Discover Page Ruler: Pixel-Perfect Webpage Measurement Tool for Designers and Developers

Need to measure exact pixel dimensions of webpage elements, check spacing between components, or verify layout specifications? Meet Page Ruler - a powerful Chrome extension that transforms your browser into a precision measurement tool. Whether you're a web designer verifying mockups, a developer debugging layouts, or a QA tester checking pixel-perfect implementations, Page Ruler provides the exact measurements you need with an intuitive, real-time ruler interface.

What is Page Ruler?

Page Ruler is a sophisticated Chrome extension that creates an interactive measurement overlay on any webpage, allowing you to measure distances, dimensions, and spacing with pixel-perfect accuracy.
