The ideal LinkedIn post length (measured on 359,000 posts)

You've been sold a lie: "keep it short on LinkedIn — people don't read." Our data says the opposite.

In short

Across 359,000 LinkedIn posts measured by LinkPost, median engagement increases with post length. Posts with 1,800+ characters have a median of 25 likes and 28 average comments, versus 12 likes for posts under 300 characters. The progression is consistent — each length tier outperforms the one before it.

→ The real rule isn't "write short." It's: write long when you have something to say, and structure it so it actually gets read.

Length, tier by tier

Here are the medians measured across all posts with tracked metrics:

| Post length | Median likes | Average comments | |---|---|---| | Under 300 characters | 12 | 14 | | 300 to 700 | 17 | 20 | | 700 to 1,200 | 19 | 25 | | 1,200 to 1,800 | 21 | 27 | | 1,800 and above | 25 | 28 |

Median engagement doubles between the shortest and longest posts. And it's not just likes — longer posts also collect more comments, the engagement signal LinkedIn weights most heavily.

Reading note: these are medians, not averages. Very short posts can show a flattering average because of a few breakout hits, but the median stays low. The median describes your "typical" post, not the exception.

Why long wins

Our study on 438,413 posts confirms the pattern at larger scale: posts of 1,500 characters and above average +49% engagement compared to posts under 300 characters.

The reason comes down to two words: dwell time. How long a reader spends on your post is one of the most powerful signals in LinkedIn's relevance model. A 200-character post can only capture a few seconds. A long, well-paced post keeps the reader engaged, accumulates dwell time, and generates more reactions per impression. That signal then amplifies distribution.

This is also why post format matters so much — carousels, for instance, naturally extend reading time by design.

Long doesn't mean bloated

The trap is confusing "long" with "padded." A 1,800-character post that circles the same point performs worse than a tight 800-character post that's dense and useful.

What makes a long post hold attention all the way through:

→ A hook that creates expectation within the first 200 characters — the threshold before the "see more" cut → One idea per paragraph, short sentences, breathing room between blocks → A concrete data point or example to anchor the argument → A payoff at the end that delivers on the hook's promise

Before you publish, you can check these signals automatically with LinkPost's free post analyzer — it scores your draft on 300+ factors and pinpoints exactly where you're losing attention.

What to take away

• Don't compress for the sake of it. Short isn't rewarded — it's just faster to write.
• Aim for density, not raw length: every sentence needs to earn its place.
• If you're choosing between 250 and 1,200 characters for the same idea, go with 1,200 — as long as you can hold attention the whole way.
