Facebook Character Counter
Live counts for Facebook posts (63,206), comments (8,000) and the 101-character Intro bio, with the "See more" cutoff at ~477 characters flagged.
How to use the Facebook Character Counter
Type or paste into the field you’re writing
The counter has a separate box for each Facebook field (Post, Comment and Profile intro, or bio) because each has its own limit: 63,206, 8,000 and 101 characters. Paste into the one that matches where your text is going.
Watch the live count against the real limit
The meter updates on every keystroke and counts UTF-16 code units, which is how Facebook measures text. That means an emoji can cost 2 or more, so this count matches what Facebook enforces rather than what a word processor reports.
Keep your hook ahead of the "See more" cut
Only about 477 characters of a post show in the desktop feed before "See more", and roughly 125–150 on mobile. Put the sentence that earns the click inside that window; the note under the Post field keeps both thresholds in view while you write.
Copy your text into Facebook
When the count is where you want it, paste the text into Facebook, or schedule it with JuzPost, whose composer enforces these same limits automatically.
Facebook post character limit: 63,206, but only ~477 show before "See more"
A Facebook post can hold 63,206 characters, and the same cap applies to personal profiles, Pages and group posts. Almost nobody hits it. The number that actually decides whether your post gets read is the truncation point: on desktop, the feed shows roughly 477 characters before collapsing the rest behind "See more". Anything past that line is only read by people who click.
Mobile cuts far earlier and less consistently. As of 2026, device testing puts the mobile cutoff at roughly 125–150 characters. Android lands near 150 fairly reliably, while iPhone varies between about 132 and 150. There is no single official mobile number, so the safe assumption is the low end: if your hook matters, fit it in the first ~125 characters.
Facebook itself shows no character counter anywhere while you type: not in the post composer, not in comments, not in the bio editor. That is the gap this tool fills, a live count against each field’s real limit, with the "See more" thresholds noted so you are writing to the number that matters, not the 63,206 you will never reach.
Facebook bio character limit: Intro (101) vs Page description (155) vs About (255)
Search for "facebook bio character limit" and you will find three different numbers, because Facebook has three different bio fields and most guides conflate them. The personal profile Intro, the short bio under your name, holds 101 characters. A Page’s short description holds 155. A Page’s About (full description) field holds 255, and only about 155 of those display before being cut.
So if the box is only taking about 100 characters, you are editing your personal Intro, and 101 is the real cap. The "255" figure floating around older articles refers to the Page About field, not your profile bio. The counter’s bio field is set to the 101-character Intro limit, the one people most often hit.
Related name fields have their own caps: a profile name allows 50 characters, a Page name 75, and a username must be between 5 and 50. All of these figures were verified against current sources in August 2026.
Facebook ad character limits by placement (safe vs maximum)
Ad fields have two numbers each: what technically fits, and what actually displays. Primary text has no practical hard cap (it shares the 63,206 post limit), but only about 125 characters show on mobile before "See More", and Facebook’s own Feed guidance, current as of 2026, recommends 50–150 characters. Ads Manager will accept copy far longer than the feed will display, which is why text that looked fine in preview turns up truncated in the wild.
The Feed headline technically allows 255 characters, but Facebook’s official recommendation is 27; longer headlines get an ellipsis on many placements. The description field allows 200, shows roughly 25–30 depending on placement, and on some placements is not shown at all, so never put a load-bearing detail there.
Other placements run tighter still: carousel cards allow about 40 characters per headline and 20 per description, Reels ads about 40 for primary text and 55 for the headline, and a Reels overlay ad headline gets just 10 characters, the tightest limit anywhere on the platform. Write to the placement, not to the input field.
Do emojis, spaces and line breaks count? How Facebook actually measures
Facebook counts UTF-16 code units, not what you would intuitively call characters. Spaces, punctuation and line breaks each count as 1, but emojis cost more: 👍 counts as 2, and compound emojis built from multiple code points (skin tones, family sequences like 👨👩👧) can count as 8 or more. This is why a draft that a word processor says is under the limit can still be rejected or cut by Facebook, and why text pasted from a document rarely matches the count you expected.
This counter measures your text the same way Facebook does, in UTF-16 code units, so the number you see here is the number Facebook enforces. The common claim that "every emoji counts as 2 characters" is an oversimplification that undercounts anything with a modifier or a multi-person sequence.
The remaining field limits, all verified in August 2026: comments allow 8,000 characters, Messenger messages 20,000, group descriptions 3,000, group names 75 and event names 64. Reels captions and Stories text have no published hard cap; Stories text is limited by screen space more than by a counter, so treat roughly 100 characters as the practical ceiling. And while the post limit is 63,206, engagement data consistently favours short posts: 40–80 characters is the range that performs best, comfortably inside every "See more" threshold on every device.
Frequently asked questions
What is the Facebook post character limit in 2026?
A Facebook post can contain up to 63,206 characters in 2026, and the limit is the same for personal profiles, Pages and groups. Far fewer are visible without a click: the desktop feed shows about 477 characters before "See more", and mobile shows roughly 125–150. The hard cap is effectively unreachable; the visible window is the number worth writing to.
How many characters before "See more" appears on Facebook?
About 477 characters on the desktop feed, and roughly 125–150 on mobile. The mobile cut is not one fixed number: Android trims fairly consistently near 150 characters, while iPhone varies between about 132 and 150. To be safe on every device, put your key message in the first ~125 characters.
What is the Facebook bio character limit?
The personal profile Intro (bio) holds 101 characters. Pages have two separate fields that often get confused with it: the short description allows 155 characters and the About (full description) field allows 255, of which only about 155 display before being cut. If your bio box stops at around 100 characters, you are editing the personal Intro and 101 is the real limit.
Do emojis count as more than one character on Facebook?
Yes. Facebook counts UTF-16 code units, so a simple emoji like 👍 counts as 2, and compound emojis with skin tones or family sequences can count as 8 or more. This counter measures the same way Facebook does, which is why its number can differ from a word processor’s and why "each emoji = 2" undercounts the complex ones.
What are the Facebook ad character limits?
For Feed ads, Facebook officially recommends 50–150 characters of primary text (about 125 show on mobile before "See More") and a 27-character headline, though the headline technically allows 255. The description field shows roughly 25–30 characters depending on placement and is sometimes hidden entirely. Carousel cards allow about 40 characters per headline and 20 per description, and a Reels overlay ad headline is capped at just 10.
What is the Facebook comment character limit?
Facebook comments are limited to 8,000 characters. That is separate from the 63,206-character post limit and the 20,000-character Messenger message limit. The counter has a dedicated Comment field so long replies are measured against the right cap.
Does Facebook show a character counter while you type?
No. Facebook’s post composer, comment box and bio editor all lack a visible character count, so you only find out you are over a limit when text gets cut or rejected. This tool exists to fill that gap: type or paste here first and you see a live count against the exact limit of the field you are writing for.
