HTML | DOM image naturalWidth property

It is a read-only property.

Return Value: It returns the original width of the image in pixels.



    <img src=
id="image" alt="" width="250" height="205"
class="alignnone size-medium wp-image-1092360" />
    <button type="button" onclick="getWidth()">Click</button>
    <div id="text"></div>
        function getWidth() {
            var imgObject = document.getElementById("image");
            var output = document.getElementById("text");
            output.innerHTML = "Width of image: " + imgObject.width +
            "<br>naturalWidth of image: " + imgObject.naturalWidth;
