The Facebook character limit
A Facebook post can be up to 63,206 characters — the longest limit of any major network, and the only one on this page that Meta does not publish in its own documentation.
- Meta documents no character limit for a Page or profile post: the Graph API reference describes the message field without a maximum, and the help centre gives no number.
- 63,206 is what the composer has enforced since 2011, when the Facebook engineer who set it explained the number: hex(FACE) is 64,206, minus 1,000 is 63,206.
- Because it is undocumented, treat it as the ceiling rather than a contract — the practical limit for anything anyone reads is far lower.
- The feed folds a post after roughly 477 characters behind a “See more”, and that fold, not the 63,206, is the number worth writing to.
- Links, hashtags and emoji all count in full; Facebook applies no shortening and gives no discount.
Tier differences
Every account and Page
63,206 characters
Personal profiles, Pages and groups all share the same ceiling. Meta Verified changes nothing about post length.
What Meta actually documents
No published limit
The Pages API reference sets the message field to “the text for your post” with no maximum, so any number you read elsewhere — including this one — is observed behaviour, not documentation.
Source ↗What happens if you go over the limit on Facebook
In the app
The composer stops accepting characters at the limit and the Post button stays disabled — text pasted past the cap is dropped.
Through the API
The Graph API rejects the call with an invalid-parameter error on the message field. Nothing is published and nothing is trimmed.
Character limits on every platform
The same post is a different length on every network. This is the full comparison, with the document each number comes from.

Facebook questions
What is the character limit for a Facebook post?
63,206 characters. That is the ceiling the composer has enforced since 2011, and it applies to personal profiles, Pages and groups alike.
Is the 63,206 limit official?
It is enforced, but it is not documented. Meta's Graph API reference describes the message field with no maximum and the help centre gives no number. 63,206 comes from the Facebook engineer who set it, who explained the choice as hex(FACE) — 64,206 — minus 1,000. Treat it as observed behaviour rather than a published contract.
How much of a Facebook post shows before “See more”?
Around 477 characters, after which the feed folds the rest away. That fold, not the 63,206, is the number worth writing to — everything past it is opt-in reading.
Do links and emoji count towards the Facebook limit?
Yes, in full. Facebook applies no shortening and gives no discount: a link costs every character it contains, and an emoji costs what it costs.
