I’m always on the lookout for a good mobile device testing tool.

With so many different mobile devices out there and the absolute need for developing responsive websites, testing a web layout is essential.

Here is a quick and easy browser based testing tool that you’ll be sure to bookmark!

Check it out:

Screenquries

Screenqueries is ridiculously easy to use.

Take the 8BIT About page, for example.

Here is how it looks in a standard browser:

Since the 8BIT website is using a child theme via Standard Preview 3, the 8BIT website is completely responsive.

Here’s how it looks with an iPhone:

And here’s how it looks in a landscaped iPad view:

Pretty slick, right?

Screenquries has presents for both views, standard and landscape, as well as the following devices:

Smartphones

• Apple iPhone
• Samsung Galaxy Note, Infuse 4G, Galaxy S II, Nexus 4 (Google)
• HTC Evo & Sensation
• Blackberry Torch, Bold & Curve
• LG Optimus 4X HD & Spectrum
• Nokia Lumia and Motorla DROID

Tablets

• Apple iPad
• Samsung Galaxy Tab 10.1 & 7.0
• Sony Tablet P & S
• BlackBerry Playbook, Asus Eee Pad, Amazon Kindle Fire, Viewsonic ViewPad 7, HO Slate 500, Motorola Xoom & HTC Flyer

Screenqueries is accepting submissions for other devices, but even still, if you don’t see a device you want tested, you can easily adjust and use custom dimensions for testing.

Again, this is all from your browser.

Learn more, bookmark it, and give it a try on the Screenquries website.
