Carousel post

A carousel post is a single post that holds several photos, slides or videos people swipe through, instead of one picture.

Why it matters when you post for yourself

Instagram's Help Centre says a carousel can hold up to 20 photos and videos, and that the shape you pick for the first one applies to all of them. On LinkedIn the same idea is a document post: LinkedIn Help says you can upload a PDF, Word or PowerPoint file to a post, and people read it page by page.

Carousels suit anything with steps or parts: a process, a checklist, five mistakes, a before and after. Each slide carries one point, so a busy reader takes in one idea at a time, and a useful carousel is the kind of post people save to come back to.

Example

A freelance designer's carousel, 6 slides. 1: "5 things to send a designer before the first call." 2: Your logo files. 3: Three websites you like. 4: Your deadline. 5: Your budget range. 6: "Save this for your next project, or DM me BRIEF for my checklist."

Where it shows up in Postmosis

Common questions

Start my week
How many slides can a carousel have?

Up to 20 photos and videos on Instagram, from its Help Centre. You rarely need all 20: a cover, one point per slide and a last slide with the ask is usually enough.

What size should carousel slides be?

Many people use 1080 by 1350 pixels, a 4:5 portrait. Instagram's Help Centre says photos keep their full resolution from 1.91:1 up to 3:4.

Can I post a carousel on LinkedIn?

Yes, as a document post. Upload a PDF and LinkedIn shows it page by page; LinkedIn Help lists PDF, Word and PowerPoint files up to 300 pages.
