What if an iPhone Plus used Retina iPad screens with iPhone 5 resolution, keeping the rest of the design sized like an iPhone 5? Its 640 × 1136, 264 DPI screen would measure 4.94” diagonally, and it would look roughly like this next to an iPhone 5.
Arment notes that keeping the pixel dimensions the same as the iPhone 5 means that no app changes would be necessary and two-handed use would be easier because the touch targets would be larger.
One reason why Apple could consider a larger phone is the significant demand for larger devices.

Take a look at the images below for a better sense of what the larger device might look like.
