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.
B
76/100
Mobile Friendly9 breakpoints
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.

✅ Excellent readability: 16px body text is ideal for all devices.

⚠️ Tight line spacing (1.00). Increase to 1.4–1.6 for better readability.

✅ WCAG AAA contrast: All text meets 7:1 ratio (min 9.9:1).

✅ Strong hierarchy: Headlines are 2.5x larger than body text.

✅ Modern fluid typography: clamp() with rem units ensures zoom accessibility (WCAG 1.4.4).

✅ System fonts: Zero font loading delay — best possible LCP impact.
