Expectations
Screen Reader support by expectation
| Expectation | JAWS | Narrator | NVDA | Orca | TalkBack | VoiceOver (iOS) | VoiceOver (macOS) | ||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| Chrome | Edge | Firefox | Edge | Chrome | Edge | Firefox | Firefox | Chrome | Safari | Safari | |
| MUST convey when the maximum length is reached | none | none | none | none | none | none | none | none | supported | none | supported |
| MAY convey the maximum length when navigating to an input | none | none | none | none | none | none | none | none | none | none | none |
Expectation: convey when the maximum length is reached
Rationale:
The attribute prevents characters beyond the maximum length from being entered. The user needs to know when the maximum length has been reached, so that they do not think that they are entering data when they are in fact not.
Strength of this expectation for different types of assistive technologies:
- Screen Readers: MUST
- Voice Control: NA
Examples:
- screen readers might announce an earcon when the user tries to enter data beyond the maximum length.
- screen readers might imply that the maximum length has been reached by not announcing anything when a user tries to enter data (usually the keypress is echoed)

Expectation: convey the maximum length when navigating to an input
Rationale:
The user may wish to know the maximum length when navigating to an input, and before they enter any data.
Strength of this expectation for different types of assistive technologies:
- Screen Readers: MAY
- Voice Control: NA
Examples:
- screen readers might announce the maximum length when navigating to an input.
