Longer tweets right around the corner? How Twitter could stretch its 140-character limit5
The change would be all about how Twitter deals with links and images. Right now the service already attempts to mitigate their impact on tweet length by automatically shortening links, but the inclusion of either links or images still takes away some of those 140 characters you start out with; as a result, tweets containing either are forced to be slightly shorter.
For even a simple link, that means freeing up an additional 23 characters – and in Twitter's tight space constraints, those 23 extra characters can go a long way towards making tweets more readable or even more entertaining.
Twitter CEO Jack Dorsey recently stated that the company wouldn't be doing away with its famous 140-character limit. By changing how those characters are counted, as this rumor suggests Twitter's about to do, the service may have found a sly way to stay true to its word while effectively raising that limit for many tweets.
