What is the character limit for Facebook posts?

Facebook allows up to 63,206 characters per post — an enormous ceiling that virtually no one reaches in practice. The real constraint is engagement: studies consistently show that posts between 40 and 80 words perform best in the feed. Longer posts work for storytelling formats but need to earn that length through quality.

Does Facebook cut off long posts?

Yes. Facebook collapses posts longer than a certain threshold (roughly 480 characters in the feed) behind a 'see more' link. This isn't a hard limit — the post still publishes in full — but it means most readers will only see the first paragraph unless you compel them to click. Your opening 1–2 sentences are therefore more important than anything else in the post.

What are the character limits for Facebook ads?

Facebook ad specs vary by format, but in most feed placements: primary text is previewed at approximately 125 characters before being truncated, and headlines are hard-capped at 40 characters. Description fields allow up to 30 characters in some formats. Always check current Facebook Business Manager specs, as these change with platform updates.

How long should a Facebook post be for best engagement?

For maximum engagement on Facebook, aim for 40–80 words (roughly 200–400 characters). Posts in this range are long enough to make a point but short enough to be read in the feed without clicking 'see more'. Exception: storytelling posts and fundraising appeals often perform well at 200–400 words if the content is genuinely compelling from the first sentence.

Is this tool free to use?

Yes, completely free with no login or usage limits. Check as many posts and ad drafts as you need.

Can I use this to check Facebook event descriptions?

Yes. Facebook event descriptions have their own character considerations, and this tool counts characters and words for any text you paste in. Facebook event descriptions support up to 64,000 characters, but well-performing event pages typically use 100–200 words in the description — enough to cover what, when, where, and why someone should attend.

What Is a Facebook Word Counter?

A Facebook word counter is a free online tool that counts characters and words in your Facebook posts, ad copy, and page content in real time. Facebook's post character limit is technically 63,206 characters — far higher than any other major platform. In practice, that limit isn't the constraint; engagement is. Research consistently shows that Facebook posts between 40 and 80 words generate higher engagement than shorter or longer posts. For Facebook ads, the constraints are much tighter: primary text previews are cut after 125 characters in most placements, and ad headlines cap at 40 characters. This tool makes all of those thresholds visible so you can write content optimized not just for the platform's technical limits, but for real audience behavior.

How to Use This Facebook Word Counter

1
Paste your post or ad text
Copy from your document, creative brief, or notes and paste directly into the text area above.
2
Check character and word count
For organic posts, check word count first — aim for 40–80 words for feed posts. For ads, watch the character count against the 125-character primary text preview threshold and the 40-character headline cap.
3
Edit for engagement, not just length
Use the sentence count to identify long sentences that could be split. Shorter sentences perform better in Facebook's feed, especially on mobile where 80% of Facebook users primarily access the platform.
4
Verify your ad headline separately
Facebook ad headlines are capped at 40 characters. Paste your headline here and check it independently from the body copy.
5
Copy and publish or submit to your ad manager
Once your counts are right, copy and paste into Facebook or your ad platform of choice.

Who Uses It & Why

Community Managers and Page Admins

Facebook Pages for brands, local businesses, and organizations post multiple times per week. Community managers use this tool to maintain consistent post lengths — not too short to seem lazy, not so long that the algorithm collapses them behind a 'see more' click. The word counter makes it easy to hit the 40–80 word sweet spot every time.

Facebook Advertisers

Facebook ad copy follows strict limits by placement. Primary text previews at 125 characters in many feed placements. Headlines cap at 40 characters. Writing ad copy that fits these limits without needing platform-side edits saves time and ensures the message lands as intended — not truncated mid-sentence.

Small Business Owners

Small business owners running their own Facebook pages often write posts directly in the composer, with no visibility into word count. This tool gives them a pre-publish check — a way to make sure their post is the right length, reads well, and doesn't get cut off — before it goes live to their audience.

Nonprofit and Advocacy Groups

Facebook remains the dominant platform for community organizing, fundraising, and awareness campaigns. Nonprofits writing appeal posts, event announcements, or fundraiser updates use this tool to keep their messaging tight and compelling — not rambling — within whatever word count serves their specific audience.

Pro Tips

Write for the 'see more' threshold, not the character limit

Facebook's technical limit of 63,206 characters is irrelevant for practical posting. The real constraint is the 'see more' collapse point — roughly 480 characters. If your post is over that, the opening lines must be strong enough to earn the click. If they're not, cut the post down.

Keep ad primary text under 125 characters

In most Facebook feed placements, primary text is truncated at 125 characters. Write your most compelling hook and core offer within that limit. Additional context can follow, but assume most readers will only see the first 125 characters.

Use sentence count to break up dense copy

Facebook users scroll on mobile. Long, dense paragraphs get skipped. Use this tool's sentence count to see if you're averaging over 20 words per sentence — if so, split them. Two medium sentences outperform one long one in the feed.

Front-load value in your opening line

The first 1–2 sentences of a Facebook post are the most read. Put the most interesting, useful, or provocative idea right at the top. Save context, backstory, and supporting details for sentences 3 and beyond.

Check ad headlines and body copy separately

Facebook ad headlines and primary text have different character rules and serve different purposes. Write and check each element separately — headline first (40 chars), then primary text (125 chars visible), then description. Each needs to work independently.
