Please use this tool on your desktop computer/laptop. If this tool is tested on a mobile device, you will see results that show you the mobile version of your site rather than the responsive version which is dependent on screen resolutions not device. Please click here to read more about the difference between adaptive vs. responsive.
Results will differ for sites that are adapted to mobile device. Our Responsive tool incorporates a flexible foundation into its structure and shows you how your site will look based on screen size rather than device type. This is why many sites that are mobile adaptive, display differently on our tool.
