What this social media character counter does
This social media character counter checks the length of a post against the character limits of the platform you are writing for. Paste your draft, pick the platform, and see the count, the limit and the room remaining before you publish. It catches over-length posts early, while they are still easy to trim. The check happens before anything is posted.
Post limits worth knowing
The commonly published limits are generous for some platforms and tight for others: X allows 280 characters, Instagram captions allow 2,200, and LinkedIn posts allow 3,000. A message written for one platform often needs shortening for another, so checking the same draft against each destination is a normal part of scheduling a post.
Good to know
The limits shown are commonly published platform limits, and platforms can change them without notice. Free and paid accounts can also be treated differently on some services. If a post that fits here is rejected, the platform's current rules win; shorten the draft and check it again before reposting.
