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.
