Facebook Character Limit: Every Field
The current limits, where your text actually gets cut off, and a free tool to check your draft.
The short answer
Facebook has the most generous post limit of any major platform: 63,206 characters — an oddly specific number that a Facebook engineer once confirmed was chosen as an in-joke (63,206 reads as 'more than enough'). Comments allow 8,000 characters.
In practice the cap is irrelevant; the fold is everything. Facebook truncates feed posts at roughly 477 characters behind 'See more', and engagement data has long favored much shorter posts — the most-shared posts tend to be under 80 characters. The 63,206-character ceiling exists so you never have to think about it; the 477-character fold is the real limit.

Writing effectively within the limit
Write Facebook posts backwards from the fold: one idea in the first sentence, one reason to care in the second, and stop. If you need 2,000 characters, you probably need a link post or a note-style image instead. Use a character counter to keep drafts under 477 - and under 80 when you want maximum shareability.
