💡 Frequently Asked Questions
Q: What is the text character limit on Bluesky?
Bluesky enforces a strict maximum of 300 characters per single update or thread post.
Q: How should I split a 2,000-character Bluesky essay without breaking the argument?
Paste the full text into the splitter, select sentence-aware parsing, and target 240–280 characters per post. Review every break manually so each post has a complete thought, then add numbering and confirm every final post stays at or below 300 characters.
Q: Why does my Bluesky thread splitter count emojis and links differently from my word processor?
Bluesky limits posts by characters, while some editors count words, code points, or visible symbols differently; compound emojis can therefore produce unexpected totals. Use the tool’s final Bluesky-style count, keep a 20–40-character safety margin, and recheck after inserting URLs or mentions.
