FAQ
What's 'above the fold'?
The portion of your caption visible before users tap 'more'. Instagram shows ~125 chars, LinkedIn ~150 chars, Facebook ~477 chars.
Does caption length affect reach?
Yes. Platforms like Instagram favor engagement. If your key message is hidden behind 'more', fewer people see it, reducing engagement signals.
Should I always use the maximum length?
No. Optimal length varies by content type. Educational posts can be longer, but punchy/funny posts perform better short. Match length to intent.
