More than 25% of the population may have difficulty completing a form if it's not accessible. With Diamond, you can create accessible forms that comply with WCAG standards (Web Content Accessibility Guidelines).

WCAG & Accessible Forms

A form is often the most important interaction on your website: requests, orders, registrations, complaints, or contact. If your form doesn't comply with WCAG 2.1 or WCAG 2.2 guidelines, you'll not only lose visitors, but also revenue and customer satisfaction.

Benefits of accessible forms for your organization:

  • Greater reach: Your website forms are also accessible to people with disabilities.
  • Compliance with international accessibility standards (WCAG).
  • Better user experience and higher conversion rates.
  • Compliance with legal obligations such as the Digital Accessibility Act.
  • Improved SEO through structured, semantic, and accessible HTML.

The 4 WCAG Principles for Accessible Forms

The WCAG guidelines are based on the POUR model:

  1. Perceivable: Information must be perceptible to everyone. Clear labels, alt text, and sufficient color contrast are essential.

  2. Operable: Your form must be operable using various methods, not just a mouse, but also keyboard navigation or voice control.

  3. Understandable: Clear instructions, a logical sequence, and clear error messages help users complete the form correctly.

  4. Robust: The form works reliably on all devices, browsers, and assistive technologies.

Checklist: Make your forms WCAG-compliant

Use this checklist as a guide when designing digitally accessible forms conform WCAG:

  • Clear labels for each field: Ensure the label specifies exactly what data is being requested. Add title and aria attributes where necessary.
    Note: Placeholder text alone in a field is not sufficient.

  • Adequate color contrast: Ensure sufficient contrast between text and background for optimal readability.
    Tip: Use an accessibility contrast checker such as WebAIM.

  • Fully keyboard-accessible: Check whether the form can be navigated logically using the Tab key, without skipping fields or instructions.

  • Clear and specific error messages: In the error message for incorrectly filled fields, explain what is wrong and how the problem can be resolved.
  • Autocomplete frequently requested fields: Speed up form completion by automatically completing frequently used data with the autocomplete attribute.

  • Multiple input methods: Offer alternatives, such as entering dates manually or using a calendar selection.

  • Screen reader testing: Check the accessibility of your forms with a screen reader, such as NVDA(Windows) and VoiceOver (Mac).
  • Mobile-friendly design: Ensure that fields and buttons function properly and are readable on different screen sizes.

  • Extend or disable time limits: Offer the option to add extra time or disable time limits, for example, for users of assistive technology.
