MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

WebGLRenderingContext.drawingBufferHeight

The read-only WebGLRenderingContext.drawingBufferHeight property represents the actual height of the current drawing buffer. It should match the height attribute of the <canvas> element associated with this context, but might differ if the implementation is not able to provide the requested height.

Syntax

gl.drawingBufferHeight;

Examples

Given this <canvas> element:

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

You can get the height of the drawing buffer with the following lines:

var canvas = document.getElementById('canvas');
var gl = canvas.getContext('webgl');
gl.drawingBufferHeight; // 150
