2.5.5: Target Size (Enhanced)

What it means

Target size at AAA is at least 44 by 44 CSS pixels for pointer inputs, with limited exceptions. Large touch targets reduce mis-taps for everyone.

Small icons and tight link clusters fail this level.

How to fix it

• Size buttons and links to at least 44×44px or add padding to hit area.
• Space adjacent targets so users do not tap the wrong control.
• Increase icon button padding even when the icon graphic is smaller.
• Check mobile layouts where footer links crowd together.

Quick examples

• Good: Icon buttons are 44px square with adequate spacing between them.
• Bad: Pagination uses 12px number links with no padding.
• Good: A table row action menu has a large tap target at the row end.
• Bad: Social icons are 20px with one pixel gap between them.
