My Screen Resolution

Instantly display your screen resolution, viewport size, pixel ratio and color depth.

MY SCREEN RESOLUTION — Instant Display Info for Developers & Designers Knowing your screen resolution is one of the most basic pieces of information a web developer or designer needs. Whether you are testing responsive breakpoints, debugging a layout issue, or documenting your hardware configuration, having a screen resolution tool that is always one click away makes your workflow smoother. This extension shows your screen resolution, viewport size, pixel ratio, available screen area, and color depth instantly — right in your browser toolbar. WHY CHECK YOUR SCREEN RESOLUTION WITH THIS EXTENSION? Most developers check their screen resolution by digging through operating system settings, which takes several clicks and navigation steps. This extension shows your screen resolution in under one second. Click the toolbar icon and every display metric you need appears immediately, without opening a single system panel or external website. For web developers, knowing the viewport alongside the screen resolution matters just as much as the raw display size. A user's browser may be windowed, or their OS may use display scaling, meaning the CSS viewport is different from the physical screen resolution. This extension shows both values side by side so you always have the full picture. KEY FEATURES 🖥️ Screen Resolution Display — See your full display dimensions (width × height) in a large, easy-to-read format at the top of the popup. The screen resolution updates automatically each time you open the extension. 📐 Available Screen Area — Shows the available screen resolution minus space used by the OS taskbar, dock, or system UI. This is the usable area your browser windows actually occupy. 🎨 Color Depth — Displays the bit depth of your screen's color output. Standard displays show 24-bit; most modern displays with wide color support show 30-bit or higher. 🔍 Device Pixel Ratio — Reports the DPR value, which tells you whether you are on a standard display (1×) or a high-density Retina or HiDPI display (1.5×, 2×, 3×, and beyond). 📏 Viewport Size — Shows the current inner width and height of the browser viewport. Useful for checking exact breakpoint behavior when your browser is in a non-maximized state. 📋 Copy to Clipboard — The "Copy Resolution" button copies your screen resolution in the format 1920x1080 directly to your clipboard with one click, confirming with a brief "Copied!" message. 🌍 33 Languages Supported — The screen resolution display interface is fully localized for 33 languages including English, Russian, German, French, Spanish, Japanese, Chinese, Arabic, and more. 🔒 Fully Offline and Private — No permissions required. The extension does not access any browser tabs, connect to the internet, or store any data. Display values are read directly from browser APIs without leaving your device. HOW TO USE 1. Click the screen resolution icon in your Chrome toolbar. 2. Read your screen resolution instantly from the large display at the top. 3. Check available screen area, color depth, pixel ratio, and viewport size in the details panel. 4. Click "Copy Resolution" to copy the screen resolution to your clipboard. 5. Paste the resolution value wherever you need it — bug reports, documentation, Slack messages. WHO USES THIS EXTENSION? Web developers verify how responsive layouts behave at the exact display size of their test machine. Designers match mockup canvas sizes to real screen dimensions. QA engineers document screen resolution and DPR as part of bug reports. IT administrators confirm display configuration on managed devices. Remote workers track display specs when switching between office monitors, laptops, and external displays. ACCURACY All values come directly from the browser's own APIs: window.screen.width/height, availWidth/availHeight, colorDepth, devicePixelRatio, and innerWidth/innerHeight. The display values shown are identical to what the operating system reports to the browser. PRIVACY This screen resolution extension requires no permissions at all. It reads only the values exposed by standard browser APIs within the popup's own window context. It does not access any open tabs, does not communicate with any servers, and does not log or store anything. The extension is completely self-contained. Get your screen resolution at a glance — one click, zero friction, total privacy.
