Display
Aspect Ratio
The ratio of screen width to height (e.g., 19.5:9, 16:10); affects how tall or wide a screen feels.
Full Definition & Technical Explanation
Aspect ratio is the width-to-height relationship of a display. Phones use tall ratios like 19.5:9 or 20:9 for one-hand use; laptops commonly use 16:9 (media) or 16:10/3:2 (productivity).
See Aspect ratio: 19.5:9 in display specs. Taller ratios mean more vertical content without widening the device.
