5 Must-Know Accessibility Rules for Inclusive Design
As a designer, your role goes beyond creating visually appealing interfaces. You need to ensure that every product is inclusive, accessible, and usable by a diverse range of people. Accessibility in design is an essential part of building digital products that everyone can use and enjoy. To help with this, here are some essential design considerations every designer should keep in mind.
Colour Contrast Check
- When designing for accessibility, colour choices are one of the most important considerations.
- Text and interactive elements should have enough contrast to remain readable against their backgrounds.
- Ensure that text and interactive elements meet WCAG AA contrast ratios of 4.5:1 for body text and 3:1 for large text.
- Do not rely on colour alone to convey meaning (e.g., error state should also have an icon or text, not just red).
- Every meaningful visual asset should either have a label in the interface or be paired with alternative text so its purpose is clear.
- Decorative images, by contrast, should be identified as non-essential, ensuring they don’t create unnecessary noise for screen reader users.
- Input fields and interactive components need explicit, visible labels so users always know what is being asked of them.
- Error messages should also be easy to understand, guiding users toward how to resolve issues instead of simply pointing out what went wrong.
- For mobile and touch devices, interactive targets such as buttons or form fields must be at least 44 by 44 pixels to remain comfortably usable.
- Keyboard Navigation Keyboard accessibility should be considered at the design stage as well.
- Every interactive element, whether it’s a button, menu, or form field, should be easy to navigate using only the keyboard.
- Clear and consistent focus states are essential so users can see exactly where they are as they move through the interface.
- Fonts should be large enough to read comfortably and designed to scale without breaking the layout.
- Consider scalable fonts that work well when zoomed to 200%.
- Avoid all-caps for long blocks of text.
- Line lengths should remain within a comfortable reading range, ensuring that text feels easy to read and understand.
- Providing adequate spacing between elements reduces cognitive load and helps users process content more easily.
