Facebook caption limit: 63,206 characters · Feed preview truncates after ~477 characters with a 'See more' link. SherpaPost shows the exact cutoff and line breaks before you publish.
A Facebook post preview is a faithful mockup of how a post will render in the Facebook feed before you publish — profile or Page header, body text with the 'See more' truncation at roughly 477 characters, link card unfurl, and reel safe zones. SherpaPost shows the exact cutoff and how line breaks behave, so your hook still works when the rest of the post is collapsed.
Facebook lets you write up to 63,206 characters in a single post — effectively unlimited for normal use. The constraint is the feed: text collapses after about 477 characters behind a 'See more' link, and posts with no media often show even less. SherpaPost previews the collapsed and expanded states so the opening lines do the work.
Meta Business Suite is a scheduler that connects to your Page through the Graph API. SherpaPost is a preview and composition tool — you never grant any permissions, never link an account, and never risk a failed or flagged publish. Draft and polish in SherpaPost, then publish manually from Facebook or Business Suite when you're happy with the preview.
Free to start. No scheduler, no API risk — you stay in control.
