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