Question by Professor Know It All: Why is it that when I use Twitter from a web browser I only have 140 characters but from mobile apps I get 160?
all the apps on my iphone (Twitteriffic, Vlingo etc) allow me 160. I though twitter WAS 160. Then I actually posted from my home computer, (kind of defeats the purpose, I know) but everywhere I look on wikipedia etc, it seems that Twitter is famous for its 140 characters, not 160. But I can post at a length of 160 from my phone. hmmm…

Best answer:

Applications for mobiles tend to conform to the SMS limit, which is indeed 160.

People have managed to post tweets of 250 characters, though this seems to eat two API calls instead of one.
