Turn a 1,200-Word LinkedIn Post Into 10 Swipeable Carousel Slides

The carousel I posted in March hit 412,000 impressions in 48 hours. The exact same content, formatted as a text post the week before, hit 4,200. Same words. Same audience. The only difference was the format — 10 swipeable slides instead of a wall of text.

That gap is not a fluke. The LinkedIn feed is a thumb-stop contest. Text posts demand 30 seconds of attention before you get to the payoff; a carousel gives you 2 seconds per slide. People who would have scrolled past your opening sentence will tap through ten images of a checklist. This is the whole reason carousel (a.k.a. LinkedIn document post — a multi-page PDF users swipe through in-feed) hit the front page of every marketing blog in 2024.

The catch: most people write the post first and then try to cram it into slides. That gives you 14 slides of 90 words each, which is just a text post with extra steps. The right way is to decide on 10 slides up front, then cut the 1,200-word post into chunks that fit — about 80 to 120 words per slide, with one idea per slide, and a visual hierarchy that survives being skimmed on a phone.

Here's the workflow I now use every time.

1. Decide the slide count before you write the post

Ten is the sweet spot for two reasons. First, LinkedIn shows the slide counter ("1/10, 2/10...") above each page, and the visible progress bar is a built-in completion motivator — readers keep swiping because they want to see all 10. Second, 10 is the maximum the LinkedIn PDF uploader accepts in a single document post, so you never have to think about whether to add an 11th.

If your post only has 6 strong ideas, ship 6 slides. Padding to 10 is the fastest way to lose the reader. But if you've already drafted 1,200 words, almost any topic can support 10. The number is the constraint that forces editing.

2. Strip the post down to its spine

A 1,200-word LinkedIn text post has a lot of fat. The classic structure is a hook, a personal story, three to five teaching points, an example, and a call to action (CTA, 行动号召 — what you want the reader to do next, like "comment below" or "DM me for the template"). For a carousel, that gets compressed. The story usually goes in your caption (the post text that appears under the PDF), not on the slides. The CTA almost always lives on the last slide.

The chunking exercise looks like this:

1. Copy your 1,200-word draft into a fresh document.
2. Read it once and circle every "idea boundary" — places where the topic shifts.
3. You should end up with 8 to 14 circled ideas. Aim for 10.
4. If you have 14, merge the two weakest. If you have 6, split the longest one in half using a before/after or "common mistake" frame.

A real example from a recent post I shipped: the original draft had a 240-word section on "why most B2B (Business-to-Business, 企业对企业) cold emails fail." I split that into two slides — "3 reasons cold emails fail" and "Why the third one isn't your fault" — because the third reason was a contrarian point worth its own beat.

3. Pick a slide template before you start writing the slides

This is the step that saves the most time and the one I see skipped most often. You should not be making design decisions for every slide. Pick a 10-slide template in Canva, Figma, or PowerPoint before you write a single line of slide copy. Three rules for the template:

• One layout per content type, not per slide. Use the same layout for all your "list" slides, the same layout for your "big quote" slides, and a different one for your cover and CTA. Carousels look professional when the layout pattern is consistent; they look amateur when every slide is bespoke.
• Use a 1:1 square canvas (1080 × 1080 px) or 4:5 portrait (1080 × 1350 px). Square is safer for mobile; 4:5 takes more vertical space in the feed and stops the thumb better. Don't use 16:9 — that letterboxes on phones and looks small.
• Two fonts, max. One for headlines, one for body. I default to a clean sans-serif (Inter, Söhne, or IBM Plex Sans) and use weight and size to build hierarchy. Carousels with five fonts look like 2014 infographics.

You can build the template in about 20 minutes in Canva using a free LinkedIn carousel template, or in 45 minutes in Figma if you want pixel-perfect control. Do this once, save the file as your "carousel base," and reuse it for every future carousel.

4. Write the slides in this exact order

People often write slides in the order they'll appear, which is a mistake. The cover slide is the hardest one to write but the most important — it determines whether anyone swipes at all. Write the cover last, after you know what the rest of the carousel is actually about.

The order that works:

1. Slides 2-9 (the meat). Write these first. For each "idea" you circled in step 2, decide whether it becomes a list slide, a single-point slide, or a quote slide. Most teaching points are list slides (3-5 short items, one per line). One slide per post should be a "contrarian point" or a "this is the mistake" slide — these get the most saves.
2. Slide 10 (the CTA). Write this second. The CTA should match the goal of the post. "Save this for later" is generic and rarely works. "Comment your biggest struggle with X" is better because it triggers LinkedIn's algorithm (Engagement, 互动 — likes, comments, saves, shares that signal a post is worth showing to more people) to push the post further. "DM me 'X' for the template" is best if you have something to give away, because it builds a sales conversation.
3. Slide 1 (the cover). Write this last. The cover is a short, punchy promise of what the reader will get. "10 LinkedIn hooks that will 3x your reach" beats "How to write better LinkedIn hooks." Use a number, a verb, and a concrete payoff. A common structure is: [Number] [things] that [outcome] — in [timeframe or constraint].

The whole writing pass takes 30 to 60 minutes if your template is already built and your source post is solid.

5. Cut 30% before you export

This is the editing pass most people skip. A 1,200-word post becomes about 900 to 1,000 words in slide form — even though there are 10 slides, each holds 80-120 words. The cut is what makes the carousel feel tight.

Three things to cut first:

• The intro sentence on every slide. "Here are three reasons cold emails fail:" wastes the first line of your slide and tells the reader what they're already looking at.
• Hedge words. "I think," "in my experience," "it's possible that" — these are the verbal padding of a 1,200-word essay. Slides are declarative. State the claim.
• Explanations that belong in the caption. If a slide needs three sentences of context to make sense, the context goes in your LinkedIn caption (the post text under the PDF), not the slide itself. Slides reward brevity; the caption rewards depth.

You should be able to read each slide in 5-7 seconds. If you can't, it's too dense.

6. Export and post

Export the final document as a PDF (not a PNG image carousel — those don't track the same in the LinkedIn feed, and they won't give you the swipe counter that drives completion). File size under 50MB, which is the platform's limit.

When you post:

• The caption should be 80-150 words, not the full 1,200. Use the caption to set up the carousel, drop a personal story, and end with the CTA. The carousel does the teaching.
• The first comment is wasted real estate. Most creators use the first comment to repeat the CTA or post a "thanks for reading" note. Don't. Use the caption for that.
• Post between 8-10am in your audience's timezone, Tuesday through Thursday. Engagement compounds in the first 90 minutes; if a post flops in the first hour, the algorithm rarely gives it a second chance. The above window catches the morning commute in the US and the late-afternoon in Europe.
• Pin a follow-up text post 24-48 hours later that rephrases one of the carousel's points and links back to the original. Carousels drive reach; text posts drive conversation. You want both.

The bit nobody tells you

The mistake I see most often is treating the carousel as a redesign of the text post. It isn't. It's a different format with different rules. A 1,200-word essay and a 10-slide carousel are two pieces of content that share a topic, not one piece of content in two shapes.

If you write the post first, then "convert" it to slides, you'll end up with too much text and not enough visual hierarchy. If you reverse it — pick the slide count, build the template, then write the slides — the same 1,200 words will reach 10x as many people, with less writing time, not more.

The post I opened with took 90 minutes from draft to publish. The text version took the same. The difference was the format, not the effort.
