The 70-inch 16:9 TV is 61.01" (155 cm) wide and 34.32" (87.2 cm) tall, while the 83-inch 16:9 TV is 72.34" (183.7 cm) wide and 40.69" (103.4 cm) tall. That makes the 83-inch 16:9 TV the larger screen by 40.6% of usable area.

The 70-inch 16:9 TV measures 61.01" (155 cm) wide by 34.32" (87.2 cm) tall, with a total screen area of 2093.8 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 18.6% wider, the 83-inch 16:9 TV is 18.6% taller, and 83-inch 16:9 TV offers 40.6% 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 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 70-inch 16:9 TV achieves 63 PPI. The 83-inch 16:9 TV at 3840x2160 reaches 53 PPI. The 70-inch 16:9 TV has 15.7% 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.
