The 27-inch monitor is 23.53" (59.8 cm) wide and 13.24" (33.6 cm) tall, while the 28-inch 3:2 monitor is 23.3" (59.2 cm) wide and 15.53" (39.5 cm) tall. That makes the 28-inch 3:2 monitor the larger screen by 16.2% of usable area.

The 27-inch monitor measures 23.53" (59.8 cm) wide by 13.24" (33.6 cm) tall, with a total screen area of 311.5 square inches. The 28-inch 3:2 monitor measures 23.3" (59.2 cm) wide by 15.53" (39.5 cm) tall, covering 361.8 square inches.

The practical difference: the 27-inch monitor is 1% wider, the 28-inch 3:2 monitor is 17.3% taller, and 28-inch 3:2 monitor offers 16.2% more screen area. Width affects how much desk space you need, while the height delta shows how much vertical space changes for documents, timelines, and video.

The practical choice depends on what feels limiting in your current setup. For desk fit, text size, coding, office work, and gaming, the wider option gives more room for side-by-side windows, while the taller option keeps more vertical content visible without pushing the edges of the screen as far away. If your desk is shallow, width and viewing distance matter as much as raw diagonal size.

At 3840x2160, the 27-inch monitor achieves 163 PPI. The 28-inch 3:2 monitor at 3840x2560 reaches 165 PPI. The 28-inch 3:2 monitor has 1% higher pixel density, resulting in sharper text and images.

For text-heavy work, PPI is the number that decides whether you are buying more room or just making everything bigger. A lower-PPI large screen can feel spacious for windows but softer for code and documents. A higher-PPI screen may need OS scaling, but it usually gives cleaner text and more flexible sizing.
