Rumors of a purported 5-inch iPhone being in the works at Apple have taken the tech world by surprise, but many have been wondering if such a device might actually make sense. The Instapaper developer Marco Arment seems to believe that the so called 5-inch “iPhone Math” could become reality by creating some mock-up versions of the device. However, he prefers to call the device iPhone Plus.
Arment noted that the Retina Display iPhone offers a resolution of 326 pixels/inch, while the Retina Display iPad features a more limited 264 pixels/inch display. Following this train of thought, the developers managed to calculate that if Apple were to release an iPhone with a 4.94 inch screen the device will sport 264 pixels. However, the screen could match the iPhone’s 5 1136 x 640 resolution.
“The theory is easy to understand: perform John Gruber’s Mini-predicting math backwards. The iPad Mini uses iPhone 3GS-density screens at iPad resolution. What if an iPhone Plus used Retina iPad screens with iPhone 5 resolution, keeping the rest of the design sized like an iPhone 5?”
In order to make everything more intuitive, Arment placed the mockup device he created between the Samsung Galaxy S 3 and the Samsung Galaxy Note 2, adding the iPhone 5 too, so people might get an idea how of what Apple might intend to do in the Math/Plus concept, design wise. Arment also inserts his mockups in an Apple product assembly line, so users might get an idea how big the device could be.
