iPhone 18 Pro Max Testing FAQs

Common questions about responsive web design on iPhone 18 Pro Max.

What are the CSS safe area insets for iPhone 18 Pro Max?

The iPhone 18 Pro Max uses env(safe-area-inset-top) for Dynamic Island or Home Button clearance, and env(safe-area-inset-bottom) for the swipe-to-home indicator. Always set font-size: 16px minimum on inputs to prevent iOS Safari auto-zoom.

What is the viewport resolution of the iPhone 18 Pro Max?

The iPhone 18 Pro Max has a CSS viewport of 440px × 956px at a device pixel ratio of 3x. The physical resolution is 1320 × 2868 pixels.

Why does my website zoom in on iPhones?

iOS Safari auto-zooms into form inputs with font-size under 16px. Always set font-size: 16px or larger on all inputs. Also ensure your viewport meta tag includes width=device-width, initial-scale=1.0.
