SVGUseElement: 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.

The width read-only property of the SVGUseElement interface describes the width of the referenced element as an SVGAnimatedLength. It reflects the computed value of the width attribute on the <use> element.

The attribute value is a <length>, <percentage>, or <number>. The numeric value of the SVGAnimatedLength.baseVal is the width of the referenced element in the user coordinate system.

Value

An SVGAnimatedLength.

Examples

Given the following SVG:

html
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
  <defs>
    <circle id="circle1" cx="50" cy="50" r="40" fill="blue" />
    <circle id="circle2" cx="50" cy="50" r="40" fill="red" />
  </defs>
  <use x="50%" y="50%" href="#circle1" width="50" />
  <use x="25%" y="50%" href="#circle2" width="100" />
</svg>

We can access the computed values of the width attributes:

js
const uses = document.querySelectorAll("use");
const widthUse1 = uses[0].width;
const widthUse2 = uses[1].width;

console.log(widthUse1.baseVal.value); // output: 50
console.log(widthUse2.baseVal.value); // output: 100
