How to use the X/Twitter Thread Splitter

  1. 1Paste or type your long text.
  2. 2Keep 280 as the standard limit or enter another limit if you need one, then choose whether to add thread numbers.
  3. 3Press Split Thread, review each post, then copy posts individually or copy the whole thread.

Useful tips

  • •The splitter prefers paragraph, sentence and word boundaries instead of cutting text at an arbitrary character whenever possible.
  • •Thread numbering is included in each post's character budget, so enabling it can create an extra post for text that sits close to the limit.
  • •Review the transitions between posts before publishing so a sentence split still reads naturally in context.

Frequently asked questions

Why does the character count sometimes differ from the number of visible characters?

X/Twitter uses weighted character counting rather than simply counting JavaScript string length. The public twitter-text configuration gives many common characters a weight of one, many other characters a weight of two, treats emoji as weighted units, and counts recognised URLs using a fixed transformed length.

How are links counted?

The public twitter-text v3 configuration uses a transformed URL length of 23 characters. The splitter follows that model for common web links so a long URL does not consume its literal full length.

Does it preserve paragraphs?

When space allows, the splitter prefers paragraph breaks first, then line breaks, sentence endings and ordinary spaces. Very long unbroken text may still need to be cut at a smaller boundary to stay within the limit.

Why is 280 the default?

The public twitter-text v3 configuration sets a maximum weighted post length of 280. X can offer different posting limits in some account or product contexts, so the field remains editable.
