How Screen Resolution Detection Works
Detection APIs Used
Screen Resolution = window.screen.width × window.screen.height
Viewport Size = window.innerWidth × window.innerHeight
Device Pixel Ratio = window.devicePixelRatio
Color Depth = window.screen.colorDepth (bits per pixel)Process Steps Explained
For example, if Amit in Bangalore is using a Lenovo laptop with a 1920×1080 Full HD display at 125% Windows scaling, his browser will report a screen resolution of 1536×864 CSS pixels. The device pixel ratio will be 1.25, meaning each CSS pixel maps to 1.25 physical pixels. Understanding these values is essential for web developers building responsive websites for the diverse range of devices used across India.
Practical Use Case Examples
Web Developer Testing Breakpoints
Scenario: Priya, a freelance web developer in Pune, is building an e-commerce website for a local clothing brand.
What She Checks: Viewport = 1366×625px on her laptop browser
Use Case: She confirms her CSS breakpoint at 1024px is appropriate and tests by resizing to verify the layout switches correctly for tablet users browsing on Flipkart-style layouts.
Graphic Designer Checking DPI
Scenario: Rahul in Mumbai creates social media banners for Indian startups using a MacBook Pro.
What He Checks: DPR = 2.0, Screen = 2560×1600 native
Use Case: He confirms his Retina display renders images at 2x density, so he exports banners at double resolution (2400×1260px instead of 1200×630px) for crisp quality.
Student Checking Phone Display
Scenario: Sneha in Hyderabad wants to know her Redmi Note 12 screen specs for a college presentation on mobile UX design.
What She Checks: Screen = 393×873px, DPR = 2.75, Orientation = Portrait
Use Case: She uses this data in her presentation to demonstrate why mobile-first design matters for Indian smartphone users with diverse screen sizes.
IT Support Remote Troubleshooting
Scenario: Vikram provides IT support for a company in Chennai where employees report display issues on different monitors.
What He Checks: Employee shares copied result showing 1920×1080, DPR 1.5
Use Case: He identifies the 150% scaling is causing layout issues in the company's internal dashboard and recommends resetting to 125% scaling for optimal display.
What is a Screen Resolution Checker?
A screen resolution checker is a utility tool that instantly detects and displays the technical specifications of your computer monitor, laptop screen, tablet, or smartphone display. It reveals key information including your total screen resolution in pixels, the browser viewport dimensions where web content actually renders, the device pixel ratio that determines image sharpness, your display's color depth capability, and the current screen orientation.
This tool serves a diverse audience across India and worldwide. Web developers and front-end engineers use it daily to test responsive designs and confirm that CSS media query breakpoints trigger correctly at specific viewport widths. Graphic designers rely on it to understand DPR values so they can export images at the right resolution for crisp rendering on high-DPI screens like Apple Retina displays, Samsung AMOLED panels, and other premium screens increasingly common on Indian smartphones.
Students studying web development, UI/UX design, or computer science find this tool invaluable for understanding how displays work at a technical level. IT support professionals use it to remotely diagnose display configuration issues by asking users to share their screen details. Even general users benefit when they need to verify their monitor specifications for tasks like choosing the right wallpaper size, adjusting display scaling for better readability, or confirming their screen supports the resolution needed for streaming Full HD or 4K content on platforms popular in India like YouTube, Netflix, and Disney+ Hotstar.
Built with accuracy and privacy as core principles, this tool uses standardized browser APIs that work consistently across Chrome, Firefox, Safari, Edge, and all modern browsers. Every piece of data is detected and displayed locally in your browser — nothing ever leaves your device, making it completely safe to use in professional, educational, or personal contexts.

Your privacy is fully protected. We do not use cookies, local storage, or any tracking mechanism to record your display information.
This tool uses standard browser APIs like window.screen, window.innerWidth, window.innerHeight, and window.devicePixelRatio to detect your display details. These APIs provide highly accurate information as reported by your operating system and browser. The values reflect exactly what your browser sees, including any scaling settings applied by your OS. Accuracy is consistent across Chrome, Firefox, Safari, Edge, and other modern browsers.
Screen resolution refers to the total number of pixels your entire monitor or device screen can display, such as 1920x1080. Viewport size is the area inside your browser window where web content actually appears, excluding toolbars, address bars, and scrollbars. For example, on a 1920x1080 monitor, your viewport might be 1903x937 pixels because browser chrome takes up some space. Designers use viewport size for responsive design decisions.
Device Pixel Ratio is the ratio between physical hardware pixels and CSS logical pixels on your screen. A DPR of 1 means one CSS pixel equals one hardware pixel, typical of standard monitors. A DPR of 2 means each CSS pixel is rendered using 4 physical pixels (2x2 grid), common on Retina displays and high-end smartphones. Higher DPR means sharper text and images. Most modern Indian smartphones like Samsung Galaxy or OnePlus devices have DPR of 2 to 3.
This usually happens because of display scaling settings in your operating system. Windows users often have scaling set to 125% or 150% for better readability, which makes the reported resolution appear lower than the native panel resolution. For example, a 4K monitor (3840x2160) at 150% scaling will report as 2560x1440 to browsers. MacOS Retina displays also use scaling. To see your native resolution, set scaling to 100% in your display settings.
Yes, this screen resolution checker works perfectly on all mobile phones, tablets, laptops, and desktops. It automatically detects the screen dimensions and viewport of any device you use. On mobile, you can rotate your device between portrait and landscape modes to see how the values change in real time. The tool supports Android, iOS, iPadOS, Windows, macOS, Linux, and ChromeOS devices running any modern browser.
Color depth indicates how many bits are used to represent the color of each pixel on your screen. A 24-bit color depth means your display can show approximately 16.7 million colors, which is standard for most monitors. Some high-end displays support 30-bit or 48-bit color for professional photo and video editing. Color depth matters for graphic designers, photographers, and video editors who need accurate color reproduction in their work.
Yes, web developers and designers frequently use screen resolution checkers to understand the exact viewport dimensions at different browser sizes. By resizing your browser window, you can see the live viewport width and height values update instantly. This helps you set accurate CSS media query breakpoints for responsive designs. You can also check how values differ between desktop and mobile to optimize layouts for both screen types effectively.
In India, the most popular screen resolutions as of 2024 are 1920x1080 (Full HD) for desktops and laptops, 360x800 and 393x873 for Android smartphones, and 1366x768 for budget laptops. Tablets commonly use 1280x800 or 2000x1200. With the growing adoption of smartphones from brands like Samsung, Realme, and Xiaomi, mobile resolutions are increasingly diverse, making responsive design testing essential for Indian web developers.
Yes, this tool features real-time tracking that automatically updates all viewport and window dimensions the moment you resize your browser window or rotate your device. The screen resolution and color depth remain constant since they are hardware properties, but viewport width, viewport height, and orientation values change dynamically. A live indicator shows when values are being updated so you always know the data is current.
Available screen size refers to the portion of your total screen resolution that is available for browser windows and applications, excluding operating system elements like the Windows taskbar, macOS dock, or system tray. For example, if your screen is 1920x1080 and the taskbar takes 40 pixels at the bottom, your available screen height would be 1040 pixels. This value helps developers understand the actual usable space on different devices.
