Frequently Asked Questions
Screen resolution refers to the number of pixels your screen can display, expressed as width × height (e.g., 1920×1080).
Resolution is the number of pixels, while physical size is the actual measured dimensions of your screen.
Pixel density measures how many pixels fit in one inch of your screen. Higher numbers mean sharper displays.
Aspect ratio is the proportional relationship between width and height, commonly expressed as 16:9 for modern displays.
Screen dimensions and orientation update automatically to reflect your device's current position.
The estimation is based on your device's reported specifications and may vary slightly from actual measurements.
