Threads Character Limit Tips

Posts are capped at 500 characters

Threads posts have a 500-character limit, making it closer to the original Twitter experience than most other platforms. Every word needs to earn its place. Write, then edit down ruthlessly.

Bio mirrors Instagram at 150 characters

Your Threads bio allows 150 characters and is separate from your Instagram bio. You can customize it differently to address the Threads audience specifically.

No hashtag system changes the strategy

Threads supports topic tags but not traditional hashtags. You can add one topic tag per post, which does not count against your 500-character limit. Choose the single most relevant topic.

Replies share the same 500-character limit

Replies on Threads also have a 500-character limit. Use reply chains to continue a thought across multiple posts if you need more space for complex topics.

Links count toward the character limit

Unlike X (Twitter), URLs on Threads count at their full length toward the 500-character limit. Use a link shortener or place links strategically to preserve space for your message.
