After an initial surge of tweets hitting the new total, the novelty of the 280 character limit soon wore off.
"We believe people spent less time editing their Tweets in the composer", said Rozen. It also saw people with the longer character limits have more likes, retweets and mentions, get more followers and spend more time on the platform.
The announcement comes just a few months after Twitter started testing a 280-character limit for a set number of users around the globe, courting concern from users who were anxious that banishing brevity would clog up their timelines.
Increasing the character limit should not affect people's experience on the site, she added.
Twitter claims that among the trial users "5% of Tweets sent were longer than 140 characters and only 2% were over 190 characters".
Twitter is now officially making 280-character tweets available to everyone after testing longer tweets with a subset of its users for the past two months. In a company blog post, Twitter Product Manager Aliza Rosen explained the new character limit would apply to all languages except for Japanese, Chinese and Korean, because those languages already allow their native speakers to convey roughly twice the amount of information in one character compared with many other languages, including English, Spanish and Portuguese.
Twitter previously prided itself on its limit, which forced people to edit their views and opinions and think hard about getting it all in. "People did silly (creative!) things like writing just a few characters per line to make their Tweets extra large".
Twitter's character limit was created so that tweets could fit into a single text message, back when many people were using texts to receive tweets.
'It was a temporary effect and didn't last long. For reference, in the timeline, Tweets with an image or poll usually take up more space than a 190 character Tweet.
Numerous concerns about 280 characters from Twitter users revolved around bloated timelines and a decline in the UX.
The company says: "Our goal was to make this possible while ensuring we keep the speed and brevity that makes Twitter, Twitter".
