Accurate Pixel Measurement Tool for Web Elements and Pages - Free & Efficient!
I was looking for a reliable tool to help with my UI measurements, but this extension was a massive disappointment. First off, the user interface is incredibly unintuitive. When I opened it, I had no idea where to start or how to actually trigger the rulers. There are no clear instructions or onboarding, leaving me to click around blindly trying to figure out what I’m supposed to do. To make matters worse, it simply doesn’t function as intended. The "Inspect Mode" is buggy; it fails to accurately detect element dimensions, and the vertical/horizontal guides are clunky to move. Instead of helping me align my layout, it just added more clutter to my screen. This tool clearly lacks an understanding of what a developer actually needs in a workflow. Save yourself the headache and look for a different extension that actually works and respects the user's time.
