Apple's iPad Mini is a smaller clone of the iPad 2 in more ways than we'd want. In JavaScript, the window.navigator object exposes the same values for the Mini and iPad 2. My tests so far to detect the difference have not lead to success. Why is this important? As the iPad Mini and iPad 2 screens are identical in pixels but vary in actual size (inches / centimeters), they vary in PPI (pixels per inch). For web applications and games to offer a friendly user interface, certain elements are adjusted in size relative to a user's thumb or finger position, thus, we may want to scale certain images or buttons to provide for that better user experience. Things I have tried so far (including some pretty obvious approaches): window.devicepixelratio CSS element width in cm unit CSS media queries (such as resolution and -webkit-device-pixel-ratio ) SVG drawings in similar units Doing all sorts of CSS webkit transforms for a set time and counting rendered frames with requestAnimFrame (I was hoping to detect a measurable difference) I'm fresh out of ideas. How about you? Update Thanks for the responses so far. I would like to comment on people voting against detecting iPad mini versus 2 as Apple has uhm, one guideline to rule them all. Okay, here's my reasoning why I feel it really makes all sense in the world to know if a person is using an iPad mini or a 2. And do with my reasoning what you like. The iPad mini is not only a much smaller device (9.7 inch versus 7.9 inch), but its form factor allows for a different usage. The iPad 2 is usually held with two hands when gaming unless you're Chuck Norris . The mini is smaller, but it is also much lighter and allows for ga
