The 55-inch 16:9 TV measures 47.94" (121.8 cm) wide by 26.96" (68.5 cm) tall, with a total screen area of 1292.6 square inches. The 83-inch 16:9 TV measures 72.34" (183.7 cm) wide by 40.69" (103.4 cm) tall, covering 2943.7 square inches.

The practical difference: the 83-inch 16:9 TV is 50.9% wider, the 83-inch 16:9 TV is 50.9% taller, and 83-inch 16:9 TV offers 127.7% 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 distance, console use, video, and big-screen work, 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 55-inch 16:9 TV achieves 80 PPI. The 83-inch 16:9 TV at 3840x2160 reaches 53 PPI. The 55-inch 16:9 TV has 33.7% 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.
