Keep It Short: Why Brevity Is Your Best Friend on Social Media

In a world of endless scrolling and shrinking attention spans, short and sweet is the name of the game on social media. While platforms like Facebook technically let you write a novel (up to 63,206 characters, or about 10,000 words), the data is clear: shorter posts get way more engagement.

Keeping your social media posts short and sweet can dramatically boost your engagement. Posts under 40 characters can get up to 86% more interaction.

It's tempting to share every last detail, but you could actually be hurting your reach. Understanding how people use social media and using a data-driven approach to your content length can make a huge difference.

This guide will break down the research on the best content length for the major social platforms and give you actionable tips for creating concise, engaging posts that will get your audience talking.

The Science of Short

The research is overwhelming: shorter content wins on social media.

What the Facebook Data Says

Major studies have found a striking connection between post length and engagement on Facebook.

A landmark study by Buddy Media in 2011 looked at millions of Facebook posts and found that posts with 80 characters or less got 27% more engagement. What's crazy is that these short posts only made up 19% of all the content published.

For retail brands, the difference was even bigger. Posts under 80 characters got 66% more engagement.

The real sweet spot? Posts under 40 characters, which got a whopping 86% more engagement. But only 5% of retail brands were using this super-short format.

The Psychology Behind It

Why do we love short content so much?

It's Easy on the Brain: Shorter posts are easier to process, so we can consume and react to them more quickly as we scroll.

It's Mobile-Friendly: Most of us are on social media on our phones, where screen space is limited. Short posts just fit better.

We're Skimmers: We scroll through our feeds at lightning speed. Shorter posts are easier to scan and evaluate.

Decision Fatigue Is Real: We see so much content every day. A short, simple post is a welcome break for our tired brains.

Our Shrinking Attention Spans

It's not just you; our attention spans are getting shorter.

A study by the Static Brain Research Institute found that the average human attention span is now 8.25 seconds, down from 12 seconds in 2000. That's shorter than the attention span of a goldfish (9 seconds).

This means you have a very small window to grab someone's attention.

Understanding the psychology of why we prefer short content can help you be more strategic with your social media posts.
