Introducing Math Tools

By Anthony Dito

BrushCue's new math tools cover geometry, arithmetic, and trigonometry — and the same computations are available in BrushCue Script for building image editing pipelines.

Frequently asked questions

What is the formula for the area of a square?
Area = side², or side × side. Just square the length of one side.
How is a square's area different from its perimeter?
Area measures the enclosed surface (side²); perimeter is the total distance around all four sides (4 × side).
How do I find the side length from a known area?
Take the square root of the area — if area = 16, the side length is 4.
Is this tool free to use?
Yes — completely free, no account needed. Everything is calculated entirely in your browser and never uploaded to a server.

For developers

Use Square Area from Python

Open the Jupyter notebook example to see how to run this tool from the BrushCue Python API, inspect the processing steps, and adapt the workflow for scripts or batch image jobs.
