Facebook Character Limit 2026 – Posts, Bio & Ads
Facebook's post limit is 63,206 characters — so large that almost nobody ever hits it. The number that actually decides whether your post gets read is much smaller: roughly the first 125 characters on mobile, after which Facebook collapses the rest behind a 'See more' link. This guide separates Facebook's hard technical limits from the display limits that determine what people actually see, and covers every other field on the platform: comments, bios, page names, usernames and ad copy.

The Only Facebook Limit That Actually Matters
The 63,206-character post limit is a technical ceiling, not a writing target. Facebook collapses long posts behind a 'See more' link, and the cut happens far earlier than most people expect — around 125 characters on mobile, where the large majority of Facebook browsing happens. Every character after that point only gets read by someone who has already decided to tap.
Key points
- ✓Front-load the point. The first sentence has to work as a standalone hook.
- ✓Put the question, the number or the surprise before the cut, not after it.
- ✓Line breaks count toward the visible space — three short lines can trigger the cut faster than one long one.
- ✓If your post genuinely needs 1,000 words, the link preview or a comment is usually a better container than the post body.
Why the 'See More' Cutoff Is a Range, Not a Number
Facebook has never published an exact truncation point, and it is not a fixed character count. What Facebook is really measuring is rendered height, so the point where your post gets cut depends on several things at once:
- •Screen width — a phone in portrait cuts earlier than a wide desktop feed.
- •Line breaks — each hard return consumes a full line regardless of how few characters are on it.
- •Emoji and accented characters — these render wider than plain Latin text.
- •Whether the post has an attached link preview, image or video above it.
Facebook Ads: Write for the Recommended Length, Not the Maximum
Meta's ad fields accept more text than they display. Ads Manager will warn you when text is likely to be truncated, but it will still let you publish it. The practical guidance is to treat the recommended lengths as real limits:
- •Primary text: about 125 characters before 'See more' appears in most feed placements.
- •Headline: about 40 characters, and noticeably less on right-column and Marketplace placements.
- •Link description: about 30 characters, and it is frequently not shown at all on mobile.
- •Placements vary a lot — always preview your ad in each placement before publishing rather than trusting a single count.
Page Names and Usernames Are Effectively Permanent
A Facebook Page name is limited to 75 characters, and a username (the facebook.com/yourname vanity URL) to 50. Both are worth counting carefully before you commit: Facebook restricts how often either can be changed, and a username change breaks every existing link to your Page. Keep the username short, memorable and matched to your handle on other platforms.
Examples: Good vs. Bad
✅ Hook lands before the cut
“We deleted 40% of our product features last year. Revenue went up 22%. Here is the reasoning we used to decide what to cut, and the three things we got wrong along the way…”
❌ Hook buried after the cut
“Hi everyone, hope you are all having a wonderful week. We wanted to take a moment to share a small update about some changes we have been working on internally over the past several months, which we think you will find interesting…”
Frequently Asked Questions
A Facebook post can technically contain up to 63,206 characters. In practice the limit that matters is the truncation point: Facebook hides everything after roughly the first 125 characters on mobile behind a 'See more' link, so your opening line does almost all of the work.
Roughly 125 characters on mobile and around 480 on desktop, though Facebook measures rendered height rather than an exact character count. Line breaks, emoji, screen width and attached media all shift the cutoff, so treat these as ranges rather than fixed numbers.
Facebook comments are limited to 8,000 characters. That is far more than any comment needs — long comments are also collapsed behind a 'See more' link, so the same front-loading advice applies as with posts.
The profile bio (intro) field is limited to 101 characters. It appears directly under your name on your profile, so it works best as a single short line rather than a list of everything you do.
Yes, spaces count as characters. Emojis typically count as two characters because of how they are encoded, and they also render wider than plain text, which pulls the 'See more' cutoff earlier than the raw character count suggests.
75 characters. Usernames — the facebook.com/yourname part of your URL — are limited to 50 characters and may only contain letters, numbers and periods. Facebook limits how often both can be changed, so choose carefully the first time.
