Measure DPR for high density screens, Retina displays, mobile devices, tablets, laptops, and external monitors.
Color and Orientation
Read color depth, pixel depth, available screen area, and landscape or portrait orientation from your current browser.
Free Screen Resolution Checker Online
If you are asking what is my screen resolution, this page gives you a direct answer without installing software. The detector reads your display size in pixels and updates when you resize the browser window, rotate a mobile device, connect another monitor, or change zoom settings.
Screen resolution is the full pixel width and height of your physical display. Browser viewport size is the visible page area inside the browser. That difference matters for web design, responsive testing, screenshot preparation, video recording, gaming, troubleshooting, and checking monitor settings.
The screen size checker works on desktop computers, laptops, tablets, phones, Chromebooks, ultrawide monitors, 4K monitors, high DPI screens, and common mobile browsers. It does not ask for personal information, account access, downloads, or browser extensions.
Use the results to compare HD, Full HD, QHD, WQHD, 4K UHD, 5K, ultrawide, tablet, and mobile screen resolutions. You can also copy the result when you need to share your monitor resolution with a developer, designer, support team, or client.
Common Screen Resolutions
Compare your result with common display resolution names used for laptops, desktop monitors, mobile devices, tablets, TVs, and web design breakpoints.
| Resolution | Common Name | Typical Use | Aspect Ratio |
|---|---|---|---|
| 1366 x 768 | HD laptop | Entry level laptops, older notebooks, compact displays | 16:9 |
| 1920 x 1080 | Full HD or 1080p | Common desktop monitors, laptops, streaming, gaming, screenshots | 16:9 |
| 2560 x 1440 | QHD or 1440p | High detail monitors, design work, productivity, gaming | 16:9 |
| 3440 x 1440 | Ultrawide QHD | Wide monitors, multitasking, timelines, dashboards, games | 21:9 |
| 3840 x 2160 | 4K UHD | 4K monitors, TVs, video editing, high resolution screenshots | 16:9 |
Your browser may report a viewport size that is smaller than these numbers because browser controls, operating system bars, zoom level, and split screen modes reduce the visible page area.
How to Check My Screen Resolution
The checker runs in your browser and uses standard display properties, so it works without a download on most modern devices.
Open the Checker
Load the page on the device or monitor you want to test. The main result shows your current screen resolution in pixels.
Read the Details
Use the cards to compare screen width, screen height, browser viewport, available display area, DPR, color depth, and aspect ratio.
Refresh or Copy
Resize the window or rotate the device, then refresh the result or copy the display details for support, design, development, or testing.
Screen Resolution FAQ
What is my screen resolution?
Your screen resolution is the width and height of your display in pixels. A common example is 1920 x 1080, which means 1920 pixels wide and 1080 pixels tall.
What is the difference between screen resolution and browser viewport size?
The viewport only measures the visible web page area inside the browser. Browser tabs, toolbars, side panels, and operating system bars reduce the available page area.
How do I find my monitor resolution online?
Open this page and read the main result at the top. It shows your current monitor resolution or device display resolution in pixels.
Does this screen resolution checker work on mobile?
Yes. The checker works on desktop, laptop, tablet, and mobile browsers that support standard screen and window properties.
What does device pixel ratio mean?
Device pixel ratio compares CSS pixels to physical display pixels. High density screens often use a ratio above 1, which makes text and interface elements look sharper.
Why does my display resolution change after zooming?
Browser zoom can change viewport and CSS pixel calculations. The physical screen resolution normally stays the same, but the browser may report a different visible page size.
