When to Use Our Free Calculator vs Altium

Use TraceWidthCalculator When:

  • You need quick trace width calculations during design review
  • You're a student or hobbyist without access to Altium
  • You're working on a Mac, Linux, or mobile device
  • You need to verify calculations from your EDA tool
  • You want instant results without software loading time

Altium Designer Is Better For:

  • Complete PCB layout and routing
  • Integrated schematic capture
  • 3D visualization and mechanical integration
  • Manufacturing file generation (Gerber, ODB++)
  • Team collaboration with Altium 365

Industry Standard Calculations

Whether you use Altium Designer or our free calculator, the underlying physics and standards are identical. Both tools implement IPC-2221 for trace width calculations and similar formulas for impedance.

The difference is accessibility: Altium requires a significant investment and Windows PC, while our calculator runs instantly in any browser. For quick calculations during design review, schematic planning, or verification, the free online tool is often faster and more convenient.

Frequently Asked Questions

Can this replace Altium Designer?

No—Altium is a complete PCB design suite for schematic capture, layout, and manufacturing. Our tool specifically replaces the trace width/impedance calculator functionality, which is often all you need for quick calculations.

Are the calculations identical to Altium?

Both tools use IPC-2221 standards, so results should be very close. Minor differences may occur due to different implementations of the empirical formulas, but typically within engineering tolerance.

Can I export results to Altium?

You can copy the calculated trace width and use it directly in your Altium design rules. We also provide a copy-to-clipboard feature for easy transfer of all calculation parameters.

Is this affiliated with Altium?

No. TraceWidthCalculator is an independent, free tool. Altium Designer is a trademark of Altium LLC. We provide this as a free alternative for basic calculations.
