Threads Updates: How Does The Recent Feature For Longer Posts Work?

Meta's Threads platform has just rolled out one of its most significant updates since launch: a feature that substantially changes how users can share content on the platform. If you've been frustrated by the 500-character limit or tired of creating lengthy thread chains to express complex ideas, this new text attachment feature is about to transform your Threads experience.

What's New: Text Attachments on Threads

In September 2025, Threads officially launched a feature that allows users to attach up to 10,000 characters of text to a single post. This represents a massive leap from the standard 500-character limit that users have been working with since the platform's inception.

The feature was first spotted during testing in late August 2025 by app researcher Radu Oncescu, and Meta quickly confirmed its rollout to TechCrunch. What started as a limited test has now become available to users, addressing a common pain point that had many resorting to creative workarounds.

Why Threads Needed This Feature

Before this update, users faced a familiar dilemma: how do you share insightful thoughts, lengthy excerpts, or detailed analysis when you're limited to 500 characters? The answer wasn't grand

Many Threads users developed workarounds that felt clunky and unprofessional:

• Screenshot sharing: Taking screenshots of text from Notes apps, articles, or other documents and posting them as images

• Thread chains: Breaking content into multiple connected posts, which often disrupts the flow of ideas

• External linking: Directing audiences away from Threads entirely to read content elsewhere

Meta noticed these patterns and recognized that users were clearly hungry for more space to express themselves. The platform observed people regularly sharing screenshots of content from books, articles, newsletters, and podcast transcripts: all signals that the character limit was becoming a creative constraint rather than a helpful boundary.

How the Text Attachment Feature Works

The new feature is remarkably straightforward, designed to integrate naturally into the existing Threads posting experience.

Creating a Post with Text Attachment

When you create a post on Threads, you now have the option to attach a text block of up to 10,000 characters. This attached text appears differently from your main post:

1. Main post area: You still have your standard 500-character post where you can write an introduction, summary, or hook

2. Text attachment: The longer content appears in a gray box within your post

3. Preview snippet: Viewers see a preview of the attached text directly in their feed

4. Expandable content: Users can click or tap to read and scroll through the full content without leaving Threads

Styling and Formatting Options

According to the feature's description, users can “get creative with styling tools” when formatting their text attachments. This allows for better organization and readability of longer content, making it easier to share:

• Deeper thoughts and analysis

• News snippets and commentary

• Book excerpts and literary content

• Article previews or full pieces

• Detailed tutorials or guides

Linking to External Content

One particularly useful aspect of this feature is the ability to include links in your main post that direct readers to the full version of your content on other platforms. This makes text attachments perfect for:

• Authors teasing portions of forthcoming novels

• Journalists promoting their latest articles or think pieces

• Newsletter writers sharing previews from Reddit or similar platforms

• Content creators driving traffic to their blogs, websites, or other platforms

How Threads Compares to X (Twitter)

The timing of this feature is notable, especially when considering the competitive layout. X (formerly Twitter) already offers long-form content through its Articles feature, but there are key differences:

Threads Advantages:

• Free for all users: Unlike X's Articles feature, which is limited to Premium subscribers, Threads' text attachments are available to everyone

• Simpler format: The text attachment approach feels more inherent to the feed experience

X Advantages:

• Multimedia support: X's Articles allow users to incorporate images and videos alongside text

• More established: The feature has been available longer and may have more polish

However, since Threads' feature is still relatively new, Meta may add multimedia support and additional formatting options in future updates.

Who Benefits Most from This Feature?

The text attachment feature opens up new possibilities for various types of content creators and users:

Writers and Authors

Authors can share compelling excerpts from their work, building anticipation for upcoming releases or driving readers to published pieces. The 10,000-character limit provides enough space for a meaningful sample that can hook readers.

Journalists and Thought Leaders

Professional writers can promote their articles and thought pieces while providing enough context to engage their audience. Instead of simply sharing a link with a brief description, they can offer substantial previews that demonstrate the value of the full piece.

Educators and Experts

Subject-matter experts can share detailed explanations, tutorials, or educational content without fragmenting their message across multiple posts. This makes Threads a more viable platform for in-depth knowledge sharing.

Business Professionals

Professionals can share comprehensive insights, case studies, or analyses that would have previously required external platforms or awkward workarounds.

The Broader Impact on Threads' Ecosystem

This feature represents more than just a quality-of-life improvement. It's a strategic move that could reshape how people use Threads.

Retaining Creators

By offering long-form capabilities, Threads becomes more competitive in retaining creators and writers who might otherwise exclusively use platforms like Substack, Medium, or their own blogs. Creators can now use Threads as both a promotional tool and a content platform itself.

Improving User Experience

The elimination of screenshot workarounds creates a cleaner, more professional feed. Native text attachments are searchable, copyable, and more accessible than image-based text, improving the overall user experience.

Growing the Platform

With over 400 million monthly active users as of late 2025, Threads is experiencing rapid growth. Features like text attachments help differentiate the platform and give users compelling reasons to choose Threads over competitors like X, which has north of 600 million monthly active users.

The Challenge of Organization: Finding Your Saved Content

As Threads introduces features that encourage more substantial content sharing, a new challenge emerges: how do you keep track of all the valuable posts you save?

With richer, longer content now appearing in your feed, you're likely to save more posts than ever: articles, insights, resources, and ideas you want to revisit. But as anyone who regularly saves content knows, the real challenge isn't saving, it's finding what you saved later.

This is where content organization becomes critical. Threads' default saved posts feature allows you to bookmark content, but searching through hundreds or thousands of saved items can feel like navigating a maze. Without proper tagging, categorization, or search functionality, those brilliant insights you saved might as well not exist.
