Why character counts matter
Every platform has its own limits - and they vary dramatically. Bluesky has 300 characters, Facebook 63,206. If you post a 280-character tweet on LinkedIn, you waste reach. If you post a 2,200-character Instagram caption on X, it gets cut off.
Brandlix's cross-posting AI auto-adapts caption lengths per platform. Here you can check manually. Pro tip: the first 125 characters on Instagram are what shows in the feed (the rest is 'see more' tapped) - put your hook there.
