CanvasRenderingContext2D: font property

Baseline 2025

Newly available

Since March 2025, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

See full compatibility

The CanvasRenderingContext2D.font property of the Canvas 2D API specifies the current text style to use when drawing text. This string uses the same syntax as the CSS font specifier.

Value

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

Examples

Using a custom font

In this example we use the font property to specify a custom font weight, size, and family.

HTML

html

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

JavaScript

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

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

Result

Loading fonts with the CSS Font Loading API

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

let f = new FontFace("test", "url(x)");

f.load().then(() => {
  // Ready to use the font in a canvas context
});
