According to the Wall Street Journal, sources claim that Apple is working on phones with screens ranging from 4.8-inches up to six-inches.
Apple has previously refused to comment on speculation that it may be working on iPhones with larger screens.
The company has only ever increased the size of its screen once in the history of its iPhone range, between the iPhone 4S and the iPhone 5.

Its upcoming smartphones, the iPhone 5S and iPhone 5C are expected to come with the same four-inch screen found on the iPhone 5.
Apple has previously been rumoured to be working on larger screen phones.
Back in the middle of summer, a number of reports emerged suggesting that the company was investigating the alternative screen sizes. At the time, it was put down to pressure to respond to the growth of Android.
The WSJ report also reiterates previous rumours suggesting that the iPhone 5S will come with a fingerprint scanner. Apple is holding an event on Tuesday where it is widely expected to officially unveil its next generation of iPhones.
