How do you figure out the ppi (pixels per inch)?

Diagonal number of pixels: use Pythagoras:
The ACD 24": (1920^2 + 1200^2)/24 = 94.3 dpi
Code:
sqrt((width^2)+(height^2))/diagonal lengthThe ACD 24": (1920^2 + 1200^2)/24 = 94.3 dpi
I love that producer price index also comes up. Fewer people probably know about that than pixels per inch :\
Damn, I hoped no one would notice thatWas too busy adding the ACD calc
haha sorry
i'll edit my post to save you
Well... Not this way. The number of inches is a measure of the diagonal length of the screen, and not (if this formular would be correct) an area of the screen.
JavaScript:
Code:
var width = 1920;
var height = 1080;
var diagonal_inches = 24;
// result:
Math.sqrt((Math.pow(width,2)+Math.pow(height,2)))/diagonal_inches
