iOS Devices By Shape
This reference graphic shows every profile used across iOS devices—the silhouette of the bottom side. The renderings are not to scale—iPhones range in size from 3.5″ to 6.5″ displays, iPads from 7.9″ to 12.9″ displays. This illustrates the usage of different corner stylings over the years. Minor changes are grouped together such as the protruding glass on the iPhones 4 and 4s, the ‘diamond-cut chamfered edge’ that is cut into the iPhones 5, 5s and SE and the slight corner radius on the iPhone 5c.
Going in, I had no idea the chamfered-edge-rounded design would be the longest list. I’ve never owned any of those devices.
If you are attentive you will have noticed some series of devices have version numbers in parenthesis and some do not. iPhones all have their version numbers as part of their name—they are marketed as iPhone 4, 5, 6, etc. iPads are on-and-off: their marketing names start from iPad, iPad 2, the new iPad, iPad with Retina display, and from there they diverge into iPad Air and iPad (again). If the series begins with a version-named product I list them without parenthesis.
