Threads Character Limit: How Many Characters Can You Post? (2026)

The Threads character limit for a single post is 500 characters. That’s the maximum number of characters you can type in the main post box when creating a Threads post. How many characters you can post on Threads is shown in the app with a live counter as you type. Threads (Meta’s text-focused app) uses this limit so posts stay concise and readable in the feed. In some regions Threads also supports text attachments—separate long-form text up to 10,000 characters attached to a post—but the main post itself remains 500 characters. For 2026, the core Threads post character limit is 500. Compare with Twitter character limit (280) and LinkedIn post character limit.

Everything you type in the main post counts toward the 500-character Threads limit: letters, numbers, spaces, punctuation, links, hashtags, and @mentions. There is no special shortening for URLs—each character in a link counts. So if you want to leave room for a link or hashtags, keep the body of your post shorter. The in-app Threads character count updates as you type so you can stay under 500. Line breaks also count as one character each. For more room, use a text attachment (where available) for long content and keep the main post under 500 characters.

Threads has introduced text attachments that let you attach up to 10,000 characters to a post in supported regions. The main post still has a 500-character limit; the attachment is separate and appears as an expandable block below the post. So you can write a short 500-character caption and attach a long article or thread-style text. Availability may vary by region and app version; check your Threads app for the text attachment option (often a rounded rectangle or document icon in the composer). This is useful for optimizing your posts when you have a lot to say: hook in the main post, detail in the attachment.

To get the most from the Threads character limit in 2026:

• Lead with the hook — Put the main point or question in the first line so it shows in the feed.
• Use line breaks — Short paragraphs and line breaks improve readability within the 500 characters.
• Reserve space for links or hashtags — If you add a link or hashtags, they count; leave room so you don’t have to cut the message.
• Use text attachments for long content — When available, put the short version in the main post and the long version in a text attachment.
• Check the counter — The app shows how many characters you have left; stay at or under 500 for the main post.
