Social Media Character Counter

X posts (280) and Premium (25,000), Instagram captions (2,200) and bios (150), Facebook posts (63,206), LinkedIn posts (3,000) and headlines (220), TikTok captions (2,200), YouTube titles (100) and descriptions (5,000), Bluesky (300), Threads (500), Pinterest descriptions (500), and Mastodon toots (500).

By Unicode code point, so a single emoji counts as one character even though it uses two UTF-16 units internally. This matches how X and most platforms count. Emoji built from several joined code points, such as some flags or skin-tone variants, can count as more than one.

Yes. Every space, tab, and line break is a character in the count, because each is a code point in your text. Trimming stray blank lines is an easy way to claw back room near a limit.

When your text is over the limit, the tool divides the character count by the limit and rounds up. A 600-character draft against a 280 limit needs 3 posts. Empty text needs 0 posts.

This counter counts every character of a URL. Note that X shortens links to a fixed length in the app, so a long link may take fewer characters there than shown here. Treat the count as a safe upper bound.

Platforms occasionally change limits and some weight certain character ranges differently, for example counting many CJK characters as two. This tool uses a simple, predictable per-code-point count, so confirm in the app when you are right at the edge.

Yes. The Platform and field dropdown lists specific fields, so an Instagram caption (2,200) and an Instagram bio (150) each get their own limit rather than one generic number per app.

Yes. Everything runs in your browser. Nothing you type is uploaded, logged, or stored on a server.

No fixed cap. The count is computed locally, so the practical ceiling is your device memory, and even long drafts update instantly as you edit.
