Mobile Compatibility

Viewport & Responsive Test

Tests how well your website works on mobile devices. Checks viewport configuration, responsive layout, touch targets, font readability, and simulates rendering across different screen sizes.

58/100

Mobile Friendly1 breakpoint

Viewport Meta

The viewport meta tag tells mobile browsers how to scale the page. Without it, mobile devices render at desktop width.

Responsive Design

Uses CSS media queries or flexible layouts to adapt content to different screen sizes automatically.

Touch Icons

Apple touch icons and favicons displayed when users add the site to their home screen on mobile devices.

Readable Font Size

Base font size should be at least 16px on mobile to ensure text is readable without zooming.

Relative Units

Using em, rem, %, or vw instead of fixed px values allows content to scale properly across screen sizes.

No H-Scroll Risk

No elements wider than the viewport that would cause horizontal scrolling on mobile devices.

Tap Targets OK

Interactive elements (buttons, links) are at least 48x48px with enough spacing to prevent accidental taps.

No Fixed Widths

No elements with fixed pixel widths that could overflow on smaller screens and break the layout.

Viewport

width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no

❌ Critical: 11px body text is too small. Minimum 14px, recommend 16px+.

⚠️ Wide line spacing (3.27). 1.4–1.6 is optimal for body text.

⚠️ Partial contrast: 19 elements below WCAG AA threshold (min 2.6:1).

❌ Broken heading hierarchy: 4 level skip(s). Screen readers rely on sequential headings (h1→h2→h3).

✅ Strong hierarchy: Headlines are 3.3x larger than body text.

⚠️ Missing font-display: swap — users may see invisible text while fonts load (FOIT).
