Link Cluster With Targets Spaced Too Close Together

2.5.8 — Target Size (Minimum)

Scenario

Setting

A ticket marketplace's seat-selection map

What’s wrong

Link clusters where undersized targets have no spacing exemption (centers closer than 24px).

Example

.icon-button { width: 16px; height: 16px; }

Why it matters

People with tremor or larger touch contact areas, and anyone tapping on a moving vehicle.

How to test

Measure a cluster of adjacent text links: if their centers are closer than 24px apart with no spacing exemption applicable, it fails.

How to fix

The target must be at least 24x24 CSS px, or have enough spacing that a 24px circle around its center overlaps no other target, or a compliant equivalent control must exist. .icon-button { width: 24px; height: 24px; } Interactive targets need at least 24 by 24 CSS pixels, or enough spacing that adjacent targets don't overlap that minimum.

Outcome

On a ticket marketplace's seat-selection map, this barrier is gone for people with tremor or larger touch contact areas — they can finish what they came here to do.

Who is affected

People with tremor or larger touch contact areas, and anyone tapping on a moving vehicle.
