How long should a Facebook caption be?

Facebook is different from other social media platforms in that it lets you go on forever in your captions. To be specific, you get 33,000 characters to make your point on Facebook. For reference, you could post the whole first chapter of Harry Potter and the Sorcerer’s Stone and then some before Facebook would cut you off.

But, let’s face it: most people aren’t on Facebook to read entire novels. On the contrary, in fact. That’s why you want to make your Facebook posts attention-grabbing and delightful but, above all, short. You should stick to a max of 80 characters for organic Facebook posts and between five and 19 words for paid posts. Of course, your mileage may vary, and your audience might prefer slightly more or slightly less.
