70 Inch Vs 55 Inch Tv. As a 4 3 display. In my side by side tests the 2020 lg cx is the best tv i ve ever reviewed barely beating the 2019 b9 which like other 2019 oled tvs is mostly sold out these days.
29 smaller diagonally and 49 smaller by area as a 16x9 display. As a 4 3 display. So given our nine foot example that means a tv around 68 inches so a 65 or 70 inch model would work.
7 14 larger diagonal 14 80 larger area.
27 27 larger diagonal 61 98 larger area. 55 65 77 inch. How much bigger is one screen vs. 29 smaller diagonally and 49 smaller by area as a 4x3 display.
