Split long text into a numbered thread of tweets, each under the 280-character limit.
This tool splits a long piece of text into a properly numbered thread of tweets, each kept under the 280-character limit (with room reserved for the "1/n" numbering itself), breaking only at word boundaries so no word is cut mid-way.
Paste your full text. The numbered thread appears instantly, ready to copy tweet by tweet.
The tool first breaks your text into words wherever there is any whitespace, then builds tweets by adding words one at a time. It reserves 8 characters from the 280 limit for the numbering suffix, so each tweet body is kept to 272 characters or fewer. When the next word would push the current tweet over that budget, the tweet is closed and the word starts the next one. After chunking, each tweet gets a suffix such as 1/4 appended after a space, where the second number is the total count. Each tweet in the output also shows its own character count so you can confirm it fits.
Imagine a 900-character essay. With a 272-character body budget, it would be split into four tweets, because three tweets could hold at most about 816 characters and the text is longer than that. The output would end each tweet with 1/4, 2/4, 3/4 and 4/4. The last tweet is usually shorter, since it holds whatever is left over. Copy each one in order and post it as a reply to the previous one.
Write the whole piece first, run it through the splitter, then edit the output. Start the first tweet with the point most likely to make people read on, since it is the only one shown in most feeds. If your edits add characters, watch the character counter shown beside each tweet. If a tweet grows past 280 after your edits, move the last words to the next tweet by hand. Removing filler words before splitting can also reduce the number of tweets, which readers tend to appreciate.
The 280-character figure is the standard limit; accounts with longer-post features can post more, and X counts links and some characters by its own rules, so a tweet close to the limit might count differently on the platform. Emoji may also count as more than one character. The reserved 8 characters are a safety margin, meaning tweets are sometimes a little shorter than strictly necessary. Nothing is posted or stored by the tool; it works entirely in your browser.
No -- this is a text-splitting tool only, entirely client-side. You copy and post each tweet yourself.
The tool reserves 8 characters for the numbering suffix, so each tweet body is capped at 272 before the suffix is added.
Not automatically. The tool joins words with single spaces, so re-add the breaks manually after copying each tweet.
A word longer than the budget is cut into pieces so no tweet exceeds the limit, but a cut link is not clickable. Shorten the link first.
It helps readers follow the order, and the tool does it for you. You can delete the suffixes if you prefer an unnumbered style.
