Paste your text once and see it counted against every major platform's limit, the way each platform actually counts. No login, nothing leaves your browser.
Go over a platform's limit and your post can be truncated, rejected, or quietly cut off mid-sentence. This counter checks your text against the current limit on X, LinkedIn, Instagram, TikTok, Threads, Bluesky, and more, all at once. It counts the way each platform counts: X treats every link as 23 characters and most emoji as two, while the rest measure Unicode length. It also shows LinkedIn's “see more” cutoff near 1,300 characters, the point where most readers decide whether to keep going. Paste once, see where you stand everywhere, then fix the platforms you are over before you publish.
Drop your post, caption, or thread into the box. Counting happens instantly in your browser, so nothing is ever sent anywhere.
Each card shows your current count, the platform's limit, and how many characters you have left or how far over you are.
Trim the platforms shown in orange, watch the counts update live, then copy your text and publish with confidence.

Limits reflect each platform's public posting interface and are current as of June 2025. Paid tiers (such as X Premium) and self-hosted servers can raise some limits.
Once your text fits, polish it with the LinkedIn Post Formatter, turn one post into many with the Cross-Platform Repurposer, or measure how it lands with the Engagement Rate Calculator. See them all on the free tools hub.
DemandBird adapts your content for every platform automatically, matching each one's limits, tone, and format, then schedules it all.
