Facebook character counter — the 477-char truncation hiding behind 63,206
Facebook gives you a 63,206-character ceiling for posts — but the feed cuts at 477 characters on desktop, and engagement drops off a cliff after about 80. Paste your post, see the hard limit, the truncation line, and the engagement sweet spot all at once.
Facebook's stated post limit of 63,206 characters is one of the funnier numbers in social media. It's a leftover from a 2011 engineering decision (4× the old 4,096 SMS buffer + padding) and nobody ever hits it. The practical limits are much tighter: the desktop feed truncates at ~477 characters with a "See more" expand, the mobile feed cuts earlier around 240, and engagement peaks at around 40–80 characters. The 155-char Page bio and 101-char personal bio are the tight spots most people actually wrestle with. This counter handles every field Facebook actually uses, with the truncation line shown where it matters.

What counts as one character on Facebook
Letters are easy. Emoji, URLs, hashtags, and line breaks are where platforms disagree. Here is how Facebook counts them.
| Content | Counts as | Note |
|---|---|---|
| Letter, number, space, punctuation | 1 character | — |
| Emoji | 1 character (grapheme) | Facebook counts emoji by grapheme. Modifier sequences count as 1. |
| Hashtag (#example) | Actual length including # | — |
| Mention (@Page) | Actual length — the rendered text counts, not the ID behind it | — |
| URL | Actual length | URLs auto-preview into link cards. The URL text itself still counts, until you remove it from the body after the preview loads. |
| Line break | 1 character | — |
Writing to the Facebook engagement budget
Every major Facebook-engagement study over the last decade lands on the same surprising truth: the shorter, the better. The 63,206-character cap is effectively a myth. Here is where the data actually lands.
Aim for 40–80 characters for highest-engagement posts
Buffer, Hootsuite, and Sprout Social have all landed on 40–80 characters as the peak engagement range across Page post data. That's under a tweet.
Don't go past 240 characters on mobile-first posts
Mobile feed truncates at roughly 240 characters with a "See more" tap. Most Facebook traffic is mobile, so the effective ceiling is a lot lower than the desktop one.
Put the URL in the body, then delete it after preview
Paste the URL, wait for the link-card preview to render, then delete the URL text. The card stays, your body no longer wastes 50+ characters on the URL. This trick saves 20% of the visible post space.
Use the 155-char Page bio for positioning, not hashtags
The Page bio shows directly below the page name on profile and in search previews. Every character counts — no room for stuffed hashtags.
Write the personal bio as a single sentence
101 characters is one short sentence. Trying to fit multiple ideas in forces abbreviation and the line reads like a LinkedIn resume. One idea, one voice.
What people use the Facebook counter for
Facebook-specific workflows from the creators and teams using this tool.
Writing posts that don't trigger "See more"
Mobile Facebook cuts posts at ~240 characters. Posts that fit fully above the cut see substantially higher read-through. Draft in the counter with the truncation line visible.
Polishing the Page bio to 155
The Page bio is shown everywhere your page appears. Write the one-line version of your positioning here and trim it until it fits.
Writing personal profile bios to 101
101 characters goes fast. The counter makes the tradeoff between emoji, CTA, and actual words visible before you commit.
Using the 50,000-char About section for discovery
Facebook indexes the full Page About block. Longer, keyword-rich About content helps Page discovery in Facebook search, and the counter tracks progress against the (generous) 50,000 cap.
Facebook character counter — FAQ
What is the Facebook post character limit in 2026?+
63,206 characters. This is a hard limit dating back to Facebook's early engineering choices and is effectively never hit in practice. The meaningful limits are the truncation cuts — 477 on desktop and ~240 on mobile — where the "See more" expand appears.
What is the Facebook Page bio limit?+
155 characters — Meta raised it from 101 to 155 in 2023 across Pages. Personal profile bios are still capped at 101 characters. The Page description (separate field) is 255 characters, and the About section is effectively unlimited at 50,000.
What is the best Facebook post length for engagement?+
40–80 characters is the repeatedly-measured sweet spot across Hootsuite, Sprout Social, and Buffer's engagement studies. Posts in that range consistently beat longer posts on every Page-level metric. The 63,206 cap is a ceiling, not a strategy.
Do emojis count as 1 or 2 characters on Facebook?+
One, by grapheme. Any emoji — plain smiley, skin-tone, flag, ZWJ sequence — counts as one character on Facebook's compose surface.
Does the URL I paste count toward the character limit?+
Yes — by its actual character length. A common trick: paste the URL, wait a beat for Facebook's link-card preview to render, then delete the URL text from the body. The preview card stays, but the URL no longer eats your visible post space.
How long is the comment character limit?+
8,000 characters per comment. It's the tightest of the active-engagement fields on Facebook, but still plenty for any realistic comment.
