# Free Threads Character Counter

> Count JavaScript characters, words, and lines in a Threads draft against a 500-character reference limit.

## What the tool does

Check a standard Threads draft with live remaining and over-limit feedback in the browser.

**Direct answer:** This counter reports JavaScript string length, words, and lines against the 500-character standard Threads post reference. Meta separately documents text attachments up to 10,000 characters, but this workbench does not measure attachments or split reply sequences. Use the native composer for the final check.

- Live JavaScript length
- Word and line totals
- 500-character reference check

## How to use it

### 1. Paste the draft

Include the exact text, links, tags, and line breaks you expect to publish.

### 2. Check the standard-post limit

Compare the raw JavaScript length with the 500-character reference.

### 3. Verify in Threads

Use the current composer as the final authority before publishing.

## Threads now has two different text surfaces

Meta's official product material describes a 500-character standard post. It later introduced text attachments of up to 10,000 characters for longer perspectives. Those are not interchangeable: the short post is the timeline entry, while attached text is an expanded reading experience.

Use the 500-character count for the main post you expect people to encounter in the feed. If the argument genuinely needs more room, a concise setup plus a text attachment may be clearer than forcing many disconnected replies.

## Longer writing requires a separate editorial decision

This counter does not create reply sequences or measure the separate text-attachment surface. If a standard post is too long, decide whether to trim it, rewrite it into complete replies, or use Threads' longer-form feature in the native product.

Platform behavior can change after this page is published. Check the visible counter in the current Threads composer before sending, especially for unusual Unicode, links, tags, and new post types.

## Threads text surfaces and their different jobs

The presence of a longer attachment does not turn the timeline post into a 10,000-character field. Plan the feed entry, supporting media, and attached reading experience as separate components.

| Surface | Current documented limit | Best editorial use |
| --- | --- | --- |
| Standard Threads post | 500 characters | A complete timeline thought, question, update, or setup |
| Text attachment | Up to 10,000 characters | A continuous longer perspective or excerpt |
| Reply sequence | 500 characters per standard post | A conversational series whose parts each have context |
| Link in the main post | Count the pasted draft and verify composer | Point to a fuller source without hiding what the reader will find |
| Current composer | Live platform validation | Final check for product and counting changes |

Meta's official 2025 announcement says attachments can hold up to 10,000 characters, but that separate surface is not represented by this counter's single 500-character gauge.

## Choosing between trim, split, and attach

### Short announcement

Trim to one standard post when the date, change, eligibility, and next action can stay together inside 500 characters.

### Step-by-step sequence

Create replies manually when each step benefits from its own example or media; this counter does not split the sequence.

### Essay or newsletter excerpt

Use a concise feed setup plus a text attachment when readers need one uninterrupted argument rather than a chain.

### Cross-platform source

Rewrite for Threads instead of blindly cutting a LinkedIn post; preserve the fact pattern but adjust opening and rhythm.

## Threads draft review checklist

Use the counter to pass the mechanical limit, then make the chosen post surface truthful and complete.
- State the subject and useful premise inside the main post rather than hiding both in a reply.
- Keep qualifications, commercial terms, and source links close to the relevant claim.
- Choose an attachment only when the longer form improves comprehension.
- When creating replies manually, rewrite boundaries and remove repeated setup from later parts.
- Check topics, mentions, media, alt text, and destination links in the current app.
- Confirm the live composer count before publishing because product rules can change.

## Threads length and structure failures

### Treating an attachment as the post body

A 10,000-character attachment is a separate reading surface; the main timeline post still needs a coherent setup.

### Mechanical reply chain

Manual cuts that only respect 500 characters can leave qualifications, links, and examples detached from the claims they support.

### Context hidden at the end

Readers should not need several replies to learn the topic, eligibility, or commercial nature of the post.

### Stale platform assumption

Threads features have changed quickly, so old launch-era limit articles should not replace the current composer and official updates.

## Frequently asked questions

### What is the Threads character limit?

Meta documents up to 500 characters for a standard Threads post.

### Can I post more than 500 characters on Threads?

Meta also offers text attachments of up to 10,000 characters. The main post and attached text are separate surfaces.

### Does this tool publish to Threads?

No. It only counts text locally in your browser.

### Do links count toward the total?

This tool counts the link text you paste. Confirm the final result in the current Threads composer before publishing.

### Does this tool split or measure attachments?

No. It checks the 500-character standard-post reference only. Use Threads itself for reply composition and text attachments.
