Why Switch from EEWeb?
Modern Interface
EEWeb's calculator has a dated design with cluttered layouts. Our tool features a clean, modern dark-mode interface that's easier to read and use, especially in lab environments.
No Advertisements
EEWeb displays numerous ads that slow page loading and distract from calculations. TraceWidthCalculator is completely ad-free for an uninterrupted engineering experience.
Mobile First
EEWeb wasn't designed for mobile devices. Our responsive design works perfectly on phones and tablets—essential for checking calculations during board reviews or in the lab.
Features EEWeb Doesn't Have
Via Current Calculator
Design thermal via arrays and calculate PTH current capacity. Essential for power electronics and high-current designs that EEWeb's basic calculators can't handle.
Differential Impedance
Calculate coupled differential pairs for USB, HDMI, and high-speed digital interfaces. Modern PCB designs require this capability that EEWeb doesn't provide.
About EEWeb
EEWeb has been a popular electronics engineering resource for many years, offering various calculators and tools for PCB design. Their trace width calculator has helped many engineers with basic IPC-2221 calculations.
However, the site's design hasn't kept pace with modern web standards. Heavy advertising, limited mobile support, and an outdated interface can make the experience frustrating for engineers who need quick, reliable calculations.
TraceWidthCalculator offers a modern alternative with the same accurate IPC-2221 calculations in a cleaner, faster, more capable package.
Same Standards, Better Experience
Try the Modern Alternative
Same IPC-2221 accuracy as EEWeb with a modern interface, no ads, and additional features. Start calculating immediately.
Frequently Asked Questions
Are the results the same as EEWeb?
Yes. Both calculators use IPC-2221 standards. Results should be identical for the same input parameters.
Why is this better than EEWeb?
Modern interface, no ads, mobile support, and additional tools like via current calculator. Same accuracy, better experience.
Is EEWeb going away?
EEWeb is still available. We offer an alternative for engineers who prefer a modern, ad-free experience.
Is this affiliated with EEWeb?
No. TraceWidthCalculator is an independent, free tool. EEWeb is a separate website and trademark.
