Title: How Users with Tremors Navigate Small Touch Targets
Introduction
Digital accessibility is more than a legal requirement—it's a commitment to inclusion. Millions of individuals with motor impairments, including those experiencing tremors from conditions like Parkinson’s disease, essential tremor, or multiple sclerosis, navigate the digital world every day. Yet, many websites and applications unintentionally create barriers that make this experience frustrating or impossible.
One common and overlooked barrier? Small touch targets.
In this comprehensive guide, we explore how users with tremors interact with digital interfaces, the challenges posed by small touch targets, key accessibility standards related to motor impairments, and how digital teams can build more inclusive, user-friendly experiences from the ground up.
We’ll also explain how allyWay supports developers, agencies, and business owners in reducing barriers and optimizing digital accessibility—without promising compliance, but by being a smarter, business-friendly solution in your accessibility toolkit.
Let’s dive deeper into how thoughtful design, inclusive tools, and accessible practices can empower individuals with motor impairments to fully participate online.
Understanding Tremors and Motor Impairments in a Digital Context
Before we make the digital world more accessible for users with tremors, it’s important to understand what tremors are and how they impact user behavior.
What Are Tremors?
A tremor is an involuntary, rhythmic muscle contraction leading to shaking movements in one or more parts of the body. Tremors can be caused by a variety of conditions, including:
- Parkinson’s disease
- Essential Tremor
- Multiple sclerosis
- Traumatic brain injury
- Stroke
Tremors may affect the hands, arms, head, vocal cords, torso, and legs. For digital usage, hand tremors tend to impact precision—such as tapping a small button on a smartphone or clicking a close icon on a modal window.
Common Digital Barriers Faced by Users with Tremors
Users with tremors may struggle with:
- Small buttons and interactive elements: Hard to press accurately without triggering nearby elements.
- Closely spaced links or form controls: Difficult to differentiate and select.
- Time-limited interactions: Challenging to complete within a preset time frame.
- Non-customizable interfaces: Lack of size scaling, spacing adjustments, or input alternatives.
Why Small Touch Targets Matter in Accessibility
Touch target size isn’t just a matter of comfort—it's essential for access.
Under the Web Content Accessibility Guidelines (WCAG) 2.2, specifically:
WCAG 2.2 — Success Criterion 2.5.8: Target Size (Minimum)
This criterion specifies a minimum size of 24 by 24 CSS pixels for touch targets. If smaller targets are used, sufficient spacing must be provided around them.
Why Minimum Target Size Is Important
- Improves hit accuracy
- Reduces errors and false inputs
- Increases ease of navigation
- Enhances the overall mobile experience—not just for users with tremors
This is not only a WCAG recommendation but also reflected in EN 301 549, the European Union accessibility specification, and influences practices under EAA (European Accessibility Act) and ADA (Americans with Disabilities Act).
Ensuring appropriately sized touch targets is a low-effort, high-impact change that contributes to a more inclusive site interface.
How Users with Tremors Navigate Websites with Small Touch Targets
Let’s walk through a typical experience of a user with motor impairments encountering a site with poor accessibility.
Scenario: Online Shopping on Mobile
- Navbar interaction: The user attempts to tap the menu icon but frequently misses it due to its small size and location near the screen edge.
- Product filters: Sliders, toggles, and small radio buttons in the sidebar offer no alternative input, causing selection frustration.
- Checkout experience: Repeated mistakes with form entry due to closely spaced input fields; time-sensitive CAPTCHA causes further issues.
- Final result: User abandons cart and session, facing both emotional and physical exhaustion.
Real-World Workarounds Users May Attempt
- Using a stylus (though this adds hardware dependency)
- Relying on voice-to-text or speech input systems
- Switching to desktop (if mobility allows) for better control
- Zooming in for better touch accuracy (disrupting the layout)
But workarounds are not solutions. The responsibility lies in inclusive design principles.
Designing for Touch Accuracy: Best Practices
1. Follow WCAG 2.2 Guidelines
Use the 24px minimum target size or a clear 8px surrounding area between smaller elements. Ensure touch targets aren’t placed too close to one another.
2. Implement Clear Visual Indicators
- Add visible focus states
- Use large icons with generous padding
- Design distinct interactive elements (vs passive content)
3. Support Alternative Navigation
- Enable full keyboard navigation
- Support voice instructions for smart assistants
- Allow toggling or customizing interaction behaviors
4. Avoid Timeouts or Provide Flexibility
Users should be able to request more time or pause interactions as needed.

Inclusive Design vs. Reactive Fixing
One major mistake brands make is waiting until an accessibility issue has been reported—or worse, until legal action is taken. Designing inclusively from the start improves brand trust and user retention.
Reactive Approach
| Trait | Implications |
|---|---|
| ✓ Wait for user complaints | Damaged brand credibility |
| ✓ Patch issues based on feedback | High developer costs later |
| ✓ Increased risk of inaccessibility claims | Legal and reputational risk |
Inclusive by Design Approach
| Trait | Benefits |
|---|---|
| ✓ Builds accessibility into UI from day one | Reduced retrofitting cost later |
| ✓ Supports broader usability for all devices | Conversion boosts and improved UX |
| ✓ Positions your brand as inclusive | High trust among diverse user bases |
Making the Business Case for Accessible Touch Design
Including users with motor impairments isn’t just the right thing to do—it yields tangible ROI.
Why Accessibility Pays Off
- Expanded audience reach → Millions of users with motor disabilities rely on accessible interfaces.
- Improved SEO → WCAG-friendly sites rank better due to cleaner markup and better usability signals.
- Reduced abandonment → Fewer barriers lead to higher engagement and conversions.
- Better usability for all → Larger touch targets improve experience for mobile users with large fingers, aging users, and more.
- Alignment with global laws → While allyWay does not guarantee legal compliance, improving accessibility supports your alignment with ADA, EAA, WCAG, and EN 301 549.
Practical Checklist for Touch Accessibility Optimization
Use this checklist to assess whether your touch interface is friendly for users with tremors:
✓ Are all buttons at least 24px x 24px with 8px spacing around?
✓ Are touch elements not clustered or overlapped?
✓ Is there a visual focus outline or hover/focus indicator for interactive areas?
✓ Is keyboard navigation offered across all components?
✓ Are form fields spread out with proper labels and error handling?
✓ Is your website tested across mobile devices for tap accuracy?
If you said “no” to any of these, allyWay can support your accessibility enhancement strategy with tools and visual features to bridge the gap efficiently.
FAQ: Small Touch Targets and Accessibility
What is considered a “small touch target”?
Anything smaller than 24×24 CSS pixels—especially if it's surrounded by other interactive elements—is considered less accessible for motor-impaired users.
How do tremors impact website use?
Tremors reduce touch precision, leading to erroneous selections, difficulty tapping small icons, increased cognitive load, and frustration.
Does increasing touch target size affect design negatively?
Not at all. Well-designed interfaces with larger, accessible buttons look better—clean, spacious, and user-friendly, especially on mobile.
Can allyWay automatically fix small touch targets?
No, allyWay is not an auto-compliance tool. However, it supports accessibility efforts by identifying such issues and offering functional enhancements via its platform.
Will this help with legal accessibility requirements?
allyWay assists in accessibility optimization and helps businesses align with requirements like WCAG, EN 301 549, and ADA, but it does not guarantee compliance.
Conclusion: Make Every Tap Count
Users with tremors face unnecessary friction when navigating websites that rely on small, poorly-spaced touch targets. These challenges are solvable—with thoughtful design, clear standards, and purpose-driven tools.
