WCAG Guideline 2.2.1: Timing Adjustable Explained
Estimated read time: 7–8 minutes
Guideline 2: Operable
The Operable principle ensures that all users can interact with and control web content, regardless of their abilities. This includes giving users enough time to read and use content, especially when time limits are involved.
Guideline 2.2: Enough Time
Guideline 2.2 focuses on making sure users have enough time to complete tasks. Time limits can create barriers for people with disabilities, so flexibility is essential.
What Is Guideline 2.2.1 Timing Adjustable?
"For each time limit that is set by the content, at least one of the following is true: the user can turn off, adjust, or extend the time limit."
Guideline 2.2.1 Timing Adjustable is a requirement in the Web Content Accessibility Guidelines (WCAG) .
- Users must be able to turn off, adjust, or extend any time limits set by the website or app.
- Exceptions: time limits that are essential, required for real-time events, or longer than 20 hours.
- Applies to forms, quizzes, logins, and any interactive content with a timer.
This means users who need more time—due to disability, distraction, or any other reason—aren’t unfairly penalized by time limits.

Why Does It Matter?
- Inclusivity: Time limits can exclude users who need more time due to disabilities.
- Legal Compliance: Timing Adjustable is a Level A requirement in WCAG 2.1 and 2.2.
- Usability: Prevents frustration and loss of work for all users.
