1:1 crops the image square
3:2 is native (35mm film, APS-C, and "full frame") aspect ratio
4:3 is old NTSC TV (pre-digital) aspect ratio and is native to Micro 4/3 and most smartphone cameras.
16:9 is new HDTV/4K aspect ratio and is native to all new video cameras.
Always express the horizontal dimension FIRST. Horizontal is usually the side of the camera with the tripod socket facing down. Every graphic designer worth her salt will appreciate that bit of clarity. So will many photo labs and printers.
7:5 and 5:4 are not native to any sensor format I'm aware of... This drives ordinary citizens crazy.
If the aspect ratio you choose is not native to the camera, you crop (discard) pixels to achieve that crop. Sometimes that's desirable; sometimes cropping in post-production is preferable.

All good info from Burkphoto. I prefer to crop in post in most instances. For certain publications a specific aspect ratio may be required in that case the cropping in camera may be preferable.

Yes - but I do prefer 4:3, and so my usual goal is to fill the frame - hence no loss of pixels.
I like to get it all. Unfortunately I sometimes don’t get enough around the edges to convert my 3:2 images to 16:9 wallpapers.

Then why are the results different?
3 vs. 4
How about 1.333? (or .75)
I have a Bronica ETRSi 6x4.5 camera, and a Lumix GH4 Micro 4/3 camera (4:3 natively). Copying old negatives from the 6x4.5 camera, I crop nothing and waste no sensor area. They are e the same shape (aspect ratio).

That is true.
I was confused about the equations that yielded a value of 3 and 4. I thought you were referring to ratios.

Always seemed odd to me that to get a 4x6 print, you need a 6:4 (or 3:2) aspect ratio!
Yep. Aspect ratios are formal. When we lab rats refer to 4x6, we mean a vertical print. 6x4 is horizontal. The difference matters for some digital products and some frames.

Haha. (I'm not a lab rat.)
When I refer to 4x6 , 5x7, 8x10, ... I'm just referring to the size, only.
I don't care about orientation. Obviously it depends on the image.
"Do you want a 5x7 of that or 8x12?". If there is an image in mind, I think people are smart enough to figure it will be tall (↨) or long (↔).
I always put the smaller number first, always.
Frames are sold as 5x7s, 8x10s, etc.
But I suppose there will be some people looking for a 10x8 frame for a landscape image.
Even when I worked at a camera shop, the processing envelopes only had 4x6, 5x7, 8x10, ... check boxes for the
size of the prints. The lab didn't care about orientation, unless it was masked, then we included masking instructions.

We had many special products for schools. For example, standard groups were horizontal, but cheerleaders frequently wanted verticals of their pyramids and horizontal portraits of themselves posing on the gym floor. The images went into digitally framed designs. So we had to know…

That is a specialized application. Not getting run of the mill prints from a file.
I was working with prints WAY, way before digital frames! Those XxY sizes usually refer to prints, not digital frames. Digital frames will compensate for the size, but not the orientation.
And I was referring to frames for paper prints, which is most common. Requests for digital frames are less frequent, and it does depend on the orientation of the image.
Standard groups and cheer leading type image formats (landscape/portrait) are done when the pictures are taken, not printed, which kinda precludes the print orientation.

Digital memory mates is the product… we sold millions of them.
In the 1970s, ‘80s, and ‘90s, we sold a single product that included a folder and two prints. It could be ordered with horizontal group, vertical group, horizontal portrait or vertical portrait, in any combination of sizes from 3.5x5 to 8x10. (Or vice-versa…)

Yea, and I'll bet the shots were
taken with the desired aspect ratio in mind (portrait v. landscape).
See, even you referenced "8x10" as a size... as opposed to 10x8 for orientation.

The actual products were described properly on our electronic order system as, for example, “10x8 group with 5x7 individual,” or “8x10 group with 5x7 individual,” or “10x8 group with 7x5 individual.” Nothing was left to chance. Everything had a separate catalog number.

Confused - you printed an 8x10 group shot as a 10x8 if they wanted?

No. We printed a 4:5 aspect ratio image inside of a digitally printed graphic design on at least an 8x10 inch size sheet of paper. The paper was big enough to incorporate both the group and individual images. The graphic design was a full edge to edge bleed. It included school mascot, name, year, team name, group names, and individual name, if they paid for all those options.

Got off the subject of printing a single image did we?
