How to Check Your Screen Resolution
Your screen resolution is the number of pixels your display shows horizontally and vertically (e.g. 1920×1080). Below are the fastest ways to find it on every major platform.
1. The fastest way — any device
Open the screen resolution detector. Your width × height appears at the top of the page within a second, along with aspect ratio, estimated DPI, and viewport size. Works on Windows, macOS, Linux, iPhone, iPad, Android, and Chromebooks — no install required.
2. Windows 10 and Windows 11
Right-click anywhere on the desktop and choose Display settings. Scroll down to Display resolution — the value labeled (Recommended) is your native screen resolution.
3. macOS (Sonoma, Sequoia, Tahoe)
Click the Apple menu → System Settings → Displays. Hover the resolution thumbnails — macOS shows the pixel dimensions for each scaling option. The “Default” choice corresponds to the display's native resolution.
4. iPhone and iPad
iOS does not show the screen resolution in Settings. The easiest path is the online detector above, which reads your device's actual screen dimensions through the browser.
5. Android
On most Android phones: Settings → Display → Screen resolution. If your phone hides the option (common on mid-range devices), use the online detector — it reports the value directly.
6. Chromebook
Open Settings → Device → Displays and look at Display size. The first entry under Resolution is native.
7. Linux (GNOME / KDE)
GNOME: Settings → Displays. KDE Plasma: System Settings → Display and Monitor. Both list the current resolution next to each connected display.
