Question:
What's your favorite aspect ratio in general and/or for what specific
purpose?  4/3 has of course been the defacto standard for a long long time
but seems to be getting used less and less. Televisions are going one way
and computers are going with something else.  If you want to make an image
or video that might be displayed on different media or different devices,
what do you choose?  Here are a few common landscape ratios, but don't
forget their portrait equilvalents...


1/1           1:1 square
5/4        1.25:1 e.g. most 17" non-wide-screen monitors @1280x1024, 8x10
print
4/3       1.333:1 e.g. most displays
1/sqrt(2) 1.414:1 e.g. iso paper sizes, A4 etc
3/2         1.5:1 e.g. 4x6 print
16/10       1.6:1 e.g. wide-screen monitors
16/9      1.777:1 e.g. dvd's & widescreen tv
           1.85:1 e.g. not-so-wide cinematography (comedies)
           2.39:1 e.g. cinematography  (blockbusters)

Any others? Golden ratio (very close to widescreen monitors)?

My favorites are 4x3 for standard images, and 16x9 for ones that feel 
"artsy".

Visually, I like 16x9 landscape.  It feels comfortable to me, maybe because it suits
the human field
of vision well.  With that being said, I thing the resolution for an image should suit
the content,
even if it does not equate to one of the conventional aspect ratios.

It depends both on the subject and the purpose of the image.
I generally use 4x3 for screen display on my desktop or 16x10  on my laptop.
I can add square ratio 1x1 (120x120 mm) for CD sleeves or even 
2x1(240x120mm) for folded sleeves

well i purpose the golden ratio

1 / phi = 1 / (( 1 + sqrt(5)) / 2 )   = 1 / 1.618

example:  640 x 395 - 800 x 494 - 1024 x 632 - 1280 x 791

It highly depends on the type of scene, but I favour 1/1, 4/3, and 16/9 
(both in landscape and portrait mode). In a few cases, I tend towards 
extremely flat (or narrow) ratios. I never consider their usage for screen 
monitors or any standardization. The ratio is always a purely subjective 
choice. Until now, I didn't consider the golden ratio, but I might.

4/3 for most renders, 1/1 for textures and fractals. Although, I think I 
will now experiment with other ratios (8/3, 12/3) for landscapes. A 
little bit of light-bleed coming up from the image into the black space 
would look really good, I think.

Yes I have a set of sizes based on ratio of 1.618:1 in my resolution ini 
file

I also have a set of sizes based on strait 2:1

Then there are 1:1 and 4:3 of course.

My Favorite is 4/3 (Specifically 8 by 6 inches).  This is mostly because
this is by far the most common "large"-print and frame size (in New Zealand
anyway) and is also the higher-quality aspect-ration of my digital camera. I
started with photography before I got into raytracing.
I like A4 size but rarely use it now as getting good frames can be a
nuisance.
I'm starting to use wide screen (1680/1050 pixels) now that the screens are
becoming more common.

42 of course... to whatever works.

And I don't worry about the porpoise, it can take care of itself.
