Welcome to the PCB Trace Width Calculator! This tool helps you determine the optimal width of a copper trace for your PCB design, ensuring it can safely carry a specified current without exceeding a desired temperature rise. By inputting your trace length, we can also estimate key electrical parameters such as resistance, voltage drop, and power loss, which are critical for efficient circuit performance.
