How it works

Choose a shape and the relevant inputs appear. Everything is computed with standard plane-geometry formulas.

Frequently asked questions

Can I use it for square footage?

Yes. Enter your measurements in feet and the area comes out in square feet.

Does it mix units?

No. Use the same unit for every input and the result uses that unit squared.
