What is a PCB trace width calculator?

A PCB trace width calculator is a tool that helps engineers determine the minimum required width for copper traces on printed circuit boards based on current capacity, temperature rise, and copper thickness.

Which standards does this calculator use?

This calculator uses both IPC-2152 (the current standard) and IPC-2221 (the previous standard) for calculating trace widths, allowing you to choose based on your requirements.

Is this trace width calculator free to use?

Yes, the basic trace width calculator is completely free to use. Premium features like unlimited PDF exports and batch calculations are available with a professional subscription.
