Trace Width Calculator

Ensure accuracy and consistency with a PCB trace width calculator

Overview

Calculating Your Estimate

One of the most important features of any PCB project is trace width, which refers to the measurement of the electrical conductors. The right trace width means you will not only have the correct amount of current, but your printed circuit board will not overheat. A trace width calculator can help you make those estimations. Also, keep in mind that a higher current means a thicker trace, and thicker copper can allow for a thinner trace. Disclaimer: It’s also important to remember that these calculators are just estimates, and they may not be appropriate for every project.
