Is there a way to change the DPI of Paint itself to the monitor's PPI?

[JacobU]

I was trying to make the "inches" of paint.net as accurate to my monitor as I could (just because I wanted to). My monitor has a PPI of 100.45, which I was able to calculate using this website: https://www.calculatorsoup.com/calculators/technology/ppi-calculator.php and was able to verify with this website: https://www.ginifab.com/feeds/cm_to_inch/actual_size_ruler.html?

After adjusting the ruler displayed in the second website accurate to my monitor, I took a screenshot, and pasted it to Paint.net. (And changed the setting under View to display Inches instead of Pixels). Shifted over the 0 to match up with left side.

And it wasn't the same.

It's kinda hard to see, but the top is displaying inches.

I dug into the settings of Paint, and found that under Diagnostics, it said the Monitor has a DPI of 96.

As I understand, DPI and PPI are not the same, but they are related when it comes to image resolution.

Using the second website again, this time setting it to 96 PPI, screenshoting that, pasting it, etc...

Now they match up perfectly.

But I would like it if Paint's DPI matched up with my monitor's PPI. So is there a way to change Paint's DPI to 100.45? Or am I SoL?

 

(Oh, and this is my first time posting here, so I apologize if this isn't the correct forum to post this. This was the first thing to bug me enough to post here, and google has become useless at actually finding what you want.)

This is what you might call the "old fashioned" way of reporting this information. Nowadays Windows just calls it "scaling factor". 96 "DPI" is 100% scaling, 192 "DPI" is 200% scaling, and so on. In other words, don't take that "DPI" value literally. It's not a real, physical DPI value.

 

The DPI for the image you're working on is configurable via Image->Resize. Just set it to whatever you want it to be. You don't configure Paint.NET's DPI -- it doesn't have one, at least not as far as the ruler is concerned. You set the image's metadata with the DPI value you want to work with.
