Need to find the area of a selected object in Illustrator? Illustrator can’t do it on its own, but you’re in luck — there’s a free filter for Illustrator that will.
Go to the Telegraphics website and download the free Path Area filter. Yes, free.
It’s intended for CS2, but I found that it will also work in CS3 and CS4, although it appears under a different menu in CS4.
Download and unStuff or UnZIP the archive (it’s available for Windows and Mac; I confess that I haven’t tried it on Windows), then copy the “patharea_cs2.aip” file into the Adobe Illustrator/Plug-ins/Illustrator Filters folder.
To use in CS2 or CS3, select an object, and choose Filter > Telegraphics > Path Area.
In CS4, select an object and choose Object > Filters > Telegraphics > Path Area.
A dialog appears, displaying the linear length of the path, plus the area in millimeters squared and square inches. It’s a one-trick pony, but it’s very good at the trick.
