Twitter is set to increase the number of characters allowed in a single tweet to 10,000 from the current limit of 140.
Chief executive Jack Dorsey posted a message saying the company will not be ‘shy’ about giving its users more power, noting that many find ways to circumvent the current character limit anyway by attaching images packed with text.
Dorsey posted used a picture containing 1,325 characters to tell followers of the service what may be in store.
He said the current limit ‘inspires creativity and brevity’ and that the majority of tweets ‘will always be short and sweet and conversational’, but added they are keen to work to ‘strengthen’ the site's purpose.
He wrote: "We're not going to be shy about building more utility and power into Twitter for people. As long as it's consistent with what people want to do, we're going to explore it."
In recent times the social networking site has recently been struggling with low share prices and competition with Facebook, which has more than 1.4 billion active users compared with Twitter's 300 million.
While Facebook does not restrict the number of characters that users can post in messages on the site, a number of Twitter 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.
Some users took to Twitter to express their opposition to the possible longer tweet with the hashtag #beyond140.
Twitter is reportedly considering launching the service toward the end of the first quarter, but has not set an official date so far.
