- Success Criterion 3.3.2
- Conformance level A
Numeric Field With No Stated Unit of Measurement
3.3.2 — Labels or Instructions
Scenario
Setting
A community forum's discussion thread
What’s wrong
Unit expectations unstated (kg vs lb, currency).
Example
A community forum's discussion thread shows the problem clearly: unit expectations unstated (kg vs lb, currency).
Why it matters
Everyone filling forms, especially people with cognitive disabilities and magnifier users. On a community forum's discussion thread, this barrier means they have to guess at the correct format.
How to test
Check for a stated unit (kg vs lb, currency) near any numeric input where units matter: if unstated, it fails.
How to fix
A persistent visible label must be provided, required status must be marked visually AND programmatically (with any symbol explained), and format rules stated before input.
Outcome
Corrected, a community forum's discussion thread now lets a visitor finish the task in one attempt.
Who is affected
Everyone filling forms, especially people with cognitive disabilities and magnifier users.
