How to make a seamless carousel on Instagram

Key takeaways

• A seamless carousel is one wide picture cut into equal slides; the edges match because every slide comes from the same picture at the same scale.
• Three 4:5 slides need a picture 3240 × 1350 pixels. A smaller one is enlarged and goes soft.
• Keep faces and words off the cut lines, and let a line or a shape cross each one on purpose.
• Every slide must be the same shape, and the slides must be added in order.

What is a seamless carousel?

A seamless carousel is one wide picture cut into slides, so that the image carries on across each swipe with no visible join. It’s also called a panorama carousel. Instead of five separate pictures, the viewer gets one scene that unrolls as they move through it.

It works for a simple reason. On an ordinary carousel a viewer has to decide to swipe. On a seamless one, half an object is already showing at the edge of the frame, and the swipe finishes a picture they’ve started looking at.

There are two ways to use it. The plain one is a single wide photograph: a landscape, a room, a product line-up. The designed one is a set of slides, each with its own words, tied together by a shape, a line or a picture that runs from one slide into the next. This guide covers both.

How does the cut work?

Lay the slides side by side and they make one long strip. Three portrait slides of 1080 × 1350 pixels make a strip 3240 pixels wide and 1350 tall. The wide picture is placed across that whole strip, and each slide is cut from its own third.

Because every slide comes from one picture at one scale, the edges match exactly: the last column of pixels on slide one is the neighbour of the first column on slide two. That’s all “seamless” means. There’s no blending involved, only arithmetic.

So the only real question is how big the picture needs to be:

A picture smaller than the strip still works, but it has to be enlarged to fill it, which softens it. A picture of a different shape is cropped: it’s scaled until it covers the strip, centred, and whatever hangs over the long edges is lost.

Cut your own

Choose a wide picture, set the number of slides and their shape, and check where the cuts fall before you download. The slides come as numbered JPEGs in a ZIP. Nothing is uploaded: the picture is cut in your browser.

For 3 slides at this shape, a picture of 3240 × 1350 px fits exactly. Nothing is uploaded.

When you post, add the slides in number order. If they go in out of order, the picture is scrambled.

Which shape should the slides be?

Portrait, 4:5, unless you have a reason. A portrait slide takes up more of the screen than a square one, so each part of the panorama is shown larger.

Square still suits a very wide scene. A five-slide square strip is five times as wide as it is tall, which fits a true panorama better than a portrait strip does. With portrait slides and a shallow photograph, the picture is scaled up to fill the height and both of its ends are cropped off.

Whatever you choose, every slide in the post has to be the same shape. That’s what makes a strip possible, and it’s Instagram’s rule as well: “You can’t select a different orientation for each photo or video” (Instagram Help Center). A carousel can hold up to 20 slides; a panorama rarely needs more than five.

What makes a seamless carousel look good?

Where the cuts fall. A seamless carousel is judged at its joins, so plan them.

Keep faces off the cut lines. A face split between two slides looks like an accident on both. Move the cut, change the number of slides, or reframe the picture until faces sit inside a slide.

Keep words off them too. Text that straddles a join is unreadable on both slides. If a headline runs wide, give it a slide to itself.

Let something cross every cut on purpose. A horizon, a table edge, a road, a shelf, a wall. The eye follows a continuous line, and following it means swiping.

Give each slide a subject. Viewers see one slide at a time. A slide that’s nothing but the empty middle of a landscape is a dead frame, and it’s where people stop.

Make the first slide work alone. In the feed and on your profile it’s the only one showing. It needs a subject and a visible sign that the picture continues past the right-hand edge.

How do you design one with words on it?

This is the more useful kind for most accounts: a normal carousel with a hook, some points and a close, where something visual ties the slides together.

Design it as one wide canvas, not as separate slides. Set up a canvas as wide as all the slides together, draw guides at each cut, and lay the whole thing out at once. Then:

• Keep each slide’s words inside its own guides, with a margin on both sides. Text is the one thing that must never cross.
• Run a shape across the joins. A band of colour, a curve, a row of dots, an arrow that starts on one slide and lands on the next.
• Split a picture across two slides where it suits the story: a product half on one slide and half on the next pulls the viewer across.
• Carry the background through. One gradient or one texture across the whole strip makes the set read as a single piece.

Then cut the canvas into slides, which is what the tool above does.

RapidCreate’s Post Studio builds carousels this way. Its templates draw their shapes across the whole post and split a picture over the join between two slides, so the continuity is part of the design and never something to line up by hand.

Which mistakes come up most?

• Posting the slides out of order. Number them, and add them in that order.
• A picture that’s too small. It gets enlarged and goes soft. Check the size table before you start.
• A face or a word on a cut. Preview the joins first.
• Mixing shapes. One square slide in a portrait set breaks the strip.
• Empty slides. Every slide needs something to look at.
• No cue on the first slide. If nothing runs off the right-hand edge, nobody knows to swipe.

Questions

What is a seamless carousel?

One wide picture cut into several slides, so the image continues across each swipe without a visible join. It is also called a panorama carousel.

What size picture do I need for a seamless carousel?

As wide as all the slides together. For 4:5 slides that is 2160 × 1350 pixels for two, 3240 × 1350 for three and 5400 × 1350 for five. For square slides the height is 1080.

How do I split a picture for an Instagram carousel?

Choose the number of slides and their shape, scale the picture to fill the whole strip, and cut it into equal parts 1080 pixels wide. The splitter on this page does it in your browser and numbers the slides.

Can a seamless carousel have text on it?

Yes. Design it as one wide canvas with a guide at each cut, keep each slide’s words inside its own guides, and let shapes and pictures run across the joins.
