Social post character counter and length checker
Different publishing surfaces impose different text limits, and those limits can change as products evolve. This tool gives writers a fast pre-publish count for the standard X post, the longer X Premium post format and a LinkedIn post, while keeping the numeric limit editable.
What is counted
The character count uses Unicode code points rather than JavaScript's raw UTF-16 code units, which makes ordinary emoji counting more intuitive. Platform-specific counting can still differ for links, combined emoji sequences and other special content, so the platform's own composer remains the final authority.
Use the custom limit for campaign rules
Choose Custom when an ad field, scheduler, internal editorial policy or another social network uses a different maximum. The remaining-character and percentage indicators update as you type.
Length is not the same as performance
Staying under a technical limit does not make a post effective. Message clarity, audience relevance, opening context, visual assets, link treatment and accessibility still matter.
