Do not disable or suppress the ability to zoom

Why is this important?

With more and more devices supporting pinch zooming, it is becoming more relevant to allow users to zoom into parts of a website. Certain websites disable the ability to zoom in order to keep their desired visual appearance. We need to consider that users with certain visual requirements need the ability to zoom into a page. This is usually because these users may not able to digest content as in their default state on a website. Users with small devices such as mobile phones also find the ability to zoom very useful.

How can I resolve this issue?

Do not disable the ability to zoom.

What topics do this checkpoint affect?

  • Accessibility (WCAG 2 Level AA, 1.4.4,  WCAG 2.1 Level AA, 1.4.10)
  • Usability

Can you explain how this checkpoint works?

The checkpoint examines the entire HTML source code of a page and reports if within the meta tag, the attribute user-scalable is set to 0 or no as well as if maximum scale is 0 or 1.

User-scalable allows the device to zoom in and out, having a value of 0 or no asks the device not to zoom
maximum-scale indicates the maximum amount the visitor can zoom on the page. Setting a value of 1.0 indicates that the page does not zoom.
