Pro tip: paste a real post. The counter follows the rules of the platform you picked, so the number changes even when the text does not.
Every network folds a post at a different point and measures its length by a different rule. The tool applies each platform’s own rules, so what you see here is what your audience sees in the feed.
Try it with your postFeeds hide most of a post behind “more”. The preview and the editor mark the same cut, on phone and on desktop.
Emoji, links and non-Latin scripts cost a different amount on each network. The counter uses each platform’s own rule, so the number here is the number you will see there.
Official caps are shown as fact. Collapse points the platforms never published are marked as approximate.
No account, no AI, no server. Your draft and your image never leave the page.
Five platforms, five rulebooks
These are the numbers the tool applies. Each one traces back to a documented source and carries a confidence level.
