By now we all know that the iPhone 6 is going to be coming in two different models and now we already have these two models put out on some drawings which suggest two screen sizes and also lay out a few specific dimensions. The Japanese Apple-centric Mac Otakara publication is the source behind these schematics.
As seen through these schematics, the smaller of the two versions is going to sport a 4.7" display and will have the exact dimentions of 137 x 66 x 7 mm. If we compare this with the existing phones, then the iPhone 5s is at 123.8 x 58.6 x 7.6 mm while the 5" Nexus 5 is just 137.9 mm in height. On the other hand, the larger model is going to sport a 5.7" with dimensions of 157 x 77 x 6.7 mm and it is also taller than the Samsung Galaxy Note 3 which has the same display size. Then we move on to the two sketches which are yet to be declared as credible and they show the two models with rounder edges and a slim waistline along with single-piece volume buttons. The source from where the sketches come from has claimed that the devices sport 7.1 mm thickness and the the 3.5 mm headphone jack is located on the far left instead of the right at the bottom of the phone.
These sketches have helped to create some 3D renders which come from Martin Hajek but there is no assurance as to whether these are even somewhere closer to what the original phone looks like but still they look pretty cool and fit for an Apple device.
