Facebook enforces strict character limits across posts, ads, page bios, group names, and event titles. This free Facebook character counter tracks your copy live for every field — from the 63,206-character post limit down to the tight 40-character ad headline. Switch between single-field focus and an all-fields view to check your entire campaign in one place.
Facebook allows up to 63,206 characters in a regular post or status update. In practice, posts are truncated in the feed after a few lines and readers must click 'See more', so concise posts (under 500 characters) typically see higher engagement.
Facebook ad primary text has a technical limit of 125 characters before it is truncated on mobile and most placements. You can write more, but only the first 125 characters are guaranteed to be visible without a 'See more' tap.
The headline in a Facebook link ad is limited to 40 characters. This bold text appears directly below the image or video and is one of the first things users read, so keeping it punchy and within the limit is critical.
Standard emoji (e.g., 😊) typically count as 2 characters because they are encoded as Unicode surrogate pairs (using two UTF-16 code units). This counter uses JavaScript's native string .length, which matches how Facebook measures characters — so emojis are counted correctly.
