WhatIsMyScreenResolution.org is an online tool that can be used to check the screen resolution of any display device, including Android, Windows Desktop, iPad, Tablet, iPhone, MacBook, and more.
When you visit our website your current screen resolution will be displayed automatically.
This website is designed to help you quickly and easily get your Screen Resolution size for a variety of purposes. Whether you're a web designer, photographer, gamer, or trying to figure out how long your device screen size is in height and width, our Display Resolution detector can help.
Screen resolution is the number of pixels in a display, measured in width x height. For example, a screen resolution of 1920 x 1080 means that the display has 1920 pixels horizontally and 1080 pixels vertically.
Screen resolution, device resolution and browser viewport
Three different measurements all get called "resolution", and mixing them up is the most common reason a reading looks wrong. The table above reports all three separately:
- Device Resolution — the real, physical pixels built into the panel. A 4K monitor has 3840 x 2160 of them however it is configured.
- Screen resolution — what web pages are laid out in. On a high-density display the system packs several device pixels into each one so text stays readable. The multiplier is the DPR.
- Browser Viewport — the part of the window a page can actually draw into, after the address bar, tabs and taskbar take their share.
Multiply the screen resolution by the DPR and you get the device resolution back. A MacBook reporting 1512 x 982 at a DPR of 2 has a 3024 x 1964 panel — which is why the figure can look far lower than the specification you bought.
Common screen resolutions
| Name | Resolution | Aspect | Typically found on |
|---|---|---|---|
| HD (720p) | 1280 x 720 | 16:9 | Budget laptops, older TVs |
| HD+ | 1600 x 900 | 16:9 | Older 20-inch monitors |
| Full HD (1080p) | 1920 x 1080 | 16:9 | The most common desktop resolution |
| WUXGA | 1920 x 1200 | 16:10 | Productivity monitors, many laptops |
| QHD (1440p) | 2560 x 1440 | 16:9 | 27-inch and gaming monitors |
| Ultra-wide QHD | 3440 x 1440 | 21:9 | 34-inch ultra-wide monitors |
| 4K UHD | 3840 x 2160 | 16:9 | 32-inch monitors, modern TVs |
| 5K | 5120 x 2880 | 16:9 | 27-inch Retina displays |
| 8K UHD | 7680 x 4320 | 16:9 | High-end televisions |
How to change your screen resolution
If the reading above is lower than your display supports, the system is driving the panel below its native resolution, which almost always looks soft because the image has to be stretched. Setting it back to native fixes it:
- Windows — Settings → System → Display → Display resolution, and choose the entry marked "Recommended". how to check or change Windows screen resolution.
- macOS — System Settings → Displays, then Default for display. how to check or change macOS screen resolution.
- Android and iPhone — resolution is fixed by the hardware; what you can change is display size or zoom, which alters the reported figure but not the panel.
Measuring the screen itself
Pixels describe the grid, not how large it is in the real world. For physical dimensions, work out inches and pixel density from your diagonal with the monitor size calculator, or measure something directly on the glass with the online screen ruler.

Frequently asked questions
What is my screen resolution right now?
The figure at the top of this page is your live screen resolution, read straight from your browser. It is the number of pixels your display shows horizontally by the number it shows vertically — for example 1920 x 1080. Nothing is uploaded; the reading is taken on your own device.
Why is my screen resolution different from what I bought?
Two things usually explain it. First, the operating system may be running the panel below its native resolution. Second, on high-density screens the browser reports CSS pixels rather than physical pixels — a 2560 x 1440 laptop scaled at 200% reports 1280 x 720. Multiply by the device pixel ratio to recover the physical figure, shown above as Device Resolution.
What is the difference between screen resolution and browser viewport?
Screen resolution describes the whole display. The browser viewport is only the area a web page can draw into, so it excludes the address bar, tabs, bookmarks bar and the operating-system taskbar. The viewport is always smaller, and it is the number that matters when testing a responsive layout.
Does screen resolution change when I resize the browser?
No. Resizing changes the viewport but never the screen resolution — the display still has the same pixel grid. Watch the diagram above as you resize: the outer screen stays fixed while the viewport inset moves.
What is a good screen resolution?
For a desktop monitor up to about 24 inches, 1920 x 1080 is comfortable. From 27 inches upward 2560 x 1440 keeps text sharp, and 3840 x 2160 (4K) suits 32-inch panels. What matters more than the raw number is pixel density — pixels per inch — which the monitor size tool works out for you.
Is this screen resolution test accurate?
The pixel figures are exact, because they come from the browser rather than a guess. Measurements in inches are the estimated part: a browser is not told the physical size of your panel, so the screen diagonal is derived from the standard 96 pixels-per-inch reference.
