A 7.85-inch iPad would be 40% larger than existing 7 inchers

How much, you might wonder. Truth is that a 7.85-inch iPad mini would be nearly 40% larger than 7-inch tablets.
It’s all simple maths. The screen area of a 7.85-inch tablet comes at around 30 square inches, which is nearly 40% more than the 22 square inches you get on 7-inch slates.
Check out the picture below, showing how different aspect ratios and diagonal screen sizes measure in terms of pure screen area available. So would it be appropriate to call the 7.85-inch mini iPad one of the 7-inch tablets? Not at all, but comparing it with seven inchers is, of course, inevitable.

Doesn't exactly look like 1/2 of a standard iPad....

are you for real?? the different between 7 and 7.7 is just an extra 10%, so the different between 7 and 7.85 is not more than 13%. if what you are saying is true, then the 9.7 inch tab is 120% bigger than the 7 inch which means one 9.7 ich tab is even bigger than two 7 inch tabs which is clearly not true. you can even look at it with naked eye (without using math) 40% is nearly 50% extra, does it look from the image that the 7.85 is 1.5 X the size of the nexus 7???

> the different between 7 and 7.7 is just an extra 10%, so the different between 7 and 7.85 is not more than 13%. Because you need to understand geometry -- for a given DIAGONAL, the area of a rectangle is maximized when it is a square. That is to say, the more square-like the device, the more display area, other things being equal. A square has a aspect ratio of 1.0 meaning the mini iPad with a 4/3 aspect ratio has far more display area than the same tablet with a 17/10 or 16/9 aspect ratio for the same diagonal, respectively. > if what you are saying is true, then the 9.7 inch tab is 120% bigger than the 7 inch which means one 9.7 ich tab is even bigger than two 7 inch tabs which is clearly not true. Do the math. Steve Jobs pointed out that the iPad had twice the display area of the first wave of 7" android tablets. The best way to prove this is using calculus. However, if you understand trigonometry, you will know that if you bisect a square diagonally to form two isosceles triangles, the angles are 45 degrees, 90 degrees and 45 degress for each triangle, respectively. The key point is the tangent of 45 degrees is 1.0. The area of a square is simply twice the area of each isosceles triangle (recall the area of a triangle is 0.5*base*height). When OEMs use narrow displays, the tangent is no longer 45% and the area of each isosceles triangle is smaller, respectively, thus reducing the total area of the rectangular screen. I have been stating for a long time that android devices with large diagonals tell us very little about the display area. Most android devices like HTC have long and narrow screens, respectively.

That makes the rest of the tablet 40% larger too, so those of you who want to smaller tablet remember to take that into account

So, what you are saying is that a bigger tablet is ..... bigger? Pure genius!!

I'm saying that a Apple made a tablet with 40% more surface across the board, they didn't just fit 40% more screen on the same surface area. So, if you're looking for a tablet that's kindle-sized, look elsewhere as Apple's mini-pad will be 40% bigger and might not fit in your purse.
