The CanvasRenderingContext2D.font property of the Canvas 2D API specifies the current text style being used when drawing text. This string uses the same syntax as the CSS font specifier. The default font is 10px sans-serif.


ctx.font = value;


A DOMString parsed as CSS font value. The default font is 10px sans-serif.


Using the font property

This is just a simple code snippet using the font property to set a different font size and font family.


<canvas id="canvas"></canvas>


var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");

ctx.font = "48px serif";
ctx.strokeText("Hello world", 50, 100);

Edit the code below and see your changes update live in the canvas:

Loading fonts with the CSS Font Loading API

With the help of the FontFace API, you can explicitly load fonts before using it in canvas.

var f = new FontFace("test", "url(x)");
  f.load().then(function() {
    // Ready to use the font in a canvas context
