Bluesky Thread Maker
Auto-splits long text into 300-char posts. Sentence-aware.
How Bluesky threads actually work
Each post on Bluesky caps at 300 characters, and the count runs on graphemes rather than raw bytes, so emoji and accented letters cost one slot each instead of several. A thread is just a chain of replies you stack under your own first post. The detail most people miss: links, @-mentions and #hashtags are all measured by their full visible text, so a long URL eats into your 300 fast. Splitting your idea at natural sentence breaks keeps every post readable on its own and stops the app from cutting a thought mid-line.
Bluesky thread tips
- Front-load the first post; it is the only one that appears in feeds, so make it stand alone.
- Each post allows 300 characters counted as graphemes, so plan splits at sentence ends, not mid-word.
- Long URLs count toward the 300 limit and are not shortened, so keep one link per post where possible.
- Add alt text to any images; Bluesky supports it and screen-reader users rely on it to follow your thread.

Bluesky Thread Maker — common questions
Latest questions readers ask us about this topic.
What's the character limit for a Bluesky post?
Each Bluesky post allows up to 300 characters, counted by graphemes. That means an emoji or accented character takes a single slot, not several bytes, but mentions, hashtags and full URLs all count toward the same 300.
How do you make a thread on Bluesky?
Post your first message, then tap the reply icon on your own post and keep replying to build the chain. Drafting each segment under 300 characters first, then posting in order, avoids awkward mid-sentence breaks.
Do links and hashtags count toward the Bluesky limit?
Yes. Bluesky counts the full visible text of every link, @-mention and #hashtag against your 300 characters, and URLs are not auto-shortened, so a long address can quietly consume a large share of one post.
