On Sept. 27 the company’s official account tweeted that it will experiment with increasing the character limit to a tweet from 140 to 280 characters. "Although we feel confident about our data and the positive impact this change will have, we want to try it out with a small group of people before we make a decision to launch to everyone," the blog post said. Currently, 140 characters limit tweets can be made by users, however, with this new feature, users can double the amount of characters to tweet, so now it is possible to tweet 280 characters tweets. — Biz Stone (@biz) September 26, 2017

Twitter today announced that it is going to "try out" a longer character limit, doubling the current 140-character limit to 280 characters.The 280 character limit is going to be available in languages that are "impacted by cramming," aka all languages aside from Japanese, Chinese, and Korean.According to Twitter, most tweets in English have 34 characters while most tweets in Japanese have 15 characters, and Twitter users tweeting in English hit the 140-character limit more often, which can be a "major cause of frustration. The test is sure to provoke a strong reaction among Twitter’s hardcore users, who have a long history of reacting strongly to changes in the service’s fundamentals, such as Twitter’s decision to transform the timeline from reverse chronological order to one that’s algorithmically sorted.
