So I've posted a few images on here, and I've had trouble figuring out the correct size for images. For example, I've made a comic that has 3 pages so far, but the 3rd page appears to show up smaller than the first 2 pages.

For comparison, Page 2 of my comic (hypnohub.net/post/show/39762?pool_id=1509 )
is 1900 x 2700 while
Page 3 (hypnohub.net/post/show/42458?pool_id=1509) is 2000 x 3400

I'm not sure if the third page is too big or whatever, but I've never really figured out how that works, so any advice is appreciated!

I apologize in advance if I needed to ask this question on a specific thread; I looked around but didn't manage to find any relevant threads. Please lock it if that's the case and I'll post this on the correct thread.

I'm not exactly sure what you're asking - do you want to know how I determine the resolution I use to post my art, or are you asking how to keep your comic pages consistent size?

Oh sorry, I meant determining the resolution you use to post art.

Generally, it depends on the level of detail. Higher quality pics with more polish and details I save at something like 1920px, simpler but finished works at about 1600px, and rougher/sketch work about 1200px. I generally don't like going lower than 1200px because I like people being able to zoom in up close, and I don't go higher than 1920px to keep the filesize from getting too large.

That makes sense. Thanks!
