The 49-inch super ultrawide is 47.17" (119.8 cm) wide and 13.27" (33.7 cm) tall, while the 70-inch monitor is 61.01" (155 cm) wide and 34.32" (87.2 cm) tall. That makes the 70-inch monitor the larger screen by 234.6% of usable area.
The 49-inch super ultrawide measures 47.17" (119.8 cm) wide by 13.27" (33.7 cm) tall, with a total screen area of 625.8 square inches. The 70-inch monitor measures 61.01" (155 cm) wide by 34.32" (87.2 cm) tall, covering 2093.8 square inches.
The practical difference: the 70-inch monitor is 29.3% wider, the 70-inch monitor is 158.7% taller, and 70-inch monitor offers 234.6% 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.
49-inch 32:9 vs 70-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 5120x1440, the 49-inch super ultrawide achieves 109 PPI. The 70-inch monitor at 3840x2160 reaches 63 PPI. The 49-inch super ultrawide has 42% 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 49-inch super ultrawide provides an effective diagonal of 27.1", while the 70-inch monitor provides 70". Check this if you watch 16:9 video or play games that do not support ultrawide resolutions.
