You should check the color filters: Settings -> Accessibility -> Display Accommodations -> Color Filters. Disable the Color Filters if they are enabled.

One can take a screenshot using their device then view the size of that screenshot image.

If you had a page that displayed a bunch of Millimeters and different sets of one to 100. They couldn’t be totally random they would have to line up on your screen correctly with an actual one tab 100 mm stick ruler. And you have to have a table corresponds with which one lines up correctly on your screen with the one you have in your hand. So I guess you’d have to have a ruler or some sort of measuring device or credit card if all the marks were in credit card sizes. I’m not gonna do all the math but somebody. I believe could be wrong

Try this on for size:
https://www.infobyip.com/detectscreenresolution.php
It will use JavaScript in the web page to show you your screen resolution. I dug into it using the console, and here is the relevant code:
var devicePixelRatio = window.devicePixelRatio || 1;
document.getElementById(‘width’).innerHTML = screen.width * devicePixelRatio;
document.getElementById(‘height’).innerHTML = screen.height * devicePixelRatio;
document.getElementById(‘depth’).innerHTML = screen.colorDepth;
var div = gcd(screen.width, screen.height);
var wd = screen.width / div;
var hd = screen.height / div;
document.getElementById(‘aspect_ratio’).innerHTML = wd + ‘ / ‘ + hd + ‘ = ‘ + Math.round(100 * screen.width / screen.height) / 100;
So, you could put this in a local HTML file and do it yourself!
