Common viewport meta issues this tool can reveal.
Viewport meta issues can affect how a page scales on mobile devices and how usable it feels on smaller screens.
Missing viewport tag
A missing viewport tag can cause mobile browsers to render the page as a desktop-width layout.
Missing width=device-width
width=device-width tells mobile browsers to match the page width to the device width.
Zoom restrictions
Viewport settings that disable zoom can hurt accessibility and usability.

What is a viewport meta tag?
A viewport meta tag tells mobile browsers how to size and scale a webpage on different screens.
Why is width=device-width important?
width=device-width helps the page fit the actual device width instead of rendering as a large desktop canvas.
Should I disable zoom?
Usually no. Disabling zoom can create accessibility problems for users who need to enlarge text or content.
