Visualizaçõesget image size inside <img> tag with object-fit
How can I get the size of an image that is already rendered on the browser, inside <img /> tag with object-fit: contain property?
As you can see, img tag fit 100% of container, but image inside doesn't. I need size of the image, not the tag
naturalWidth clientWidth and width does not return the desired value

You can use offsetWidth to get the width of any element
function func() {
var imgTag = document.getElementById("imgTag")
var demo = document.getElementById("demo")
demo.innerHTML = imgTag.offsetWidth
}<img src="https://pixy.org/src/477/4774988.jpg" width="200" height="200" id="imgTag" />
<button onclick="func()">Get width</button>
<div id="demo"></div>

You can use window.getComputedStyle()
let para = document.querySelector('p');
let imgWithNoStyle = document.getElementById('noStyle');
let imgWithStyle = document.getElementById('withStyle');
let imgWithNoStyles = window.getComputedStyle(imgWithNoStyle);
let imgWithStyles = window.getComputedStyle(imgWithStyle);
para.textContent = `
My computed img with no style is:
${imgWithNoStyles.objectFit}
${imgWithNoStyles.width}
${imgWithNoStyles.height}
and my computed img with style is:
${imgWithStyles.objectFit}
${imgWithStyles.width}
${imgWithStyles.height}
`;.with-style {
width: 200px;
height: 300px;
border: 5px solid black;
object-fit: fill;
}<p>Hello</p>
