The micro blogging site are currently trialling a new feature for when the new 280 character limit still isn't enough.
Some users already have this feature, which activates when you press "Tweet all".
It comes after Twitter extended its character limit to 140 to 280 characters per message.
Aliza Rosen, Twitter's Product Manager, wrote at the time: "In September, we launched a test that expanded the 140 character limit so every person around the world could express themselves easily in a Tweet. Our goal was to make this possible while ensuring we keep the speed and brevity that makes Twitter, Twitter. Looking at all the data, we're excited to share we've achieved this goal and are rolling the change out to all languages where cramming was an issue.
"During the first few days of the test many people Tweeted the full 280 limit because it was new and novel, but soon after behavior normalized (more on this below). We saw when people needed to use more than 140 characters, they Tweeted more easily and more often. But importantly, people Tweeted below 140 most of the time and the brevity of Twitter remained."
And the team have insisted the new longer tweets won't affect people's timelines.
They added: "We - and many of you - were concerned that timelines may fill up with 280 character Tweets, and people with the new limit would always use up the whole space. But that didn't happen. Only 5% of Tweets sent were longer than 140 characters and only 2% were over 190 characters. As a result, your timeline reading experience should not substantially change, you'll still see about the same amount of Tweets in your timeline."
