MDN ARIA meter role
Documents meter as a read-only graphical display of a numeric value in a defined range, recommends native meter where possible, requires an accessible name, defines value attributes, and warns not to use meters for progress.
Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| AI confidence shown as fake precision | Flag this anti-pattern when an AI or automated surface shows a precise score without calibration scope, decision threshold, freshness, uncertainty reason, or safe next action. | The interface distinguishes raw internal scores from user-facing calibrated confidence. | Supports separating read-only bounded meters from AI confidence or probability displays. |
| Meter | Choose meter when a read-only scalar value has a meaningful minimum and maximum. | The meter is read-only; users cannot drag, type, increment, or submit the meter itself. | MDN supports read-only meter role semantics, accessible names, min/max/current values, useful value text, native meter preference, and progress distinction. |
