how much bigger is 42" tv vs a 37" tv (? %)

[kreactor]

and please show how the answer is calculated

thanks

(trying to figure out if ~1k more is still a good deal for a 5" larger set)

well, the " measures are diagonal, use some trig and figure it out

 

[Whoozyerdaddy]

For the 42" Measure the screen.. LxH=X
For the 37" Measure the screen.. LxH=Y

X-Y=Z

Z/X=% Difference in overall picture area (How much bigger the 42" is than the 37")

42 / 37 = 1.135135...

13.5%

That doesn't account for the total difference in viewing area. Only the difference from one corner to the other.

~13.5% larger?:

42/37 = 1.135

(37/100)*13.5 = 4.995 -> 37 + 4.995 = 41.995 ~= 42

I believe the assumption here is the loss in viewing area is equal in the two screens and isn't taken into account.

Until I get my site back up & running, use the original (that I improved upon):

http://www.cavecreations.com/tv2.cgi

A 42" 16:9 set has nearly 30% more viewable area than a 37" 16:9.

ViperGTS, you beat me to it, that cavecreations hdtv size calc is a permanent member of my favorites.

 

[mercanucaribe]

No, just sit closer.

Once I get my host to update a few libraries mine will be back online - www.tvcalculator.com.

It has a few additions that the cavecreations site is lacking (namely support for 16:10 and 5:4 displays).

From time to time, I have looked for this dumb thing. Takes me 30 minutes to find it every time I look for it. This will definitely be added to my bookmarks this time. Last time I looked for it, I could not find it after an hour so I got a guy a work to tell me how you'd calculate this with pen and paper.

a^2 + b^2 = c^2

thanks for the info, cool calculator
