Following reports that Apple is working on a bigger iPhone that could sport a display between 4.8in and 6in diagonally, analysts have chimed in with their predictions of a bigger iPhone.

On Friday, we reported that the Wall Street Journal has claimed to have spoken to sources who say Apple has been testing iPhones with screens ranging from 4.8in to 6in, which would make the device significantly bigger than the iPhone 5, which has a 4in screen.

Now, KGI analyst Ming-Chi Kuo and Cantor Fitzgerald analyst Brian White have both shared their predictions of a bigger iPhone.

Apple Insider reports that Kuo has said in a research note that Apple is likely to launch an iPhone with a bigger screen next year, but that the company will opt for 4.5in or 5in rather than the larger, 6in screen that WSJ's report suggested.

Kuo explains that Apple is unlikely to launch an iPhone with a screen bigger than 5in because of its "unwavering principle of one hand use." Apple explicitly put the reason for the 4in display on the iPhone 5 down to the ability to operate a screen that size using just one hand.

Meanwhile, White has said that, although we shouldn't expect to see a bigger iPhone at Apple's 10 September event, it's highly likely that a bigger iPhone will be launched in 2014.

White calls the bigger iPhone "Mega iPhone," and says that such device could help Apple expand its reach in China and the rest of Asia.

"At the end of last year, our research in Asia uncovered early stage work on iPhones with a larger screen size," White wrote in a research note shared by Venture Beat. "A lower price point for the iPhone 5C should help Apple in China; however, we believe a mega-sized smartphone, or "iPhad" device, has the potential to provide a further boost to sales."

Apple's 10 September iPhone event is set to kick off at 6pm BST, and could see the unveiling of iPhone 5S, iPhone 5C and the roll out of iOS 7, as well as some Mac updates and the launch of OS X Mavericks.
