About the Bluesky Character Counter
Bluesky posts cap at 300 characters — a little more room than X, less than most others. Type or paste your post to see the live count against the limit, plus how the same text fits X, Instagram, LinkedIn, Threads and more.
How to use it
- Type or paste your post into the box.
- Watch the live count against Bluesky's 300-character limit.
- Check the table for how it fits X, Threads, Mastodon and more.
- Trim until it fits everywhere you plan to post.
Why format your Bluesky text?
Bluesky's 300-character limit sits in an awkward middle: too long to reuse a tweet as-is, too short for a LinkedIn post. A live counter with the multi-network view helps you shape one message that works across the open social web and beyond.

Frequently asked questions
What is the Bluesky character limit?
A Bluesky post can be up to 300 characters, including spaces, mentions and links. This counter tracks your live length against that limit.
Is Bluesky's limit different from X?
Yes — Bluesky allows 300 characters versus X's 280, so a post that fits X will always fit Bluesky, but not always the other way around.
Can I check Mastodon and Threads too?
Yes. The table shows your length against Mastodon (500), Threads (500), X, Instagram, LinkedIn and more, so you can write once for the whole open social web.
Is it free?
Yes, free with no sign-up. And OwlKonnect natively schedules Bluesky and Mastodon posts alongside your other networks when you are ready.
