HTMLMeterElement: max property

Baseline Widely available

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

The max property of the HTMLMeterElement interface represents the maximum value of the <meter> element as a floating-point number. It reflects the element's max attribute, or the min value if no max is set, or 1 if neither the min or the max is defined.

This property can also be set directly, for example to set a default value based on some condition.

Value

A number.
