About Am I Responsive

A time saving exercise by Justin Avery for RWD Weekly Newsletter

I take a lot of screen shots of the various device breakpoints for responsive design and it takes a while to prepare them. This tools allows me to get what I need quickly, and hopefully it can be helpful for showing your more visual clients what you mean by responsive design when a suite of products isn't at the ready.

This is not a tool for testing, it is really important that you do that on real devices. This instead is a tool for quick screenshots (for me) and to visually allow people to “get” what you mean in client meetings.

Viewports

Desktop 1600x992px scaled down to scale(0.3181) Laptop 1280x802px scaled down to scale(0.277) Tablet 768x1024px scaled down to scale(0.219) Mobile 320x480px scaled down to scale(0.219)

A note on the viewports

The viewports I have chosen are based on the devices that were a part of the responsive PSD layout I previously bought, and yes they are all Apple. Apologies to all the Android fans out there, I'm sure a few of you have the “Android has a bigger market share” argument in mind but although you're right I just didn't have that suite of images when I started. If there's enough of a desire I could do a suite of other products, but I'm just not sure if adding those will improve the basic function of the tool.
