Rosen said expanding the character limit from 140 characters to 280 will give users more space to fit in their thoughts.
Historically, she said, nine percent of tweets typed in English hit the character limit, which results in a lot of time spent editing a single tweet or eventually abandoning tweets before sharing them.
In September, Twitter launched a test for select users to have access to the expanded 280-character limit. As a result of the experiment, researchers found only one percent of tweets in English hit the character limit.
“People in the experiment told us that a higher character limit made them feel more satisfied with how they expressed themselves on Twitter, their ability to find good content, and Twitter overall,” Rosen wrote.
However, tweets in Japanese, Korean and Chinese will continue to have the 140-character limit, because cramming characters is not an issue for the languages due to the density of their writing systems, she said.
