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.

82/100

Mobile Friendly5 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.

width=device-width, initial-scale=1, minimum-scale=1

✅ Excellent readability: 24px body text is ideal for all devices.

✅ Optimal line spacing: 1.60 ratio (ideal range 1.4–1.6).

❌ Very complex text: Flesch score 21/100. Consider shorter sentences and simpler words.

⚠️ Partial contrast: 11 elements below WCAG AA threshold (min 3.3:1).

❌ Missing H1: Every page should have exactly one H1 element for SEO and accessibility.

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