This is the ultimate guide to social media post lengths

Social media post lengths are a hot topic in the social media marketing world.

Not only do you need to keep in mind how long your posts can be, but also how long they should be for maximum engagement.

After all, the right post length can make or break your engagement numbers. A post too small may not be engaging enough, and posts that are too long can make your audience lose interest and drift away.

So with that, this article will act as the definitive guide to social media posts lengths for 2019. We'll discuss how long your posts can be, and give some insights into how long they should be.

We've broken this article down by social network:

Let's check it out.



Facebook is the premier network for most social media marketers, and it's easy to see why. The network has over a billion users and counting, making it the biggest social network on the 'net.

For marketers, this means you can use Facebook to target just about anyone in any city and country worldwide. But all of that is worthless unless your posts and Facebook ads are stuffed with well-written copy.

Your Facebook posts can be this long

Facebook is full of different post types. Some of these include basic Facebook statuses, event posts, ads... and the list goes on.

But don't fret. Facebook keeps the maximum character count the same across most post types.

Currently, your Facebook post can be up to 63,206 characters longYou're not penalized for using images or videos either, so have tons of room to play with.

Here's how long your Facebook should be

But let's be real: no one's going to read a Facebook post that's 63,206 characters long.

More often than not, people are quickly glancing at Facebook on their smartphones. This may be on their train or bus commute, in between classes, or during a lunch break at work.

No one is going to spend their entire commute reading your brand's Facebook novel, so you should focus on keeping your Facebook posts short and sweet.

So how long should your Facebook posts be?

We scoured the 'net for you and found that the general census is that your Facebook posts should be somewhere between 40 and 50 characters.

Facebook expert Jeff Bullas and marketing company HubSpot both found that 40 character is the sweet-spot for Facebook posts.

Bullas took an example from retail brand Wall Posts. They experimented with a number of different post lengths and found that posts between 1 and 40 characters received 86% more engagement than longer posts—pretty sweet, right?


Twitter has had a rough past couple of years, but the company is quickly rebounding as it rights its past wrongs and makes huge feature improvements.

This means that Twitter is quickly becoming more and more important for marketers. So not only do you have to write amazing content on the network, but you need to ensure that it's long enough to get your point across but short enough to be engaging.

Your Twitter posts can be this long

Until 2017, Twitter's post limit was an iconic 140-characters. However, this changed recently when the micro-blogging social network upped its character limit to 280-characters for all Tweets.

Again, images and video don't take away from this limit, so you're free to write great captions for your visual media.

Do note that Twitter DMs (direct messages) can be up to 10,000 characters long. However, this is less of a concern considering DM's are the Twitter equivalent of private messages.

Here's how long your Twitter should be

Just because Twitter upped its character limit doesn't mean you should take advantage of it. Because you'd expect, no one wants to read 280 characters when they're quickly scrolling through their Twitter feed on the bus.

Buddy Media's data shows that tweets between 71 and 100 characters get the most engagement when compared to longer posts. Specifically, these tweets are 17% more likely to be retweeted or otherwise engaged with.

So like with Facebook, keep your tweets short and concise. You'll get the most engagement for your buck.

Unlike other social networks on this list, Instagram is media-centric.

But even though video and images take center stage, you still need to add captions to your media for optimal engagement and to get your message across.

Here's how long your Instagram captions can be—and of course—how long they should be.

Your Instagram captions can be this long

Currently, Instagram captions can be up to 2,200 characters long and can contain up to 30 hashtags in the caption.

Further, you can add another 30 hashtags in the first comment in your post—just make sure the comment is posted shortly after you post your original post.

Social Report users can use the Additional Comment feature in step 3/5 of the post scheduler. This will automatically post your additional comment after your post is published; talk about a time saver!

Here's how long your Instagram captions should be

Obviously, it'll be hard to get someone to read a 2,200 character Instagram caption.

After all, this will require your user to click the 'see more' button, something that's unlikely to happen considering its largely a mobile-only network.

So with that in mind—like the other networks we've covered—keep your Instagram captions short-and-sweet.

The Instagram team recommends keeping your captions under 125 characters. This ensures that your entire caption shows on the Instagram feed.

And while this is shorter than a Tweet, it forces you to make your Instagram captions short and concise. 


LinkedIn is a unique social network.

It's professional-focused, and you can post a ton of different content types. Specifically, you can post statuses, videos with captions, and blog posts.

As you'd expect, statuses and blog posts have different character limits. We'll walk you through both of them below.

Your LinkedIn posts can be this long

Your LinkedIn statuses can be up to 700 characters long company page posts, and 1,300 characters for statuses on individual accounts.

On the other hand, blog posts have no real character limit. However, it's been reported that posts over 120,000 characters will get cut off by LinkedIn's blogging platform.

Here's how long your LinkedIn posts should be

LinkedIn will cut off your posts with a See more button at the 140-character mark. Anything beyond this will be hidden—no matter if your audience is viewing on a desktop or mobile device.

With that in mind, unless you're writing an extremely announcement on LinkedIn, keep your posts under 140 characters for both personal and company posts. This ensures that your readers can view all of your content when scrolling through their feed.

On the LinkedIn blog side, treat it as you would treat any other blog. Make your blog posts long enough to get your point across, but short enough that you keep your audience engaged.

Google My Business


Google My Business is an up-and-coming social network linked to your business' Google Search and Google Maps listing.

You can use Google My Business to update your business' listed hours, address, and even change out the photos. But did you know you can also post status updates to your Google Maps and Search listing?

Yep, it's a thing, and it's super useful.

You can post everything from new product promotions to drink specials to blog post links on your Google My Business page, and they'll be shown to everyone that looks for your business on Google.

Your Google My Business posts can be this long

Earlier this year, Google My Business bumped its character limit from 300 to 1,500 characters.

Additionally, Google removed the 100-character limit from updates, so you can now make your posts as short as you'd like.

Here's how long your Google My Business posts should be

Keep your Google My Business posts as short as possible. 

Posts are extremely small when viewed in a Google Maps or Search. And as you can see in the examples above, your audience can only see the first sentence or so and needs to click on the post to view the rest.

However, Google's design doesn't make it immediately apparent that you can actually click on Google My Business posts, so it's unlikely that most will actually click on your post.

Because of that, we recommend that you try to get your entire point across in the first sentence of your Google My Business post. This will keep everything visible in the preview and gets your point across.

Bottom line

That's all there is to it. In this article, you learned how long your social media posts can and should be on all major social networks. Use these tips to make your brand's social media posts more engaging as you enter the new year.
