MacBook – What are the dimensions of the Mac Book Air 13″ screen

Every spec I've seen shows the diagonal measurement of 13.3". I'm interested in the actual width and height of the screen.

Thanks!

To calculate the screen dimension given the diagonal measurement and the resolution:

The 13.3" MacBook has a 1400 x 900 resolution. Assuming square pixel this gives us

which we can solve for x

The resulting value of x needs to be multiplied with 1400 and 900 to give the screen dimensions, in this case 11.2" x 7.2".
