total viewing area of 1 tv over another

I was wondering how much larger a 42 inch tv as opposed to a 37 inch tv in terms of viewing area.

I saw something that said a 47 inch was 62 percent larger than a 37 in terms of viewing area. Is there a chart that says how much larger one tv is over another in terms of viewing area?


I tried looking up the specs on various tv s but they only give the exterior dimensions, not the interior.

Thanks and happy new year.

just do the math.

16:9 format

37 inches dia

find sq inches

do it again for another TV

divide

Ok.. New Year. I am here to help.

Here are my three plasmas with quick rounded measurements...

37" is 32x18 = 576
42" is 36x20 = 720
63" is 55x32 = 1760


42" is 125% the size of a 37"

63" is 300% the size of a 37"

63" is 244% the size of a 42"



Your basic question answer = 42" is 25% larger than a 37" in viewing area.

Found a calulator online...

Thanks!

You da man !

I found another way to do it as well....

If the aspect ratio is the same (16:9 for all HDTVs), just square the ratio between the diagonals, i.e. (42/37)² = 1.29 = 129% = 29% larger area

It does not have to be exact, just a rough measurement.

OK, based on the above formula, this is what I came up with.

If the aspect ratio is the same (16:9 for all HDTVs), just square the ratio between the diagonals, i.e. (42/37)² = 1.29 = 129% = 29% larger area

42 vs 37 ... 29 percent larger

46 vs 37 ... 55 percent larger

52 vs 37 ... 98 percent larger

46 vs 42 ... 20 percent larger

52 vs 46 ... 28 percent larger

When you are comparing sizes, it is easier for me to see it this way and know the actual increase in area. It is easier for me to see that a tv is 55 percent larger than saying it is 9 inches wider.

Just thought you would like to know.
I know you have wanted to know this for yourselves.
Now your lives can return to normal.

very smart!

I have been in the HT biz for 15 years, never knew that.
