Screen Resolution Test
Check your screen dimensions and get wallpaper recommendations
My Screen Resolution is:
-
Aspect Ratio
-
The proportional relationship between width and height, which determines the screen shape. Device Pixel Ratio (DPR) tells you how many device pixels equal one CSS pixel (e.g., DPR 2 means each CSS pixel uses a 2×2 grid of device pixels).
Viewport Size
-
Current browser window dimensions, these change when you resize your browser.
Color Depth
-
Bits per pixel for color representation, higher values mean more colors and better image quality.
Pixel Density
-
Device pixel ratio, higher values indicate high DPI displays like Retina screens. High-DPI screens look sharper because they pack more physical pixels into the same CSS size.

-
Total Pixels
The complete number of individual pixels on your screen. Higher pixel counts provide sharper images and more screen real estate for productivity and gaming. DPR vs. Physical Pixels: Your browser lays out pages in CSS pixels, which are virtual units. Displays render with device (physical) pixels—the actual dots on your panel.
-
Orientation
Screen orientation determines whether your display is wider than it is tall or taller than it is wide. Most desktop monitors use landscape orientation.
-
Display Type
Display classification based on resolution and pixel density. Higher classifications like 4K and Retina offer superior image quality and clarity.
-
Best Wallpaper Size
Recommended wallpaper resolution for optimal image quality. Matching or exceeding your screen resolution ensures crisp, detailed backgrounds. Our tester shows your physical resolution (CSS size × DPR, adjusted for zoom) so you can pick wallpaper sizes and assets that look perfectly crisp.

Want a sharper display or more workspace? Change Your Resolution (Windows & macOS)
On Windows 11/10, go to Settings → System → Display → Display resolution, pick a size, then Keep changes. You can also adjust Scale for text and apps, and check Advanced display for refresh rate options.
On macOS (Sonoma/Ventura), open System Settings → Displays and choose a Scaled option (use More Space for a larger desktop).
On older Macs (System Preferences → Displays), hold Option while clicking Scaled to reveal all resolutions.
Tip: match your monitor’s native resolution for the best clarity; use scaling if text looks too small.
