27-inch (68.6 cm) monitor dimensions
A 27-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 27-inch 16:9 monitor is about 23.5 inches wide and 13.2 inches tall, before bezels or the stand. To fill a relaxed 30-degree view, sit about 44 inches (112 cm) away; about 32 inches (81 cm) fills an immersive 40 degrees. Compare the 16:9 row against ultrawide and taller aspect ratios before deciding whether you need more width, more height, or sharper text.
