How to post a longer carousel on X

Four pictures is the limit for one post. For eight or twelve slides, post them as a thread: the first four with your hook, then reply to your own post with the next four, and so on. Number the slides so people can follow along, and end the last post with what you want them to do.

Usually it’s better to cut. Four strong slides beat twelve on X, where people scroll fast. aiCarousels writes up to 4 slides when you pick X, so the carousel fits one post.

How to make the slides for an X carousel

On X the text is short, so the slides do the work. aiCarousels writes and designs them from one line, sized for X, with the post text written to fit 280 characters.

1. Type your idea and choose X On Home, write what the carousel is about and set where you’ll post it to X. Pick a writer, or leave it on Auto: Felix is the one made for X and Threads, short and sharp.
2. Check the slides and the text Change any word by clicking it. Switch to Caption for the post text written from your slides, with a counter for X’s 280 characters.
3. Download and post Click Download PNGs for a picture of every slide, numbered in order, then post them as above.

Tips for an X carousel people open

1. Make the cover readable in the grid. In the feed each picture is small and cropped. Big words, near the middle.
2. One point per slide. Four slides, four points, nothing else.
3. Put the hook in the text, not only on the slide. The first line is what people read before they tap.
4. Use the same slides elsewhere. 4:5 slides also post on LinkedIn, Instagram and Threads. See carousel sizes for every platform.
5. Bold one word. X has no bold button, but the free X text formatter does it.
