UX Best Practices for Form Design
Minimize the Number of Fields
Less is more: Limit the number of fields to only what’s necessary. Each additional field increases cognitive load and can frustrate users.
Example: Instead of asking for full addresses on a contact form, request just an email and phone number.
Use Clear Labels and Instructions
Ensure every field has a descriptive label that tells users what information is required. If further explanation is needed, use placeholder text or tooltips.
Example: Instead of labeling a field "Name," specify "First Name" and "Last Name" separately if needed.
Input Validation and Error Handling
Provide real-time validation as users complete the form, and make sure error messages are clear and actionable. Users should know what went wrong and how to fix it.
Example: If a password doesn’t meet complexity requirements, specify exactly what is missing, like "Your password must include at least one number.
Use Inline Validation
Inline validation helps reduce frustration by helping users fix errors immediately. By choosing the appropriate field, automatic validation messages should appear. For example, if an email address is needed, the field form type chosen should be an email and not an open text field. Both options will allow for an email address provided, but only the email address field type will validate for proper input of the email.
Example: Show “Valid email” or “Invalid email format” as soon as the email field is filled out.
Logical Flow and Grouping
Group related information together and arrange fields in a logical order that mirrors the user’s mental model. This makes forms easier to follow.
Example: Group "Billing Address" and "Shipping Address" fields together when checking out on an e-commerce site.
Mobile Optimization
Our design system considers optimization of forms for mobile users by providing mobile-friendly tap targets and using mobile-specific keyboards (like numeric pads for phone numbers).
Progress Indicators for Multi-Step Forms
For longer forms (such as application processes), show users where they are in the process with a progress indicator to reduce anxiety and encourage them to complete it.
Example: An application form that shows “Step 2 of 3: Application” helps users feel they are making progress.
Accessible Design
Ensure forms are accessible to all users, including those with disabilities. Use proper ARIA labels, ensure contrast is high enough for readability, and make forms navigable via keyboard.
Example: Use descriptive alt text for any form icons and ensure form fields can be navigated without a mouse.
