About Monitor sizes
Desktop monitor sizes from 19 to 49 inches, including 16:9, 21:9 and 32:9 formats.
Screen size is the diagonal length in inches, not the width. A 55-inch TV measures about 122 × 69 cm.
The same diagonal with a different aspect ratio gives different width and height; 16:9 is standard for TVs and monitors, while phones and tablets vary.
