Using the aria-valuemax attribute


The aria-valuemax attribute is used to define the maximum value allowed for a range widget such as a slider, spinbutton or progressbar.

If the aria-valuenow has a known maximum and minimum, the author SHOULD provide properties for aria-valuemax and aria-valuemin. The value of aria-valuemax MUST be greater than or equal to the value of aria-valuemin.

aria-valuemax is a required attribute of role slider, scrollbar and spinbutton.

Possible effects on user agents and assistive technology 

If the aria-valuemax is indeterminate, or if aria-valuemin is not less than or equal to the value of aria-valuemax, this creates an error condition that will be handled by the assistive technology.

Note: Opinions may differ on how assistive technology should handle this technique. The information provided above is one of those opinions and therefore not normative.


Example 1: 

The snippet below shows a simple slider with a maximum value of 10.

<div role="slider" aria-valuenow="4" aria-valuemin="1" aria-valuemax="10">
