Envisaging the size of the Kindle DX display

I'm trying to envisage the size of the Kindle DX display:
It's 9.7" diagonally (246.38 mm) and given that it's probably sized in the same ratio as A series ISO 216 paper (think A4 paper), that would make it 7.92" x 5.6" (201.17 mm x 142.25 mm), which is a little smaller than the size of A5 paper - basically a sheet of A4 (or Letter sized) paper cut in half across it's length.
Not as large as I thought at first!

It is now in the E-book Reader Matrix, and the screen is almost exactly the same size as the entire Kindle 2. As you suggest, the ~10" screens are essentially half a letter/A4 page - although the 9.7" screen is the smallest of this class (compare to the DR1000S in the adjacent column).

According to the kindle site the aspect ratio is 1200x824. Doing the math with that ratio it gives results very similar to yours :
20.28cm x 13.93cm
(diagonal 24.6cm).

Assuming the pixels will be 1:1 square of course
I used the ratio of 1200:824 - which is 1:1.46, similar to A series 1:sqrt(2) - and got back 139.47 mm x 203.11 mm (5.49" x 8" for the non-SI among us - it's interesting; it was 8" exactly..) - diagonal 9.7" (246.38 mm)
