Social media word-count: Know your limit

When it comes to writing posts for social, it’s important to know what the word-count is for each of the different social media platforms. That said, ‘less is more’ is often the best mantra to follow. Just because Facebook has a character limit of 63,206 characters, it doesn’t mean that you need to reach that limit in every (or any) post. The key to keeping your audience engaged is often simply to keep your posts short and concise.

There’s an element of usability in this logic. Lengthy posts will get cut off in a user’s feed and they’ll have to click ‘read more’ in order to read your full post. More often than not, people are quickly glancing at social media on their mobile devices and want content that is concise and easy to digest. Obviously, this is dependent on the type of content you are posting, and in some instances lengthy posts are necessary.

Maximum character limits:


Facebook is the busiest social network, and it is also one of the hardest for businesses to gain organic traction with their posts. Facebook expert Jeff Bullas and marketing company HubSpot both found that 40 characters is the ideal character count for Facebook posts.

  • Facebook post character limit: 63,206 characters
  • Facebook username character limit: 50 characters
  • Facebook Page Description: 155 Characters
  • Facebook Comments: 8,000 Characters


Because Instagram is a visual platform, it’s best to keep the captions concise with more of a focus on the visual content. People come to Instagram to look at the images/videos – not to read exceedingly long captions.

  • Instagram caption character limit: 2,200 characters
  • Instagram hashtag limit: 30 hashtags
  • Instagram bio character limit: 150 characters
  • Instagram username character limit: 30 characters
  • On Instagram, you can add up to 30 hashtags whether that’s in the caption of your photo or in the comment section.


For years Twitter used to have a maximum character limit of 140 characters, meaning you couldn’t post lengthy content even if you wanted to. Twitter has now doubled its maximum tweet length, but it’s still not particularly long so many people post in parts if/when a longer diatribe is needed.

  • Maximum Tweet length: 280 characters
  • DMs: 10,000 characters
  • Twitter Handle maximum length: 15 characters
  • Twitter profile name maximum length: 20 characters
