TextMetrics: width property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

Note: This feature is available in Web Workers.

The read-only width property of the TextMetrics interface contains the text's advance width (the width of that inline box) in CSS pixels.


Start with this <canvas> element:

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

You can get a TextMetrics object using the following code:

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

let text = ctx.measureText("foo"); // TextMetrics object
text.width; // 16;
