Webpage Tap Target Size Tester
Checks links and buttons are large enough to tap accurately on a touchscreen.
Runs a real Chromium page load — usually takes 5–15 seconds.
What this tool checks
Tap targets are large enough
Rendered on a 390px-wide mobile viewport, counts interactive elements smaller than 44×44 CSS pixels. Links inside a sentence and visually hidden elements (such as skip links) are excluded, as in WCAG 2.5.5.
Why it matters: Small or tightly-packed tap targets are hard to hit accurately on a touchscreen, causing mis-taps and frustration.
If it fails: Make buttons and links at least 44×44px with adequate spacing between them.
