The 28-inch 3:2 monitor is 23.3" (59.2 cm) wide and 15.53" (39.5 cm) tall, while the 38-inch ultrawide is 34.93" (88.7 cm) wide and 14.97" (38 cm) tall. That makes the 38-inch ultrawide the larger screen by 44.5% of usable area.
The 28-inch 3:2 monitor measures 23.3" (59.2 cm) wide by 15.53" (39.5 cm) tall, with a total screen area of 361.8 square inches. The 38-inch ultrawide measures 34.93" (88.7 cm) wide by 14.97" (38 cm) tall, covering 522.8 square inches.
The practical difference: the 38-inch ultrawide is 49.9% wider, the 28-inch 3:2 monitor is 3.6% taller, and 38-inch ultrawide offers 44.5% 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 coding, timelines, spreadsheets, and games, 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.
28-inch 3:2 vs 38-inch 21:9 is mostly about side-by-side workspace. A 21:9 display behaves like one wide main workspace, while a 32:9 super ultrawide is closer to two monitors fused into one panel. The physical width number matters more than the diagonal when you are checking speakers, arms, laptop stands, or portrait side screens.
At 3840x2560, the 28-inch 3:2 monitor achieves 165 PPI. The 38-inch ultrawide at 3840x1600 reaches 109 PPI. The 28-inch 3:2 monitor has 33.6% 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.
For 16:9 content (most videos and games), the 28-inch 3:2 monitor provides an effective diagonal of 26.7", while the 38-inch ultrawide provides 30.5". Check this if you watch 16:9 video or play games that do not support ultrawide resolutions.
