How are the guides grouped?

Making the carousel: the seamless method, splitting a panorama, taking a panorama and the manual image-editor route.
Sizes and cropping: carousel size, the 3:4 grid cover, puzzle feeds and why a carousel looks blurry.
Content ideas: covers, last slides, captions, alt text, travel sets, photo dumps and collages.
Posting and planning: slide counts, reordering, music, story teasers, feed layouts and a planner without an account.

Which guide answers my problem?

If your seams drift after posting, read why a carousel looks blurry and the one on carousel size. If the first slide looks wrong on your profile, read the 3:4 grid cover guide. If you are stuck on ideas, start with cover ideas or travel photo carousel ideas.

Do the guides need the app?

No. The methods work with any editor that has a canvas and guides, and the image-editor guide shows the manual route. Seamfold is mentioned where it automates a step, such as equal widths or the fold check.
