HTMLCanvasElement: height property

The HTMLCanvasElement.height property is a positive integer reflecting the height HTML attribute of the <canvas> element interpreted in CSS pixels. When the attribute is not specified, or if it is set to an invalid value, like a negative, the default value of 150 is used.

This is one of the two properties, the other being HTMLCanvasElement.width, that controls the size of the canvas.


A number.


Given this <canvas> element:

<canvas id="canvas" width="300" height="300"></canvas>

You can get the height of the canvas with the following code:

const canvas = document.getElementById("canvas");
console.log(canvas.height); // 300
