Im still working on some other issues inbumpedninto. I noticed when a selection consists of multiple compoundpathitems, it would return the shape count as 1. Currently working on that. I believe the calculations are now fixed. As far as I can do that. I've noticed that still sometimes it returns a none round number even when the length and with are round numbers.. the pixel area is now as close as I can get it
Cool, thanks for updating this and helping out! I appreciate all the work you've done. Will you update the code when you iron out those bumps you were talking about?
Of course I will
For some reasons, it got negative area for some paths, so for multiple paths it substracted them. not added. Fixed with adding math.abs:
var totalArea = totalArea + Math.abs(objects[i].area);
But unfortunately, now compound shape calculation doesn't work correctly ¯_(ツ)_/¯
Love this! I think it would fit into a project I'm working on.
Does anyone think it would be possible to give the total area of every spot colour in a document? I am limited by having to select the shapes.
now compound shape
Yeah, this original version is great but is minimal. You can also have a look at my altered version. There is still a minor issue now, it has some issues sometimes with a combination of pathItems and compoundPathItems mixed together.

Im not sure adding this to the script will help. Its kinda of a specific workflow
Have a look at my version. It has been updated with more functionality
https://github.com/schroef/Illustrator-Scripts/blob/master/GetShapeArea-dialog.jsx
You can easily use magic wand to iterate over colors and than run the script each time
Yeah, there seems to be a narrow margin of error that gets exponentially more noticeable. Glad to help where I can!
