Form factor vs price point

A few years ago I noticed people started saying “form factor” when they talked about the design of electronic devices. I found it annoyingly jargony and uneconomical, kind of like “price point”, which means price. Yesterday my friend Ryan used the term in reference to the shiny iPhone he was about to buy. On reflection I guess it’s not quite as bad as “price point.” “Form factor” refers to both the size and the shape of an object (and it appears to be used in a semi-technical way in electronic engineering), and I can’t seem to think of a single term that refers to both size and shape. Any ideas?
