How big is a 24-inch 16:9 monitor? Width, height, and screen area in inches and cm
A 24-inch 16:9 monitor measures 20.92 inches wide by 11.77 inches tall, giving you about 246 square inches of screen area. This is the classic desktop size, big enough for a full-size browser window plus a sidebar, small enough to fit on almost any desk without overhang.

Note: 21:9 screens are often not exactly 21:9, but very close.
How this is calculated
In metric terms, that's 53.1 cm wide by 29.9 cm tall, or roughly 1,588 cm² of display real estate. A 24-inch panel at arm's length comfortably fills your central field of view without needing head movement. The 16:9 shape means content designed for widescreen (YouTube, Netflix, most games) maps 1:1 with no letterboxing.
Verdict
24 inches at 16:9 is the safe default for single-monitor desks under 120 cm wide. It leaves room for speakers, a laptop stand, or a second monitor later. If you have the desk space, a 27-inch 1440p panel gives you more workspace at similar physical width.
