To draw large font properly in HTML5 Canvas, you can try to run the following code −
var myCanvas = document.getElementById("myCanvas"); var context = myCanvas.getContext("2d"); context.font = '180pt Georgia'; context.strokeStyle = "#FF0000"; context.fillStyle = "#FFFFFF "; context.lineWidth = 34; context.fillText("Demo!",0,200); context.strokeText("Demo!",0,200);
