According to the data collection, 9% of Tweets in English hit the character limit and users find it challenging to fit a thought into a single Tweet which requires a lot of time in editing, modify and sometimes even abandoning the tweet without sending. And with double the character limit, this issue can be drastically reduced, and the number dropped to only 1% of Tweets running up against the limit according to the data collected by Twitter.
The changes will be rolling out in all languages except Japanese, Korean, and Chinese, in which space limitations have not been an issue. The average length of a tweet in Japanese is 15 characters, and only 0.4 percent of tweets hit the 140-character limit.
We’re expanding the character limit! We want it to be easier and faster for everyone to express themselves.
More characters. More expression. More of what’s happening.https://t.co/wBpYdy1K40
