Threads Expands to 10,000 Characters: A New Era for Long-Form Sharing

Meta’s Threads, originally designed as a micro-posting app to rival X (formerly Twitter), has just rolled out a feature that could reshape its identity. Starting September 2025, users can attach up to 10,000 characters of additional text to their posts.

The move opens the door to long-form publishing inside Threads, blurring the line between social micro-updates and blogging. Instead of restricting users to brief updates, the platform now offers an integrated writing space with formatting and linking capabilities.

Why Threads Introduced Longer Posts

Threads previously limited updates to 500 characters, forcing creators and users to rely on awkward workarounds such as posting multiple connected updates (“threads”) or uploading screenshots of text from newsletters, books, or podcasts.

Meta recognized this gap. By introducing long-form attachments, Threads aims to:

• Provide an official alternative to text screenshots (which algorithms cannot read).

• Help creators and journalists share deeper perspectives directly within the app.

• Encourage users to stay engaged longer on Threads, while still allowing outbound links to external work.

In a statement, Meta emphasized that this update is about giving people more space to share meaningful content, not just quick reactions.

How the 10K Character Feature Works

Adding extended text is simple. When composing a post, users will now see a new attachment icon within the composer. Clicking it opens a blog-style editor, where they can draft, format, and publish their longer piece.

Once posted, the extended text appears under the original update with a “Read more” prompt, allowing readers to expand it seamlessly within Threads.

Formatting and Presentation Options

Threads’ new editor supports several basic formatting tools that make long-form writing more accessible:

• Bold text for emphasis.

• Italics for highlights or quotes.

• Underlining and strikethrough for stylistic variation.

• Support for embedded links that appear prominently in both the short post and the long-form attachment.

This ensures creators can craft professional, readable posts that stand apart from plain-text updates.

Threads vs. X: How They Compare

X (formerly Twitter) already offers long-form content for premium subscribers, with posts extending up to 25,000 characters. However, Threads’ approach stands out in key ways:

• Free access: Unlike X, which requires payment for long-form publishing, Threads gives all users the ability to post extended content at no cost.

• Link-friendly: External links are allowed and highlighted, making it easier to promote blogs, newsletters, and podcasts.

• Creator-centric: The formatting tools resemble entry-level blogging rather than simple text expansion.

The trade-off is that Threads’ extended posts are not yet searchable via Google and are not federated to other decentralized platforms such as Mastodon. Still, Meta has hinted that federation could come in the future.

Potential Benefits for Creators

This update has clear implications for creators, businesses, and thought leaders:

• Journalists and authors can now share excerpts from books or articles without resorting to screenshots.

• Newsletter writers and podcasters can promote their work directly on the platform, linking to their main site or subscription page.

• Community builders can offer in-depth discussions or guides that previously didn’t fit Threads’ character limits.

Since the content is fully readable within Threads, it avoids the friction of forcing users to leave the app while still giving creators a way to drive external traffic.

Challenges and Considerations

While the feature is promising, it comes with questions:

• Will users embrace long-form posts on a platform originally built for quick updates?

• Will the algorithm prioritize these posts, or will shorter updates still dominate feeds?

• Without search indexing, how discoverable will these attachments be outside Threads?

The answers depend on adoption rates and how Meta tunes its recommendation system to surface long-form content.

Conclusion

Threads’ new 10,000-character expansion marks a turning point for the platform. What started as a micro-posting competitor to X is evolving into a hybrid space where users can share both quick updates and thoughtful, long-form insights.

For creators, the benefits are clear: free publishing tools, formatting options, and link integration all within the Threads ecosystem. While questions remain about visibility and user adoption, the update signals Meta’s ambition to position Threads as more than just a short-form app.
