Writing Accessible Time-Limit Instructions
Writing Accessible Time-Limit Instructions narrows the preliminary timing topic to directly supported user-facing wording about time limits and available controls.
Write time-limit instructions early enough for users to understand the constraint, and explain available adjustment or extension options rather than relying on a surprise countdown.
Key details
Important caveats
Scope Boundary
This page covers user-facing time-limit wording; implementation of timers, exceptions, and extension mechanics remains a separate accessibility concern.
Further guidance
Content
State meaningful time limits before they become a surprise and explain available controls or extension options when they exist.
Practical Application
Tell users about meaningful time limits before they encounter them and explain any available extension, adjustment, or pause option in the same task context.
Purpose
Clear timing instructions help users plan a task and understand how a time-limited interaction behaves.
Reader Check
Could a user plan the task before the timer becomes urgent, including knowing what extension options exist?
Worked Example
Example: Before a timed form begins, write “You have 20 minutes. You can request more time from the timer menu before the session expires.” when that option is available.
