Twitter is reportedly working on a new product that will allow users to write tweets longer than the current 140-character limit.
The company's executives are also discussing changes to how the character limit is measured. They are considering excluding elements such as links and user handles from the character count to allow for longer posts.
The new product, first reported on technology website Re/code, follows a recent deceleration in user growth for the site. Twitter reported that its second-quarter monthly average users grew at the slowest pace since the company went public in 2013.
In June, the chief executive of the social network Dick Costolo stepped down after the firm failed to deliver on the expectations of investors.
He was replaced with co-founder Jack Dorsey who is currently leading the company as interim CEO and is trying to rekindle growth in its user base.
The proposals to abandon the current character limit could be designed to offer greater competition against Facebook, where there is no limit on the length of the posts.
Earlier this year, Twitter sent some of its high profile users a message suggesting that they use its in-house photo service instead of the popular, Facebook-owned, Instagram service.
Several users and designers have expressed concerns about the changes to the character limit as the brevity of posts on the site is considered to be one of its defining features.
A Twitter spokesperson declined to comment on the proposals.
The company has already been working on ways to make its service easier to use and entice people to spend more time with it.
Twitter removed the 140-character limit from its direct messages in August and announced plans to let users buy goods and make political donations through tweets.
Twitter shares were up 1.1 per cent at $25.53 (£16.79) in afternoon trading on the New York Stock Exchange. Up to Monday's close, the stock had fallen nearly 30 per cent this year.
