Crafting the perfect Tweet, optimizing your Instagram posts or brainstorming copy for Facebook ads may all seem like totally different tasks. But they all have one thing in common – they each have a platform-specific character limit. More importantly, you need to know the ideal social media post lengths. This could improve your chances of getting people to read or engage with your posts.
To make it easier, here is a detailed guide on social media character limits and ideal social media post lengths.
Facebook ads character count
Facebook generally has the same character limit across all ad types, with the exception of carousel ads and in-stream video ads.
- Headline – 40 characters
- Body text – 125 characters
- Link descriptions – 30 characters (20 for carousel ads and in-stream video ads)
Facebook posts character count
Facebook is the perfect place to share long-form content, with the platform allowing up to 63,206 characters in regular posts. This gives you ample space to tell a detailed story or explain something in-depth.
Ideal Facebook post length
But just because you can post a lengthy status update on Facebook doesn’t mean you should. In fact, short posts tend to perform better even on Facebook.
According to a BuzzSumo analysis, the ideal Facebook post length is around 50 characters (or fewer), which tends to get the most engagement.
Facebook maximum character limits
Besides posts and ads, Facebook also has character limits for usernames, Page descriptions and comments:
- Username character limit – at least 5 characters and up to 50 characters

Instagram ads character limit
The character limit for Instagram ads is similar to that of Facebook.
- Headline – 40 characters
- Body text – 125 characters

The Instagram caption limit is 2,200 characters. So there’s sufficient space to add context to your posts through your captions. It’s also important to note that Instagram captions are truncated at 125 characters.
Ideal Instagram caption length
While 2,200 characters is abundant caption real estate, huge blocks of text may look messy and distract people from the main focus of the post, i.e., your photo or video. The ideal length is 1-50 characters, as Quintly found that these tend to drive more interactions in an analysis of 5.9 million posts.
