Many rumors have been surfacing in the smartphone industry about a larger 4.8-inch iPhone, a.k.a iPhone Math. However, Apple's CEO, Tim Cook has squashed all speculations and hinted that a bigger iPhone is not on the cards for the company.

Apple launched the iPhone 5 in September last year, which sported a 4-inch display, bigger than any of its previous iterations. Just after the launch of the iPhone 5, rumors regarding a next-generation iPhone sporting even a bigger display have started trickling in.

"The iPhone 5 screen offers a new four-inch retina display. It also provides a larger screen without sacrificing one-handed use. We put a lot of thought into screen sizes and we think we picked the right one," said Cook.

It is interesting that Cook's comments do not directly dismiss the plans of a bigger iPhone. The smartphone space is getting flooded with bigger size smartphones and the 4-inch iPhone looks puny in front of Galaxy Note 2, Droid DNA, et al.

Furthermore, most of the upcoming smartphones are rumored to be more that 4.7 inches. Apple slightly increased the size of the iPhone in the iPhone 5, but the current trend and demand for bigger smartphones may prompt Apple to launch a bigger iPhone soon.

At the launch of the iPad, Steve Jobs indicated that a smaller iPad is not something the company will offer. However, the company did release the 7.9-inch iPad mini in October last year.

Many concept videos and images of a larger iPhone have been circulating recently, which show what a bigger iPhone may look like. Till Apple does not announce a larger iPhone, we will have to contend with concepts of a larger iPhone instead.
