Trace Width Calculator

Welcome to our Trace Width Calculator, designed to help determine the optimal width for PCB traces based on specific operational parameters. This tool calculates the minimum required trace width to safely conduct a given amount of current, considering factors like copper thickness, trace length, temperature rise, and whether the trace is internal or external.

Inputs Required:

  • Current (Amps)
  • Thickness (oz/ft², mils, mm, µm)
  • Temperature Rise (°C)
  • Trace Length (mils, cm, mm, µm, in)
  • Layer Type (Internal or External)

Outputs Provided:

  • Required Trace Width (mm and mils)
  • Resistance (Ohms)
  • Voltage Drop (Volts)
  • Power Loss (Watts)

Disclaimer:
Please note that the results provided by this calculator are for estimation purposes only and should be used as a guide during the design process. We make every effort to ensure the accuracy of this tool, but it is important to verify all calculations through standard design verification processes. We are not liable for any errors in calculations or their consequences in your projects.
