About Screen Size Measurement

Screen size refers to the diagonal measurement of a display from one corner to the opposite corner. It is commonly measured in inches and used for TVs, monitors, smartphones, tablets, laptops, and projectors.

Different aspect ratios affect the actual width and height of the screen. For example, a 27-inch monitor with a 16:9 aspect ratio has different dimensions than a 27-inch ultrawide display with a 21:9 ratio.
