We are faced with such a striking diversity of devices and resolutions these days, that it is quickly getting impractical, if not impossible, to design different versions of a website for each new invention.

The solution of this problem is responsive design, which suggests that the visual elements of a website should respond to the user’s behavior and provide the most optimal user experience based on the screen size and the platform of the user’s device.

Nearly everyone wants a website that will be compatible with with all screen resolutions, which is why responsive design has caught on among web designers and web developers. When designing and developing a website, you obviously want to see what it is going to look like on different devices.

The best way to check your website’s responsiveness is to use one of responsive design testers available online. Our responsive design checker does its task very well: it lets you see exactly how the visual content of your website responds to different screen resolutions. The way this tool works is more than simple. All you have to do is to type in your website’s URL in the form above, click the GO button, and then select any of the supported devices.

Bear in mind that our responsive web design checker can’t show how different technologies work within your website, so unfortunately, there isn't a way you can use it to check things like video players or Flash.

It is designed to help you and your clients test the behavior of the visual content of your website throughout various types of devices. Oh, and did we mention that our mobile responsive design checker is 100% free?
