What is the character limit per tweet?

280 characters for free Twitter / X accounts. The tool splits at 280 by default. If you have X Premium and want longer tweets, you can paste each tweet manually — the tool does not currently support custom limits.

Why is my tweet slightly shorter than 280?

Because the splitter reserves space for the optional number label (e.g. “7/12 ”), the 🧵 emoji, and any first-tweet prefix you set. The body is truncated with an ellipsis if it would otherwise overflow.

How does the splitter handle paragraphs?

Blank lines (paragraph breaks) act as hard splits — the current tweet ends and a new one starts. Single line breaks inside a paragraph are normalised to spaces.

Can I copy individual tweets?

Yes. Each tweet card has a Copy tweet button. The Copy all button copies the whole thread separated by lines of dashes so you can paste it into a notes app or scheduler.

Social Media Tools

Twitter Thread Formatter

Turn a long piece of text into a numbered Twitter / X thread. The splitter breaks your draft into tweets of at most 280 characters on word boundaries, numbers each one (1/N), and optionally adds the 🧵 thread emoji to the first tweet. Copy the whole thread or grab individual tweets one at a time.

How to use

1
Paste your long text
Drop in a blog draft, article, or any block of writing. Paragraph breaks (blank lines) become natural split points.
2
Pick your options
Toggle tweet numbering (1/N), the 🧵 thread emoji, character counts, and an optional first-tweet prefix like “🧵 A thread:”.
3
Review each tweet
Each tweet is shown on its own card with a live character count. The counter turns amber near the limit and red if something overflows.
4
Copy the thread
Use Copy all to grab the whole thread as plain text separated by lines of dashes, or copy individual tweets one at a time.

Common use cases

Turn a 1,000-word blog post into a 10-tweet thread for X.
Split a long LinkedIn post for cross-posting to X.
Prepare a launch announcement as a numbered thread.
Share meeting notes or a conference recap as a sequential thread.

Limitations

The 280-character limit reflects free Twitter / X accounts. X Premium subscribers can post longer tweets — this tool always splits at 280.
The splitter does not detect URLs specially. URLs count toward the 280-character limit just like any other text. (Twitter shortens URLs to 23 characters on publish, but this tool cannot know which URLs will be shortened.)
Images, videos, polls and quote tweets are not handled — the tool outputs plain text only.
The 🧵 emoji is treated as two characters (it is rendered as a single grapheme but counts as 2 in JavaScript string length). The splitter accounts for this.
