Title: Touch Targets: Designing for Motor Impairments
Introduction
In an increasingly digital world, inclusive design is not just a best practice—it's a necessity. As more interactions take place online, ensuring that websites and applications are accessible to individuals with motor impairments is a key component of digital accessibility. One of the most effective ways to begin improving accessibility for users with limited mobility is by addressing touch targets.
Touch targets refer to the interactive elements on a digital interface, such as buttons, links, and form fields. When these elements are designed with appropriate size, spacing, and functionality, they can significantly enhance the user experience for people with motor impairments. Conversely, poorly designed touch targets can create frustrating barriers, reduce completion rates, and exclude entire user groups.
This article dives deep into the importance of designing accessible touch targets—from practical design considerations to applicable accessibility standards like WCAG and EN 301 549. We’ll also explore how tools like allyWay can support your efforts in reducing barriers and making your digital content more inclusive.
Why Touch Target Accessibility Matters
Motor impairments affect an individual’s ability to make precise movements. This can be due to conditions such as cerebral palsy, Parkinson’s disease, arthritis, spinal cord injuries, or the after-effects of strokes. For these individuals, navigating a touchscreen or even using a mouse can be challenging, especially when interface elements are too small or too close together.
Problems Created by Inaccessible Touch Targets:
- Difficulty selecting small buttons or links
- Accidental taps due to lack of spacing between elements
- Inability to complete forms or transactions
- Fatigue caused by repeated, failed attempts to interact with UI elements
Designing with these challenges in mind results not only in better accessibility but also in a more usable experience for all. After all, even users without disabilities benefit from larger, well-spaced touch targets—particularly on mobile devices.
Accessibility Guidelines for Touch Targets
Global web accessibility standards have emphasized the importance of making touch targets usable for everyone. Here’s how some of the most influential guidelines approach this issue:
WCAG 2.2: Web Content Accessibility Guidelines
The WCAG 2.2, maintained by the W3C, extends guidance on touch target sizing in Success Criterion 2.5.8 – Target Size (Minimum).
Requirements:
- Touch targets should be at least 24 by 24 CSS pixels.
- Exceptions apply for inline links or where spacing provides a sufficient buffer.
EN 301 549 & European Accessibility Act (EAA)
EN 301 549, which supports the European Accessibility Act, closely aligns with WCAG standards, including those for motor accessibility. It requires interface elements to be operable and assistive-technology-compatible.
Key Considerations:
✓ Ensure all interactive components are distinguishable
✓ Provide ample spacing between interactive elements
✓ Avoid requiring complex gestures like multi-tapping or swiping
ADA Compliance (U.S.)
While the Americans with Disabilities Act (ADA) does not specify technical requirements for touch targets, courts increasingly interpret websites as places of public accommodation. Therefore, failure to make interactive content accessible could be viewed as discrimination under the ADA.
→ Designing according to WCAG and usability best practices can help support ADA accessibility efforts without legally guaranteeing compliance.
Best Practices for Designing Accessible Touch Targets
Designing accessible touch targets is a blend of usability, accessibility guidelines, and thoughtful layout. Here’s what you need to consider:
1. Size Matters
Larger touch targets are easier to tap accurately. Aim for a minimum of 44px x 44px (Apple’s Human Interface Guidelines) even though WCAG 2.2 allows 24px x 24px.
Pro Tips:
- Use padding to increase touchable areas without changing visual design.
- Prioritize size for frequently used actions (e.g., “Buy Now”, “Submit”).
2. Provide Sufficient Spacing
Crowded interfaces increase the risk of accidental taps—especially for those with tremors or reduced fine motor control.
Use generous padding and margins to:
✓ Prevent accidental activations
✓ Reduce cognitive strain
✓ Enhance mobile usability
3. Avoid Complex Gestures
Interactions that require double-tapping, swiping, or dragging can be difficult for users with motor impairments.
Simplify with options like:
- Single tap activation
- Visible focus indicators
- Keyboard accessibility alternatives
4. CTA Design & Button Placement
Calls-to-action (CTAs) and buttons should be easy to locate and operate. Good design puts operable elements where they can be naturally reached—especially on mobile devices.
Consider:
✓ Bottom-center or bottom-right placement on mobile
✓ Avoiding positioning interactive elements near screen edges
5. Use Visual and Programmatic Feedback
Let users know when an element is active or being interacted with. Use focus indicators, hover effects, and ARIA roles to create an inclusive experience.

Real-World Accessibility Use Cases
Use Case 1: Online Retailer
A fashion retailer noticed reduced mobile checkout conversions. By analyzing their interface with allyWay’s AI audit, they discovered that the “Add to Cart” buttons were too small and too close together. Adjustments were made to increase button size and refine layout spacing. Result: a 20% boost in completed checkouts.
Use Case 2: Municipal Website
A city government wanted to provide better digital services to residents with disabilities. Integrating allyWay’s accessibility profiles allowed users with motor and vision impairments to navigate more easily, reducing helpdesk requests and supporting their compliance efforts under the EAA.
Touch Targets in the Larger Context of Inclusive Design
Accessible touch targets are just one part of a comprehensive accessibility strategy—a strategy that also includes clear typography, logical navigation, and assistive technology compatibility.
Other crucial components include:
- Proper heading structure
- Keyboard navigation integration
- Alternative text for images
- Form field labeling
- ARIA landmarks and roles
These elements all interact synergistically. When combined, they lower access barriers and promote usability for everyone.
