WCAG 3.3.2: Labels or Instructions
Published by whatisADA / Grow Wild Agency · Updated
What this criterion means
Provide labels or instructions when users must enter information. Explain the requested value and necessary conditions at the point where the person needs them.
A practical example
A document uploader accepts only PDF files below a size limit. Name the input “Upload your application PDF” and show the allowed format and size before submission, rather than revealing every condition only after failure.
How to check it
- Review each field, selection group and upload control for a visible label or useful instruction.
- Check that required formats, limits and unusual constraints are explained before input.
- Complete the form without relying on placeholder text that disappears as soon as typing begins.
What can be missed
More instruction is not always better. Keep essential guidance close and concise, then provide optional details without making every field label excessively long.
Record your test

These are your observations, not automated results or a conformance certificate. A complete evaluation needs appropriate scope, supported technologies, all applicable criteria and relevant page states.
Primary sources and scope
This is independent implementation guidance with original examples. The linked standard contains the full definitions, exceptions and conformance requirements. A criterion or checklist alone does not establish legal applicability or whole-site conformance.
