The 29-inch ultrawide is 26.66" (67.7 cm) wide and 11.42" (29 cm) tall, while the 65-inch monitor is 56.65" (143.9 cm) wide and 31.87" (80.9 cm) tall. That makes the 65-inch monitor the larger screen by 492.9% of usable area.
The 29-inch ultrawide measures 26.66" (67.7 cm) wide by 11.42" (29 cm) tall, with a total screen area of 304.5 square inches. The 65-inch monitor measures 56.65" (143.9 cm) wide by 31.87" (80.9 cm) tall, covering 1805.3 square inches.
The practical difference: the 65-inch monitor is 112.5% wider, the 65-inch monitor is 179% taller, and 65-inch monitor offers 492.9% 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.
29-inch 21:9 vs 65-inch 16:9 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 2560x1080, the 29-inch ultrawide achieves 96 PPI. The 65-inch monitor at 3840x2160 reaches 68 PPI. The 29-inch ultrawide has 29.3% 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 29-inch ultrawide provides an effective diagonal of 23.3", while the 65-inch monitor provides 65". Check this if you watch 16:9 video or play games that do not support ultrawide resolutions.
