100% crop = ??? full frame size ???

The last 2 charts suggest why it's impossible to make the chart....
still...
...since so many have posted their advice but did not answer my request, and as each monitor's specifications varies, I still would like to ask, if it would not be an inconvenience, a few people to post their 100% crop's full frame size, just to have an idea how they vary...
Again, thank you...

Nobody answered your question because there wasn't a question to begin with People told you the correct answer, which is: " It is not only meaningless to provide expensive lists of models and sizes, but also nearly impossible"

The 100% crop's full frame size is full frame. 160% crop is 1.6 crop. Again, the statements you are making simply do not make any sense. It's like taking a picture of a picture of a line with numbers. Not only does it make no sense except for the one that took them, but also makes no physical sense to anyone but the one that took them. If you want to embark on a journey of millions of camera- display combinations, feel free, but no-one else is on your wavelength and therefore can't even begin to understand what good that would do.

Let me recap the thread for you:
-All camera information you would need to know about printing resolutions is available at dpreview. This also includes pixel densities and format sizes.
-You cannot compare the size of a print at a certain dpi (display at some zoom level) without knowing the number of pixels in the image and the print (display) dimensions. Setting the equation to a certain pixel and physical dimension for a display, you can figure out how big a single pixel is and how many pixels from a 100% crop would fit.
- 100% crop is pointless because the viewable space on a 100% crop depends on how many pixels can be used in displaying it. That is to say that you can view something at 100% if it's 100x100 pixels or 1000x1000 pixels, and though the pixel density is the same, the space on the screen is different. Likewise, sharing this information with someone with a different screen is meaningless, as you would need to know the original size in inches (or mm, or whatever you like) and in pixels, as well as your current size. The end result is a lot of math for nothing learned.

By now, you have figured out that it will depend on the viewer's monitor how big the "full frame" size will be - it won't help you to know what size it would be on the poster's monitor, or would it?

I'm still not quite sure I understand what it is you are asking for

Do you need someone to do the math for you ( (# of pixels in width or height of camera sensor)/(ppi of monitor) = dimension of image) for each camera/monitor combination or am I missing something?

E.g., for a 100% crop from a 2000Hx3000W image (6 MP) viewed on a monitor with 100 ppi, the image full size would be 2000/100 so H = 20" while W = 3000/100 = 30"

Wow, it's like talking to a brick wall. It's not impossible at all. Time-consuming and tedious, yes. Impossible, no. All you have to do is this. Do. The. Math. Again, I've already posted a formula to use that uses physical monitor dimensions and resolution, and AJSJones has posted an alternative method that uses monitor PPI (which given the PPI/DPI table exists might be an easier formula to use). All you have to do is use a formula.

tdodd did it for 3 of his displays. You can do it for yours too. If you wanted to make a comprehensive table of all display sizes and resolutions vs. all cameras you could absolutely do it if you put forth the time.

+1.

I only posted my figures in order to be helpful, as I just couldn't be bothered to argue the toss about the futility of the exercise.

Never practiced rally with a brick wall before? Helps you improve your self a lot in tennis, especially in reducing wasted movements and varying your speed.

My monitor resolution is 100 ppi. That number will make it very easy for you to know the image size for any camera in the world on my screen. Simply stick a decimal point between the second and third digits of any pixel dimension.
