A powerful ExtendScript for Adobe illustrator to find Center of Mass (Centroid)
Centroid Finder for Adobe Illustrator is a precision tool built for designers who want to achieve true visual balance not approximations or endless eyeballing.
While Adobe Illustrator provides geometric centers, it has no native way to calculate the true center of mass — a critical requirement for balanced logos, complex compositions, perfectly weighted icons, packaging layouts, and any design where visual balance must be precise.
This script bridges that gap with a simple, intuitive workflow. Select your object(s), run the centroid-collect.jsx script, and we calculate the precise
centroid using an advanced mathematical algorithm. Then, with a single click, the centroid-create.jsx script places that exact centroid
point into your document.
For designers who need mathematically accurate centroids for logos, icons, and complex vector forms. This is the tool you’ll wonder how you lived without.

The center of mass is created
Note: The first time you use centroid-collect.jsx, macOS may warn: compute cannot be opended. You need to Open System Settings → Privacy & Security. Scroll until you see a message about compute. Click Allow Anyway.
