Widescreen is in the ratio 16 wide by 9 high. Standard is 4 wide by 3
high. The screen size is measured across the diagonal and the ratio is
18.35 for widescreen and 5.0 for standard. So you have a choice between
a 15 inch widescreen or a 15 inch standard screen where these are
diagonal dimensions. The widescreen height will be 15/18.35 x 9 = 7.36
inches; the width will be 15/18.35 x 16 = 13.08 inches. The standard
screen will be 15/5 x 3 = 9 inches; the width will be 15/5 x 4 = 12
inches.
Standard 15 inch screen h = 9, w = 12 ; UXGA res = 1600 x 1200
Widescreen 15 inch h = 7.36 w = 13.08. WUXGA res = 1920 x 1200
So the same size photo on a standard screen, compared to a widescreen
will have a physical ratio of 9/7.36 = 1.22 or almost 25% larger on a
standard screen of the same diagonal measurement as a widescreen.
The move to widescreen is only predicated on the cost of the screen: in
the 15.4 inch widescreen, 7 widesceens per sheet of LCD can be made
while only 4 standard 15 inch screens can be made. This is a huge
manuafacturing savings and is the reason that laptop prices are falling
dramatically.
Going back to the math, the 15 inch widescreen is actually the
dimensional equivalent of a standard screen 7.4 inches high, or 7.4/3 x
5 = 12.3 inches diagonally. There are laptops with 12 inch screens in
standard format; these are difficult for photo work as even a short
photo session will confirm.
