15-inch (38.1 cm) monitor dimensions

A 15-inch display changes shape depending on aspect ratio. Use these measured dimensions to estimate desk fit, screen area, and adjacent-size or ultrawide alternatives.

A 15-inch 16:9 monitor is about 13.1 inches wide and 7.4 inches tall, before bezels or the stand. To fill a relaxed 30-degree view, sit about 24 inches (61 cm) away; about 18 inches (46 cm) fills an immersive 40 degrees. At this size, the useful comparison is not raw desk width; it is how the small screen scales beside a 24, 27, or 32-inch desktop monitor.
