Crafting Accessible Icons for All: A Step-by-Step Guide
Creating Symbols for Your Designs that are Easy to Understand for Everyone
In the realm of digital design, creating accessible icons is of paramount importance to ensure compliance with the Web Content Accessibility Guidelines (WCAG). Here's a comprehensive guide to help you craft WCAG-compliant icons:
1. Embracing Accessible Design Principles
- Clear and Simple Icons: Use straightforward, recognisable shapes to clearly communicate the icon's purpose. Avoid intricate designs that may confuse users [4].
- Visibility and Contrast: Ensure icons are large enough and have sufficient contrast with the background. This is essential for users with visual impairments [1][4].
- Semantic Meaning: If icons convey information or represent actions (e.g., search or email icons), they should be unambiguous and easily comprehensible [4].
2. Adhering to WCAG Requirements
- Alt Text: Add descriptive alt text to icons that provide information or actions. This aids screen readers in describing the icon to users [4].
- ARIA Labels: Use on interactive elements to provide a clear description of what the icon does. This is crucial when icons are the only visual cue [3].
- ARIA Hidden: If an icon is purely decorative and provides no meaningful information, use to prevent unnecessary screen reader announcements [3].
3. Utilising Design Tools for Accessibility
- Platform's Accessibility Design Tool: Use our platform's Accessibility Design Tool to prioritise accessibility one icon at a time. It offers a simple drag-and-drop interface to mark icons as alt text or decorative [3].
- Accessible Templates: The platform provides accessible templates with accessible icons, some of which are free and some require a small monthly fee [5].
4. Leveraging Scalable Vector Graphics (SVGs)
- Keyboard Accessibility: Make interactive SVGs focusable and operable via keyboard [5].
- Accessible Colors: Use texture, labels, or patterns to reinforce meaning, especially for colorblind users [5].
5. Testing with Assistive Technologies
- Screen Readers: Test your icons with screen readers like VoiceOver, NVDA, or TalkBack to ensure they are read correctly and behave as expected [5].
By adhering to these guidelines, you can create icons that are visually appealing and accessible for diverse audiences, while ensuring compliance with WCAG standards.
Additional Considerations
- Inclusive Icons: Avoid using icons that could be considered discriminatory or exclusionary in accessible design.
- Icon Sizes: Ensure icons are large enough (at least 44 x 44 pixels) to maintain readability [2].
- Color Contrast: Maintain a color contrast ratio of 4.5:1 for accessibility [2].
- Decorative Icons: Decorative icons do not require alt text [6].
- Scalable Vector Graphics (SVGs): SVGs with proper accessibility features are an accessible alternative to icon fonts [7].
Remember, accessible icons are a cornerstone of accessible design and ensure that the visual information in a design can be understood by everyone, including people with vision impairments, colour blindness, and those using assistive technology [8].
