What is Accessibility in Design?
Accessibility in design is the practice of building digital products that everyone can use, including people with visual, motor, auditory or cognitive disabilities. It removes barriers to interaction, widens the audience a product can reach, and improves the overall experience for all users.
How does accessibility in design work?
Accessibility in design works by anticipating the full range of ways people perceive, navigate and interact with a product, then removing the barriers that would exclude some of them. A person might use a screen reader, rely on keyboard navigation, need larger text, depend on captions or struggle with low-contrast colour. Accessible design accommodates these needs through deliberate choices in layout, colour, typography, interaction and content structure.
Most of this work is guided by the Web Content Accessibility Guidelines (WCAG), an internationally recognised standard organised around four principles: content must be perceivable, operable, understandable and robust. Meeting the AA level of WCAG is the common target for most products and is frequently referenced in legal and procurement requirements.
What are examples of accessible design?
Accessibility shows up in many small, concrete decisions:
- Sufficient colour contrast between text and background so it is legible for low-vision users.
- Text alternatives for images so screen readers can describe them.
- Keyboard navigation for every interactive element, not just mouse or touch.
- Clear labels and focus states so people always know where they are.
- Captions and transcripts for audio and video content.
Why accessibility in design matters
Around one in five people lives with some form of disability, so accessible design directly expands the audience a product can serve. It also improves the experience for everyone: captions help users in noisy environments, high contrast helps in bright sunlight, and clear structure helps people under time pressure. Disability is not always permanent either - a broken arm, an eye condition or simply ageing can temporarily change how someone interacts with a product, so designing for the full range of abilities benefits a far wider group than it first appears. In many jurisdictions, including Australia, accessibility is a legal obligation under disability discrimination law. Designing for it from the start is far cheaper than remediating an inaccessible product later.
Accessibility design best practices
Build accessibility into the design phase rather than treating it as a final audit. Use semantic structure so assistive technology can interpret content correctly. Do not rely on colour alone to convey meaning, and ensure interactive elements have visible focus states and clear, descriptive labels. Make tap targets large enough to use comfortably, and provide text alternatives for any non-text content. Test with real assistive tools such as screen readers and keyboard-only navigation, and where possible include people with disabilities in usability testing rather than relying solely on automated checkers, which catch only a fraction of real issues.
How PixelForce approaches accessibility in design
At PixelForce, accessibility is part of how our in-house team designs and builds, starting in Phase 1 Scoping and Design where structure and colour decisions are made. It is a core consideration in our UX UI design work, where designs are checked against WCAG AA before they reach development, then verified again during Phase 2 QA. We treat accessibility as a baseline of good product design rather than an optional add-on, because a product that excludes part of its audience is simply not finished.

Frequently asked questions
Usability is about how easy and pleasant a product is to use for people in general. Accessibility is specifically about whether people with disabilities can use it at all. The two overlap heavily: an accessible product is usually more usable for everyone. However, a product can be highly usable for most people while still being inaccessible to someone relying on a screen reader.
WCAG stands for the Web Content Accessibility Guidelines, an internationally recognised standard for making digital content accessible. It is organised around four principles - perceivable, operable, understandable and robust - and defines three conformance levels: A, AA and AAA. Most products aim for AA, which balances strong accessibility with practical achievability and is commonly referenced in legal and procurement requirements.
In Australia, the Disability Discrimination Act makes it unlawful to provide goods, services or facilities in a way that discriminates against people with disabilities, and this has been interpreted to cover digital products. Government services are required to meet WCAG standards, and private organisations face legal risk if their products are inaccessible. Designing for accessibility from the outset is the safest and most cost-effective approach.
When accessibility is built in from the start, the additional cost is small because it is part of normal design and development decisions. The expense arises when it is ignored and a product has to be retrofitted later, which can mean reworking layouts, colour systems and components. Designing accessibly from the beginning is far cheaper than remediation and also widens the audience the product can serve.
