Facebook Character Limit (2026 Guide: Posts, Ads, Bio & More)
The Facebook character limit is not one number — it is a system of different limits for different parts of the platform. Posts, comments, ads, bios, page descriptions, and event listings all have their own rules.
If you are a content creator, social media manager, or advertiser, knowing the exact Facebook character limit for each field helps you write content that fits, displays correctly, and performs better in the feed and in search results.
This guide covers every major Facebook character limit in 2026, with separate sections for personal profiles, pages, and — importantly — Facebook Ads, where character limits directly affect ad performance and approval.

Facebook Post Character Limit
The Facebook post character limit is 63,206 characters — which is effectively unlimited for any practical writing purpose.
Despite this generous limit, Facebook’s algorithm does not reward long posts. Research consistently shows that posts between 40 and 80 characters generate the highest organic engagement on personal profiles and pages. Facebook truncates posts after approximately 480 characters in the feed, showing a “See More” link for anything longer.
What this means in practice
- Short posts (40–80 chars) → highest engagement for awareness and reactions
- Medium posts (100–250 chars) → good for storytelling and updates
- Long posts (500+ chars) → best for educational content where depth earns saves and shares
Just because the Facebook character limit for posts is 63,206 does not mean you should use it. Match your length to your goal.
Facebook Comment Character Limit
The Facebook comment character limit is 8,000 characters — plenty of room for detailed replies, support responses, or community engagement.
Comments on posts, photos, videos, and marketplace listings all share this same 8,000-character limit. Unlike posts, comments do not get truncated in the feed, so the full text is visible immediately.
Facebook Profile & Page Character Limits
Personal Profile
| Field | Limit |
|---|---|
| Name | 75 characters |
| Bio (About section) | 101 characters |
| Work & Education entries | 100 characters each |
The personal bio (101 characters) is short — similar to a Twitter bio. Focus on one clear sentence about who you are.
Facebook Pages
| Field | Limit |
|---|---|
| Page Name | 75 characters |
| Short Description | 255 characters |
| Page Category | Pre-set options |
| Website URL | 200 characters |
The short description (255 characters) is what appears in search results and on the page’s cover section. It should include your primary keyword, location (if relevant), and a clear value statement.
Facebook Groups
| Field | Limit |
|---|---|
| Group Name | 75 characters |
| Group Description | 3,000 characters |
| Pinned Post | 63,206 characters |
Facebook Ads Character Limits — Full Breakdown
This is where the Facebook character limit matters most commercially. Facebook Ads have strict display limits that affect how much of your copy is actually visible before the “See More” link appears.
Feed Ads (Most Common)
| Ad Field | Recommended | Maximum |
|---|---|---|
| Primary Text | 125 characters visible | 2,200 total |
| Headline | 40 characters | 40 characters |
| Link Description | 30 characters | 30 characters |
The primary text limit of 125 characters is the most important number in Facebook advertising. This is all that is visible in the feed before Facebook adds a “See More” button — meaning your core message must land within those 125 characters.
Image & Video Ads
- Primary text: 125 characters visible in feed (up to 2,200 total)
- Headline: 40 characters
- Link description: 30 characters
- CTA button: Pre-set options (Shop Now, Learn More, Sign Up, etc.)
Carousel Ads
Each card in a carousel ad has its own limits:
- Headline per card: 40 characters
- Description per card: 20 characters
- Primary text (above carousel): 125 characters visible
With carousel ads, the headline and description for each card are even more restricted. Every word must justify its space.
Collection Ads
- Headline: 25 characters
- Primary text: 90 characters
Story Ads
Stories are vertical, full-screen, and text overlay is limited by what is readable:
- Recommended text overlay: under 90 characters
- Facebook recommends keeping text to less than 20% of the image area
Performance Max / Advantage+ Ads
- Headline: 30 characters
- Description: 90 characters
- Follows similar limits to responsive ad formats
Facebook Event Character Limits
| Field | Limit |
|---|---|
| Event Name | 75 characters |
| Event Description | 64,000 characters |
| Location | 200 characters |
The event description limit (64,000 characters) is enormous, but keep in mind that only the first few lines are visible without clicking “See More.” Write the most important details — date, location, what to bring — in the opening 200 characters.
Why Facebook Ad Character Limits Are Critical
At $7.17 average CPC in competitive niches, every word in your Facebook ad is costing real money. Getting truncated at 125 characters means your core message never delivered.
Key rules for Facebook ad copy:
1. Lead with the benefit in the first 125 characters Do not bury your offer. The most valuable sentence goes first.
2. Use the headline as a second hook The 40-character headline is the last thing most users read before deciding to click. Make it specific and action-oriented.
3. Do not waste the link description 30 characters is not much. Use it for urgency, social proof, or a secondary benefit: “Free shipping. 30-day returns.”
4. Test short vs. long primary text Some audiences respond better to concise 50-character primary text. Others engage more with longer storytelling copy. A/B test both.
How to Check Your Facebook Character Count
Before pasting copy into Facebook Ads Manager or scheduling a post, use a character counter tool to verify your text length.
This is especially important for:
- Ad primary text — knowing exactly when you hit the 125-character visible threshold
- Page descriptions — ensuring your 255 characters communicate maximum value
- Event names — keeping them under 75 characters for clean display
Use the TextCharacterCounter tool to paste your Facebook copy and get an instant count. The SEO and Social Media presets show you the exact limits at a glance.
