For those who want to compare the area size difference for any two TV sizes, here is how one can calculate it:
- Problem: Screen sizes are always given diagonally without the screen dimensions and it also makes the comparison of actual viewing area difficult
- Solution: Just replace the diagonal screen size number in the formula below
- Actual TV sizes will be a bit different, say 54.5 inch, but let's take full 55 and 65 inches for an estimated size
- I have taken Sony OLED TV 2018 A8F 55 inch (est Rs.1.60-2.20 lacs) and 65 inch (est Rs.2.90-3.50 lacs) prices here as an example (actual prices may change)
- You can use this formula to compare the price difference OR to see how much bigger a new TV will be compared to your present TV
- This is based on the Pythagoras equation: a^2 + b^2 = c^2
55 inch TV at 16:9:
- 47.94 inch x 26.96 inch Display Size
- 1,346 sq.inch Total Area
- Formula: (55x55) / 1.3164 = 2298 (under root) = 47.94 x 9/16 = 26.96
65 inch TV at 16:9:
- 56.65 inch x 31.87 inch Display Size
- 1,805 sq.inch Total Area
- Formula: (65x65) / 1.3164 = 3210 (under root) = 56.65 x 9/16 = 31.87
Total Area Difference: 34%
- Formula: [(1,805 - 1,346) / 1,346] x 100
Conclusion:
- Price Difference: In this example, Sony is asking for 60% to 80% more in price for a 34% increase in screen area when you go for a 10 inch higher screen from 55 inch to 65 inch for their OLED TV. For any TV, I always recommend going for the biggest screen size that you can afford. But such a high difference does not make it very cost effective for those who are on a budget, specially when OLED and QLED tech is still too costly.
- Size Difference: If you already have a 55 inch TV, then you will only be getting a 34% increase in total viewing size when you go for a 65 inch TV. A jump from 42 inch to 55 inch will give an approximate 72% more viewing area which is a better upgrade.
