I've drawn an irregular shape in illustrator and I want to know what its area is then I want to compare it between another shape

How could I calculate its area in Illustrator (CS6 or CC)?

There's unfortunately no way of getting the area in Illustrator (CS6/CC) natively that I know of.

You may have more luck with scripts.

I found one here that seems to work.

The code seems rather simple:

alert("Area & Length (inches)\nArea: " + (Math.abs(app.activeDocument.selection[0].area/5184).toFixed(3)) + "\nLength: " + (app.activeDocument.selection[0].length/72).toFixed(3));

You could also convert these measurements from inches to centimeters. The source page seems to go into some descriptions on how to customize it.

Getting area in CS-CS5

That being said you can look at it through an unsupported feature in CS5 and below (down to CS I believe) by clicking:

CTRL+ALT+SHIFT+F12

or

CMD+OPTION+SHIFT+F12

Select your path then open the object section and look at the area read-out: enter image description here

I can't tell you how to interpret that area read-out (I'd assume points) but you can use it as a point of comparison. No pun intended.

Do be careful with this feature as it is unsupported and could cause grief.

Source and alternative methods

  • Note the dev panel at F12 no longer exists past Illustrator CS5. Adobe removed the panel in CS6 and has not replaced it. It was never intended to be a feature or something users saw. – Scott Nov 14 '14 at 1:57
  • Thank you, but i'm working on cc :\ – Hassan Alkhateeb Nov 14 '14 at 7:50
  • @Scott, good to know. That was something I wasn't sure about and took for granted. I hope that my answer can still help anyone below CS6 and perhaps some of the other methods mentioned in the thread I linked to provide some sort of answer. Other than that I don't see another way of doing this. – Hanna Nov 14 '14 at 19:58
  • The panel was very helpful for this stuff and it's a shame Adobe removed it. But, like you, I'm unaware of any other method to see this data in newer versions. Hopefully someone will know. – Scott Nov 14 '14 at 20:00
  • @Scott I've updated my answer. The script seems to work in CC as well. Not entirely sure on the accuracy as my math skills aren't too hot, but it seems to do the job. – Hanna Nov 14 '14 at 20:10

If Johannes method fails to work for you, Telegraphics have a free Patharea filter which may do the trick: http://www.telegraphics.com.au/sw/product/patharea

  • thank you, the plug-in extension is >dmg and the plug-ins in the folder of illustrator files are .aip so, how to deal with ? – Hassan Alkhateeb Nov 14 '14 at 8:01
  • I'm guessing you're using a Mac. The dmg contains the aip that you're after – KJP Nov 14 '14 at 8:22

Bryan Buchanan made a script available on github to compute the area of a shape in Illustrator in squared cm or squared inches. I used it on Adobe Illustrator CC 2020.

In order to use the script you have to:

  1. Download the file as .jsx (right click on "raw" and then "save as" somewhere on you computer).
  2. Select in Illustrator the shape(s) you want to measure with the black arrow
  3. Go to File/Scripts/Other scripts... (or shortcut Ctrl+F12)
  4. Select the .jsx file in the folder pannel

The shape(s) area will be displayed in a pop-up window.

If you want the script to appear directly in the File/Script menu, you have to place the ".jsx" file in the subfolder Scripts in Presets. The exact path to that folder depends on you operating system, Illustrator version and language, but should look like this on Windows:

C:\Program Files\Adobe\Adobe Illustrator 20xx\Presets\en_GB\Scripts
