Hello guys,

I have an important question. I would like to know if fonts on Macbook Air 13 are smaller or bigger than fonts on Macbook pro 15 matte version.

Thank you very much

yes, good to hear if someone can help compare this, I used a mbp 13" before and now with a mba, the 15in looks good esp in mail/outlook, though I need some time to get used to this resolutions.

Should be about the same, both are 128 pixels per inch. http://en.wikipedia.org/wiki/List_of_displays_by_pixel_density

Or you could do the math yourself. MBP15: 15.4" diagonal, 1600x1050 display, MBA13: 13.3" diagonal, 1440x900.

Since c^2=a^2+b^2 and you know a & b, then easily figure out pixels per inch = (sqrt(a^2+b^2))/diagonal) where diagonal=13.3, a=1440, b=900 for the MBA13 and diagonal=15.4, a=1600, b=1050 for the MBP15 hires.

Wow really, so everything will be even smaller on macbook 15 matte. Thank you very much. Are you able to tell about how much if we talk in percents?

10%?

You can do the math for the DPI.

MacBook Air 13.3", 1,440 x 900 = 127.68 DPI
MacBook Pro 15.4" High Resolution, 1680 x 1050 = 128.65 PPI

Or you can use this handy dandy calculator.

DPI/PPI Calculator

But the results are the same.
