Writing Accessible Meter Value Text
Writing Accessible Meter Value Text records the APG’s explicit user-friendly-value rule and keeps it separate from control labeling or progress-indicator guidance.
When a meter’s numeric value is not self-explanatory, provide user-friendly value text that adds the context needed to understand the reading.
Key details
Important caveats
Scope Boundary
This page covers wording of a meter’s user-friendly value text; minimum/maximum values, role choice, visual rendering, and update mechanics remain implementation concerns.
Further guidance
Content
Write value text that translates the raw measurement into user-meaningful information, adding context such as units or practical meaning when the number alone would be unclear.
Purpose
User-friendly value text helps assistive-technology users understand what the meter reading means instead of hearing an ambiguous number or percentage.
