Like any other social media site Facebook has length requirements when it comes to writing on the wall, providing status, messaging and commenting. One line break ( carriage return) is a 'character' consequently, a new paragraph generates two 'characters'. N.B : A space or punctuation is a 'character'. Instagram captions and comments can fetch 2,200 characters. Pinterest pins can have up to 500 characters. Snapchat's caption character limit is 250.
