Displays an overlay with viewport dimensions and aspect ratio. The Viewport Dimension Overlay is a handy Chrome extension that helps web developers and designers by displaying a clean, unobtrusive overlay showing real-time viewport dimensions and aspect ratio of any webpage. With a simple click, users can toggle an elegant semi-transparent overlay that appears in the bottom-right corner, providing instant feedback about the current window size and automatically updating as the browser window is resized. This makes it an invaluable tool for responsive design testing and layout debugging.
