Exploring techniques for creating realistic dimensions in CSS

My goal is to create a responsive website that accurately displays an object with specified dimensions, such as a width of 100mm, regardless of the user's screen resolution. However, I am facing challenges in achieving this consistency across all devices.

UPDATE: Here is the current code snippet that I have been working on:

var dpr = window.devicePixelRatio;
var inch = 25.4;

var pixelHeight = screen.height * dpr;
var pixelWidth = screen.width * dpr;

function calculatePpi(monitorDiagonal) {
    return (Math.sqrt(Math.pow(pixelWidth, 2) + Math.pow(pixelHeight, 2))) / monitorDiagonal;
}

function mmToPx(mm) {
    return  (((mm / inch) * calculatePpi(monitorDiag)));
}

Answer №1

To control the size of an element using CSS, you can adjust its height and width properties.

You can either set the height and width to automatically adjust (default setting where the browser calculates the dimensions), specify them in specific length units like pixels (px), centimeters (cm), etc., or as a percentage (%) of the containing block.

For instance, if you want to display an element with 35cm width and 50cm height, you would define it in CSS like this:

#example {
  height: 50cm;
  width: 35cm;
}

Best of luck!

Although this method should theoretically work, some users may find that it lacks precision. Take note of any comments for further guidance.
