Character Counter

Type or paste and this character counter shows the count instantly, then lines it up against the limits that matter: 280 for an X post, 150 for an Instagram bio, 2,200 for an Instagram or TikTok caption, 3,000 for a LinkedIn post, 100 for a YouTube title, 160 for an SMS or a meta description, and more. Each limit gets a bar so you can see how much room is left.

The count is grapheme-aware, which means an emoji or a flag counts as one visible character rather than the several code units it occupies under the hood. Platforms do not all count the same way, so the tool notes that a platform's own counter may differ. It runs entirely in your browser: nothing you type is uploaded, and there is no sign-up.

How to use it

1. Paste or type your post, caption, bio, title, or message.
2. Read the live character count at the top.
3. Find the platform you are posting to in the limit list and check its bar before you publish.

Character limits by platform

These are the limits the tool tracks. Platforms change them occasionally and some count differently near the edge, so treat the last few characters as a buffer, not a target.

Meta title and description limits are guidelines rather than hard caps: search engines cut off by pixel width, not character count, so a title full of wide capital letters may be trimmed earlier than one in lowercase.

• X (Twitter) post: 280 characters, the same for each post in a thread

• Facebook post: 63,206 characters
• YouTube title: 100 characters
• YouTube description: 5,000 characters
• TikTok caption: 2,200 characters
• SMS: 160 characters per message
• Meta title: about 60 characters before search results truncate it
• Meta description: about 160 characters before search results truncate it

Why counters disagree about emoji

A character is not one thing. To you, a single emoji is one symbol. To a computer it may be two, four, or, for a family emoji or a flag, a dozen or more code units joined together. Some platforms count what you see; others count the underlying units; a few apply their own weighting so that emoji cost two characters. That is why the same caption can pass one counter and fail another.

This tool counts graphemes, the visible characters, because that matches how most people think about length. When you are within a handful of characters of a limit and the text contains emoji, accented letters, or non-Latin scripts, check the platform's own counter before posting.
