Radius Track Corp. has introduced a free new online tool to quickly calculate radius and arc lengths at the click of a button.

“When you need an exact radius, arch length or even cord length measurement, you need accurate results. Complicated math equations are tiresome when you’re in the field and need a fast answer,” said Chuck Mears, AIA, CEO of Radius Track.

To use, simply enter any two of the following measurements: arc radius, cord height or cord length, and the tool calculates the rest. The output measurements can also be easily printed and taken to the job site.
