About iphonesize
A size comparison for every iPhone Apple has shipped — 43 models — drawn together at true scale on one baseline.
Put up to four models in the address bar, separated by slashes, and the page draws them side by side. The URL is the whole state: what you see is what you send when you share the link, in the same order.
Every phone is drawn procedurally from its published dimensions in millimetres. Nothing here is a photograph, a render supplied by Apple, or a 3D model taken from a product page. That keeps the drawing honest about what it is: a shape built from numbers you can check.
Measurements are shown in millimetres by default and convert to inches with the switch in the header. Screen size is the exception — it stays in inches, the way Apple quotes it.
