Use this free screen resolution checker to find out what resolution your screen is running right now. Open this page on any device and your resolution appears instantly, no software to install and no account needed. Unlike most tools that only show your actual screen resolution, this screen resolution checker also shows your available resolution, which updates in real time as you resize the browser window. Works on phones, tablets, laptops, and desktops.
Your screen resolution is the number of pixels displayed on your screen, expressed as width x height. A resolution of 1920 x 1080 means your screen is 1,920 pixels wide and 1,080 pixels tall, which is over 2 million individual pixels rendering everything you see.
Resolution matters because it directly affects how sharp text and images look, how much content you can fit on screen at once, and how demanding your display is on your device's graphics processor. Higher resolution means more detail, but also more processing work.
There are two resolution values worth knowing about:
Most tools only show the first. This one shows both.
The fastest way to check screen resolution is to use the tool at the top of this page. It reads your display settings the moment the page loads and shows the result without you having to do anything. If you prefer to check through your operating system settings directly, here is how:
Not sure what your numbers mean? This table covers the most common screen resolutions you will encounter in 2025 and what devices typically use them.
| Resolution | Name | Common Devices | Share of Web Users (approx.) |
|---|---|---|---|
| 1920 x 1080 | Full HD (1080p) | Most desktop monitors, mid-range laptops | ~35-40% |
| 1366 x 768 | HD | Budget laptops, older screens | ~10-15% |
| 2560 x 1440 | QHD / 2K | High-end monitors, gaming setups, MacBook Pro | ~7-10% |
| 3840 x 2160 | 4K / UHD | Premium monitors, some modern laptops | ~5-8% (growing) |
| 1280 x 800 | WXGA | Older MacBooks, budget tablets | ~3-5% |
| 2560 x 1600 | WQXGA | MacBook Pro 14-inch and 16-inch (Retina) | ~2-4% |
| 390 x 844 | iPhone viewport | iPhone 14 / 15 (CSS pixels) | Mobile varies widely |
| 360 x 800 | Android viewport | Common Android phones (CSS pixels) | Mobile varies widely |
Web developers should test designs at a minimum of 1366 x 768, 1920 x 1080, and at least one mobile viewport to cover the vast majority of their audience. The old baseline of 1024 x 768 is no longer relevant for most sites.
Gaming resolution has a direct impact on both visual quality and performance. The three main options most PC gamers choose between are:
For competitive multiplayer games, many players actually run at 1080p even on a 1440p monitor, because the performance boost is worth more than the extra sharpness. Use this tool to confirm what resolution your monitor is currently set to before adjusting in-game settings.
Color accuracy and screen real estate both matter for creative work. A 1080p display is workable but limits how much of an image or timeline you can see at once. Most professional photo editors prefer at least 1440p, and 4K is increasingly common in editing suites because it allows you to view large images at 1:1 pixel ratio without scrolling.
For video editing, a 4K display lets you preview 4K footage at actual resolution, which is helpful for checking sharpness and detail. If your display is only 1080p, a 4K video preview is scaled down and you will miss pixel-level issues until export.
Knowing your own screen resolution is the starting point for responsive design work. When you build a layout at 1920 x 1080 and then check it on a 1366 x 768 display, you often find content that overflows or columns that collapse unexpectedly.
A few practical rules for web development:
If you are checking what theme or platform a website uses as part of your research, you can use the CMS detector alongside this tool for a complete picture of the site's technical setup.
Resolution and pixel density are related but not the same thing. Resolution is the total pixel count. Pixel density, measured in pixels per inch (PPI), tells you how tightly those pixels are packed together.
A 27-inch 4K monitor has roughly 163 PPI. A 15-inch laptop with the same 4K resolution has roughly 294 PPI because the same number of pixels are packed into a smaller space. The laptop screen looks noticeably sharper even though the resolution is identical.
This is why a phone with 2778 x 1284 resolution can look far sharper than a desktop monitor with what appears to be a higher pixel count. When comparing sharpness across devices, PPI matters as much as raw resolution numbers. Apple calls high-density displays Retina (typically 220 PPI or above). Other manufacturers use terms like QHD+ or Super AMOLED to indicate high pixel density.
A key detail: phones report a high physical resolution (for example, 2556 x 1179 on an iPhone 15 Pro) but browsers treat them at a lower logical resolution (393 x 852) to keep text readable. This tool shows the logical resolution your browser uses, which is the value that matters for web design.
On Windows 11, right-click anywhere on the desktop and choose Display settings. Scroll down to the Display resolution section and click the dropdown to see all supported resolutions for your monitor. Select the one you want, then click Keep changes when prompted. Windows recommends the native resolution for your display, marked as Recommended in the list. Changing to a non-native resolution will make the display appear softer or scaled.
On a Mac running macOS Ventura or later, open System Settings from the Apple menu, then click Displays. You will see your current resolution and a set of scaled options. Holding the Option key while clicking Scaled reveals additional resolution options that Apple hides by default. Select your preferred resolution and the change applies immediately without a restart.
On older Macs running macOS Monterey or earlier, the path is System Preferences, then Displays, then click Scaled and hold Option for additional options.
Yes, completely free. There is no account, no download, and no limit on how many times you use it. Open the page on any device and your resolution appears immediately. You can check multiple devices by opening this page in separate browser tabs or on different devices at the same time.
Very accurate. The tool reads your display dimensions directly from the browser's built-in JavaScript APIs, which report the same values your operating system uses. This makes it a reliable display resolution test for any device with a browser. The available resolution updates live as you resize the window, so you can watch the numbers change in real time if you want to see your available workspace at different browser sizes.
Yes, in several ways. At lower resolutions, websites may appear larger and require horizontal scrolling if the site is not responsive. At higher resolutions, pages show more content above the fold, which affects where users focus and how they interact with your layout.
For streaming, most services detect your display resolution and adjust video quality automatically. A 4K display will receive 4K streams when your connection supports it. Gaming is the most resolution-sensitive use case: running a game at a higher resolution than your GPU can handle drops frame rates significantly.
Your screen resolution is one of those settings most people ignore until something looks wrong. Use this screen resolution checker to see yours in one click, then use that number to make better decisions about gaming settings, web design breakpoints, monitor upgrades, and image sizing.
