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.
Purpose
Clear timing instructions help users plan a task and understand how a time-limited interaction behaves.
