Frequently Asked Questions ❓

Got questions? We've got answers

Which browsers are supported?

Web Design Ruler works with Google Chrome, Firefox, and Chromium-based browsers like Microsoft Edge, Brave, Opera, and Vivaldi. Install from the Chrome Web Store, Firefox Add-ons, or download the extension files directly.

Is Web Design Ruler free to use?

Yes! Web Design Ruler is completely free to use. We created it to simplify web design workflows and give back to the design community.

Can I use the extension on any website?

Yes, you can use Web Design Ruler on any website. However, it cannot be used on browser pages like the Chrome Web Store, Settings, or New Tab page due to Chrome's security restrictions.

Why is it distributed as an unpacked extension?

We offer both options! You can install from official stores (Chrome Web Store and Firefox Add-ons) or download it as an unpacked extension for those who prefer manual installation or want to inspect the code.

Why can't I delete the extension folder?

Chrome loads unpacked extensions directly from the folder location you specify during installation. If you delete or move this folder, Chrome can no longer find the extension files, and it will stop working. This is different from extensions installed from the Chrome Web Store, which are stored in Chrome's internal storage.

How accurate are the measurements?

The measurement tool provides pixel-perfect accuracy based on the rendered elements in the browser. It measures exactly what you see on screen.

Can it identify all fonts?

The font detector can identify any font that's actively loaded and applied to text on the webpage. It cannot identify fonts in images or custom fonts that use non-standard loading methods.
