To calculate text width, use the Canvas.measureText() method in JavaScript. You can try to run the following code to get the text width −


<!DOCTYPE html>
         function displayTextWidth(text, font) {
            var myCanvas = displayTextWidth.canvas || (displayTextWidth.canvas = document.createElement("canvas"));
            var context = myCanvas.getContext("2d");
            context.font = font;
            var metrics = context.measureText(text);
            return metrics.width;
         document.write("Text Width: "+displayTextWidth("This is demo text!", "italic 18pt verdana")); //
