Did some calculations and found something kind of interesting. The current iPhone 5/5S screen size is noted as 4 inches...more precise measurements are 100mm for 5/5S, the 6 is 120mm, and the 6 Plus is 140mm. When you actually convert it to inches you get this:
25.4mm = 1 inch
iPhone 5/5S: 100mm/25.4mm = 3.937 inches
iPhone 6: 120mm/25.4mm = 4.724 inches
iPhone 6 Plus: 140mm/25.4mm = 5.511 inches
Looking at these numbers, the difference between a 5/5S and 6 is closer to 0.8 inches than 0.7. (4.724 - 3.937 = 0.787 inches) and then the difference between a 6 and 6 Plus is (5.511 - 4.724 = 0.787 inches). Yea this all seems insignificant, etc, etc. But it is interesting to note that the 5/5S was still barely shy of 4 inches where as the 6 and 6 Plus are a solid 4.7 and 5.5. Cue the "who cares" comments....just thought some people might find this interesting.
EDIT**
iPhone 5/5S: 326ppi with 1136x640 resolution with that we get the following:
P. Theorem a^2 + b^2 = c^2
((1136/326)^2) + ((640/326)^2) = 15.996
sqrt(15.996) = 3.9994 inches
iPhone 6: 326ppi with 1334x750 resolution:
((1334/326)**2) + ((750/326)**2) = 22.037
sqrt(22.037) = 4.694 inches
iPhone 6 Plus: 401ppi with 1920x1080 res.:
((1920/401)**2) + ((1080/401)**2) = 30.178
sqrt(30.178) = 5.493 inches
These are your actual display sizes.
