Why does Facebook have this character limit?

Facebook's 63,206 character cap dates from a 2011 internal API limit that has never been reduced. The platform supports long-form content, but its News Feed algorithm aggressively favors short, scannable posts. Mobile devices truncate the feed at roughly two visible lines (~80 characters) before showing 'see more.' Anything past that requires a tap to expand — and most users don't tap.

Tips for Writing Better Facebook Content

1Aim for 40–80 characters for maximum engagement

BuzzSumo's multi-million-post analysis showed posts under 80 characters get 66% more interaction than longer ones. Brevity wins.

2Long posts are still valuable for storytelling

If you're using Facebook for personal essays or business storytelling, the long-form limit is your friend. Front-load the hook above the 'see more' fold.

3Comments cap at 8,000 characters

Far below the post limit but still spacious. Use the room for substantive replies that drive thread engagement.

4Pages: optimize page name and short description

Page names are capped at 75 characters and appear in Facebook search. The 255-character page description appears in Google search results.

5Lead with a question or surprising statistic

Facebook's algorithm rewards interaction velocity. Posts that drive comments in the first 30 minutes get amplified to wider audiences.
