Forms & Inputs · validation, forms
Updated 2026-07-28
- Validation timing changes how feedback feels.
- Avoid validating too early:
- The user is still thinking.
- Errors feel like interruptions.
- Avoid validating too late:
- Users complete unnecessary work.
- Multiple errors appear at once.
- Use the right moment:
While typing
- For helpful guidance.
- Password strength.
- Formatting hints.
On blur
- For completed fields.
- Email checks.
- Required values.
On submit
- Good validation feels like assistance, not punishment.
