Make a seamless Instagram carousel where one image runs across every slide

4 slides

How a seamless carousel works in dump

Choose the carousel format when you create a dump and set the slide count. The editor lays out the slides as one artboard, each slide 1080 by 1440, side by side, with a guide at every boundary. Anything you place is placed on the whole strip: a photo can sit across slides two and three, a headline can start on one and end on four. At export, each slide becomes its own file, and an element that crosses a boundary is simply cut at it, so the pieces line up when Instagram shows them edge to edge. The Photos control adds or removes slides at any point; a free account gets up to 5, Creator 10, Studio 20.

What to run across the seams, and what to keep inside them

Run across: the background. A single wide photo, a gradient, a long strip of colour, a panorama. Continuous backgrounds are what make the carousel feel like one object, and they forgive imprecision because nobody checks where a sky was cut. Run across with care: a headline. A word split at a seam is a strong move when the split is clean and the letters are big; a small word cut through its middle just looks broken. Keep inside: faces, products, anything with an edge the viewer will look at. A face on a seam is the one mistake that makes the format look accidental.

A practical pattern: background across everything, one headline across the first two slides, and one contained element per slide from there, each sitting fully inside its cell. The seam guides show exactly where the cuts land, so the contained elements are placed by eye against them.

Slide one is a thumbnail and a promise

Slide one is seen on its own in the feed and on the profile grid, so it has to work as a single post and hint that there is more to the right. The usual trick is to let the crossing element visibly leave the frame: a photo that runs off the right edge, a headline whose last letter is cut, an arrow. A slide one that is complete in itself gets no swipe, however good the rest is.

Grids per slide, not per strip

Each slide in a dump carousel carries its own grid overlay, independently: thirds on slide one, a 3x3 on slide two, nothing on the rest. That matters here because the crossing elements are placed against the whole strip but the contained ones need to be centred within their own slide, and a strip-wide centre line is useless for that. Switch on the overlay for the slide you are working on, place, switch to the next.

Exporting so the order survives

Export gives one image per slide, in order, as PNG or JPG. Upload them in that order and Instagram assembles the strip. A carousel that reads seamlessly at 1080 wide needs each file at that native size, so export with a free account at HD rather than signed out at SD, where the downscale softens the seams. There is no zip; the files arrive one by one, which is also how they go into Instagram. And if a seamless carousel turns out to work better as separate posts, the Separate posts toggle splits the same design into single canvases without rebuilding it.

1. 1
   Create a carousel with the slide count you need

   New dump, carousel, set Photos. Count up if you want a long reveal; the free limit is 5.

2. 2
   Lay the background across the whole strip

   One wide photo or a gradient, stretched over every slide. This is what makes it seamless.

3. 3
   Place the crossing headline against the seam guides

   Big letters, cut cleanly at a boundary, on the first two slides. Check that the split lands between letters, not through one.

4. 4
   Add contained elements per slide with the per-slide grid

   One face, product or line of text per slide, fully inside its cell.

5. 5
   Export at HD and upload in order

   One file per slide, no watermark on any plan. Upload slide one first.
