to get a large image size (high DPI) and that will let you scale down if necessary, but it's a lot harder to change the aspect ratio. It's definitely worth seeing what are the standard sizes/ratios, rather than taking an average which might be an awkward compromise.

    While this is an interesting approach, it doesn't give the information OP really needs, for one reason: some sites only support one format. For example, ComiXology seems to only support PDF (yes, not even an image format).

    Instead of averaging, can you tell me what the most common format is?
