CanvasRenderingContext2D: font property
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
js
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.
js
let f = new FontFace("test", "url(x)");
f.load().then(() => {
// Ready to use the font in a canvas context
});
