Facebook's character limits are the most generous of any major social platform — posts technically allow up to 63,206 characters (as of June 2026) — but that number is largely academic. In practice, only the first 477 characters are visible in the News Feed before a See More link collapses the rest. On mobile the visible window is even tighter, around 125 characters. This Facebook Character Counter shows your exact character count as you type, so you can craft the critical above-the-fold portion of your post with precision and write longer supporting content with confidence that it will not be cut mid-sentence. Paste or type your text to see the count instantly — no account, no installation, runs entirely in your browser.
Beyond the post itself, Facebook enforces separate limits across every field on the platform. Comments are capped at 8,000 characters — long enough for a thorough reply but still finite, so very long comment threads can get cut off if a single comment pushes the boundary. Your personal profile bio sits at a tight 101 characters, roughly one sentence, which demands the same brevity discipline as a Twitter/X bio. Facebook Pages have a separate About/description field limited to 255 characters; that text surfaces in Google search results for your Page, so every character should earn its place. Group descriptions and event descriptions each carry their own separate limits that differ from personal post limits — if you run community spaces on Facebook, test your copy in this counter before submitting to avoid silent truncation.
One important technical difference: Facebook counts each emoji as a single character, unlike Twitter/X which counts each emoji as two UTF-16 units. That means a post with ten emoji on Facebook consumes only 10 additional characters, not 20. Spaces, line breaks, hashtags, and @mentions each count as one character toward the limit. If you are repurposing copy from Twitter to Facebook, your character count will look slightly different due to this emoji-handling difference — paste the text here to get the accurate Facebook count rather than estimating from a Twitter-oriented tool. The stats panel on the right also shows word count, paragraph count, and reading time so you can evaluate the full shape of your post at a glance.
