# Instagram Character Counter

This Instagram character counter counts the characters, words, lines, hashtags, mentions and emoji in a caption, bio, comment or DM, and checks each Instagram and Facebook text limit. It is for anyone who wants to know a post fits before they share it.

## How to use the Instagram Character Counter

1. Paste or type your caption, bio, comment or DM in the box.

2. Read the counts, then the bars: green is fine, amber is close, red is over the limit.

3. Trim what’s over, then press Copy text and paste it into Instagram or Facebook.

Spaces, punctuation, emoji and line breaks all count toward a character limit.

## How the counter counts

- **Characters** are counted the way you see them. One emoji counts as one, even a flag or a skin-tone emoji built from several parts. Instagram doesn’t publish how it counts emoji, so keep a few characters spare near a limit.
- **Hashtags** are words that start with #. **@mentions** are usernames that start with @.
- **Automated DMs** are measured in bytes, not characters. A plain letter is 1 byte, an accented letter 2, and most emoji 4. A DM full of emoji reaches the limit sooner.

## Instagram Character Counter questions

### How many characters can an Instagram caption have?

2,200, including spaces, emoji and line breaks. Reel captions have the same limit.

### Do emoji count as one character?

In this counter, yes: each emoji you see counts as one. Many emoji are built from several parts, and Instagram doesn’t publish how it counts them, so leave a little room near a limit.

### How long can an automated Instagram DM be?

1,000 bytes. Instagram’s messaging API counts bytes, not characters. A plain letter is 1 byte and most emoji 4, so a DM full of emoji runs out sooner.

### How long can a Facebook post be?

63,206 characters. The feed cuts long posts short, so put the important line first.
