Discover your current screen resolution, color depth, and other display properties. This information is useful for web development, graphic design, and optimizing your display settings.
Note: This tool detects your screen resolution in real-time. The values update automatically when you resize your browser window.
You sit down at your computer, perhaps to watch a movie, design a website, or simply browse the web. Have you ever stopped to consider the canvas you’re looking at? The clarity of the text, the sharpness of the images, and the amount of content you can see at once are all dictated by one fundamental setting: your screen resolution.
The question “What is my screen resolution?” is more than a technical curiosity. It’s the first step toward optimizing everything you do on your device, from everyday browsing to professional creative work. Our simple, instant tool gives you this vital piece of information, empowering you to take control of your digital view. But knowing your resolution is just the beginning; understanding its implications is where the real power lies.
In simple terms, your screen resolution is the number of distinct pixels that can be displayed in each dimension on your screen. It is typically written as Width x Height. For example, a common resolution is 1920 x 1080. This means the screen displays 1,920 pixels horizontally and 1,080 pixels vertically, for a total of over 2 million individual points of light.
It’s crucial to distinguish between resolution and screen size. Screen size is the physical measurement of your display, diagonally, in inches. Resolution is the density of the pixels on that physical screen. A 24-inch monitor and a 15-inch laptop can both have a 1920×1080 resolution, but the image will appear sharper on the laptop because the pixels are packed more tightly (resulting in a higher Pixels Per Inch, or PPI).
You might be surprised how often this information is useful.
Troubleshooting Display Issues: Is an application window too large for your screen? Is text appearing blurry? Knowing your native resolution is the first step in diagnosing these problems. Your display should typically be set to its “recommended” or “native” resolution for the sharpest image.
Online Shopping and Product Listings: When shopping for a new monitor, laptop, or even a smartphone, understanding resolution helps you make an informed decision. You’ll know the difference between HD (1280×720), Full HD (1920×1080), QHD (2560×1440), and 4K UHD (3840×2160).
Gaming Performance: For PC gamers, resolution is a critical setting. Higher resolutions offer stunning visual fidelity but demand significantly more power from your graphics card. Knowing your monitor’s maximum resolution allows you to balance visual quality and performance in game settings.
Software and Application Setup: Many professional applications for photo editing, video production, and 3D modeling have interfaces and tools that are affected by your available screen space. Knowing your resolution helps you configure your workspace efficiently.
While a user might ask “What is my screen resolution?” to solve a personal display issue, a website owner or developer asks this question to solve problems for thousands of users at once. This is where our tool becomes part of a powerful diagnostic suite for maintaining a healthy, user-friendly website.
You receive feedback that your website looks “broken” on some devices. Your first instinct might be to check it on your own phone, but what about the thousands of other screen sizes out there?
Our Website Screenshot Generator is the perfect companion here. After using the “What is My Screen Resolution” tool to understand your own device, you can use the screenshot tool to see your website from dozens of different perspectives. Generate screenshots for common resolutions like 360×640 (mobile), 768×1024 (tablet), and 1366×768 (small laptop). This allows you to visually audit your site’s responsive design and catch layout issues that you would never see on your own machine.
Your analytics show a sudden, unexplained drop in traffic. Before blaming your content, a savvy webmaster investigates technical causes. One possibility is that your site has been compromised and is serving malware, causing browsers and search engines to block it.
This is where our Online Virus Scanner becomes your first line of defense. By running your website’s URL through the scanner, you can quickly rule out a security breach as the cause of your traffic problems. A clean bill of health from the scanner allows you to focus your investigation elsewhere, saving valuable time.
Your website seems slow, especially for users on their first visit. You’ve been told that enabling browser caching for static resources like images and CSS can help, but you’re not sure if it’s working correctly.
Our HTTP Headers Checker provides the answer. This tool inspects the hidden technical messages your web server sends to a browser. After configuring your cache settings, you can use this tool to check for headers like Cache-Control and ETag. Confirming these headers are present and correctly configured ensures that returning visitors experience a much faster-loading site. It’s a technical fix that has a direct, positive impact on user experience across all screen resolutions.
For web designers and developers, the question “What is my screen resolution?” is asked constantly, but for a different reason. They are tasked with creating a single website that must look and function perfectly on an nearly infinite variety of screen sizes and resolutions.
This practice is called Responsive Web Design (RWD). It uses flexible grids, fluid images, and CSS media queries to automatically adjust the layout of a website based on the screen size of the device viewing it. The goal is to provide an optimal experience for everyone, from a user with a large 4K desktop monitor to someone browsing on a small smartphone.
When you use our “What is My Screen Resolution” tool as a developer, you are taking a sample of one from a vast ocean of possibilities. It’s a reminder of the diversity of your audience and the importance of building websites that are flexible and resilient, not fixed and fragile.
On Windows:
Right-click on your desktop and select “Display settings.”
Scroll down to “Display resolution.”
Use the dropdown menu to select the resolution marked “(Recommended).”
On macOS:
Click the Apple menu and go to “System Settings” > “Displays.”
Here you can see your current resolution and choose a different “Resolution” setting, with “Default for display” usually being the best choice.
The answer to “What is my screen resolution?” is a gateway to a deeper understanding of your digital environment. For the everyday user, it empowers better purchasing decisions and troubleshooting. For the website creator, it is a fundamental data point that underscores the critical importance of building responsive, fast, and secure websites for a global audience.
By combining the simple insight from this tool with the diagnostic power of a Website Screenshot Generator, the security assurance of an Online Virus Scanner, and the technical validation of an HTTP Headers Checker, you can ensure that your corner of the internet is accessible and enjoyable for every visitor, no matter what screen they’re using.
