Title: The Importance of Large Touch Targets on Mobile Devices
Introduction
As our world becomes increasingly digital and mobile-first, the demand for inclusive, accessible digital experiences has never been more important. Mobile devices have transformed how users interact with websites and web applications—but smaller screens and compact navigation structures present unique challenges, especially for users with accessibility needs. One often overlooked but crucial aspect of mobile accessibility is the size of interactive elements, commonly referred to as touch targets.
This article explores the importance of large touch targets on mobile devices, their role in accessible design, and how websites can improve usability across all user demographics. We'll also discuss accessibility standards like WCAG and EN 301 549, showcase industry best practices, and demonstrate how a tool like allyWay can support and optimize your accessibility efforts without overpromising legal compliance.
Let’s explore why the size of a button could be the difference between someone accessing content and someone being excluded from it.
What Are Touch Targets?
In digital interface design, "touch targets" refer to the tappable or clickable areas of interactive elements—like buttons, links, checkboxes, and icons. On touchscreens, especially smaller ones like smartphones or tablets, it's essential that these elements are large enough to be tapped accurately and easily.
A common misconception is that users are always young, tech-savvy, and able-bodied—but this myth fails millions. People with mobility impairments, tremors, low vision, or even larger fingers can struggle with buttons that are too small or too closely spaced.
Why Touch Target Size Matters in Mobile Accessibility
Whether users are filling out a form, navigating a product catalog, or trying to complete a purchase, small touch targets can create usability and accessibility barriers by:
- Increasing error rates and accidental taps
- Slowing down user interactions
- Causing user frustration and abandonment
- Excluding users with motor or visual impairments
And, importantly, these aren’t just inconveniences—they can be violations of emerging accessibility requirements and directly contradict digital inclusion principles.
Accessibility Standards That Mention Touch Targets
WCAG 2.2 Success Criterion 2.5.8 – Target Size (Minimum)
The latest update to the Web Content Accessibility Guidelines (WCAG) 2.2 added a specific criterion related to touch targets:
2.5.8 Target Size (Minimum): Touch targets should be at least 24 by 24 CSS pixels apart unless there's a technological or design constraint.
This guideline ensures that users can interact with website elements comfortably without unintentionally activating surrounding content.
EN 301 549 and the European Accessibility Act (EAA)
The EN 301 549, the European standard harmonizing web accessibility regulations in the EU, aligns closely with WCAG. The European Accessibility Act (EAA) reinforces these guidelines across mobile apps and digital services.
Failure to address minimum touch targets could be seen as not supporting best practices in accessibility—impacting the inclusiveness of your digital experience.
Accessibility and ADA Considerations
In the United States, the Americans with Disabilities Act (ADA) doesn’t provide specific pixel measurements for touch targets, but it does expect public-facing digital experiences to be usable by people with disabilities. Following WCAG ensures you’re aligning your content with widely recognized accessibility benchmarks.
Real-World Impacts of Poor Touch Target Design
Situations Where Small Touch Targets Fail
-
Login with Mobile Keyboard Open
Tiny login buttons under a virtual keyboard become impossible to reach. -
Navigation Menus on Responsive Layouts
Menu icons that are too close make it hard to select the correct page. -
Checkboxes in Forms
Users with tremors struggle to mark selections precisely. -
Checkout or Submit Buttons
Inaccessible checkout buttons mean abandoned carts and lost revenue.
These aren’t fringe errands—they’re core parts of a user’s journey on your website or app.
Best Practices for Designing Accessible Touch Targets
Designing effective, accessible touch targets doesn’t require a complete UI overhaul. Instead, it requires intention, testing, and the right support tools. Here’s how you can design better touch targets on your digital interfaces:
Recommended Touch Target Sizes
| Standard | Minimum Size | Notes |
|---|---|---|
| WCAG 2.2 | 24 x 24 CSS pixels | Applies unless there's adequate spacing or labels |
| Apple iOS Guidelines | 44 x 44 points | Apple's Human Interface Guidelines recommendation |
| Android Guidelines | 48 x 48 dp | Material Design outlines optimal tap targets |
Design Tips
✓ Ensure at least 24x24px for all tap targets
✓ Provide ample spacing between adjacent clickable elements
✓ Avoid nesting multiple touch targets inside each other
✓ Use high-contrast labels and feedback (like animations or color changes)
✓ Make hard-to-tap elements larger on smaller viewports
✓ Group elements like form fields intelligently
✓ Add padding—larger clickable areas don't mean larger visual buttons, just more tap area

Why Businesses Should Care About Accessible Touch Targets
1. Improved Usability for Everyone
Designing for touch targets doesn’t just help people with disabilities—it improves the user experience for all:
- Parents holding a child while using one hand
- Users accessing your site in a moving vehicle
- Elderly users with reduced dexterity
2. Lower Bounce Rates and Higher Conversion
Frustrated users leave. Conversion-optimized touch targets reduce friction, resulting in:
- Increased form submissions
- Higher eCommerce sales
- Longer session duration
3. Risk Mitigation
By aligning with WCAG and accessibility best practices, you reduce the exposure to digital exclusion risks.
While no tool guarantees compliance, platforms like allyWay help document your efforts and streamline optimization in a business-friendly, user-first way.
Addressing Touch Target Accessibility on WordPress
For the millions of businesses using WordPress, ensuring accessible touch targets is both achievable and practical. Pair your preferred page builders (e.g., Elementor, WPBakery) with accessible-friendly plugins and follow these guidelines:
WordPress Tips for Touch Target Accessibility
- Avoid linking images without appropriate alt and aria-labels.
- Use large, well-spaced buttons in mobile responsive themes.
- Audit your front-end output using developer tools to verify tap target sizes.
- Use ARIA roles purposefully and only when needed.
- Run accessibility audits with tools like allyWay to spot missed tap area issues.
Unlike traditional accessibility plugins, allyWay integrates directly into your existing web stack and supports both static websites and dynamic platforms like WordPress.
Quick Touch Target Evaluation Checklist
Use this quick checklist to assess your touch target accessibility:
- □ Are all tap targets at least 24 x 24 CSS pixels?
- □ Is there sufficient spacing between interactive elements?
- □ Do all touch targets have unique visible labels?
- □ Have all elements been tested using a screen reader?
- □ Is your mobile site or app testable with only a keyboard or switch input?
If you answered “no” to any of these, it might be time to run an audit through a trusted tool like allyWay.
Frequently Asked Questions
What is the minimum recommended size for mobile touch targets?
WCAG 2.2 recommends a minimum target size of 24 by 24 CSS pixels. Apple and Android recommend slightly larger touch areas to accommodate user needs.
Can small touch targets be accessible if properly labeled?
Not always. Even if technically accessible, very small targets can still be hard to tap or differentiate, especially for users with impairments or less dexterous devices.
Does allyWay help identify touch target issues?
Yes, allyWay’s AI-powered audit recognizes insufficient touch target sizes and provides actionable suggestions for improving accessibility across mobile and desktop interfaces.
Do you need to change the visual size of a button, or just the tap area?
You can increase the interactive area (padding) without increasing the visible size of the element. This ensures your UI/UX remains sleek while remaining functional for all.
Is following WCAG enough to ensure legal protection?
There is no platform or solution that can guarantee legal compliance. However, adhering to WCAG and using tools like allyWay supports your accessibility efforts and demonstrates good faith in meeting accessibility expectations.
