28-inch (71.1 cm) monitor dimensions
A 28-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 28-inch 16:9 monitor is about 24.4 inches (62 cm) wide and 13.7 inches (34.9 cm) tall, before bezels or the stand. The 28-inch monitors in our product catalog are not 16:9, though: the BenQ RD280U Programming Monitor is 3:2 (23.5 x 15.6 in) and the LG DualUp 28MQ780-B is 16:18 (18.3 x 20.6 in). Pick the shape first; the diagonal barely separates them.
