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 markerHeight attribute represents the height of the viewport into which the <marker> is to be fitted when it is rendered according to the viewBox and preserveAspectRatio attributes.

You can use this attribute with the following SVG elements:

<marker>

Usage notes

Value	`<length-percentage>` \| `<number>`

<length-percentage>: This value defines either an absolute or a relative height of the marker. Relative values refer to the height specified via the viewBox and preserveAspectRatio attributes.
<number>: This value defines the height of the marker in the units defined by the markerUnits attribute.

A value of zero disables rendering of the element and negative values are an error.
