The ratio of the two areas is 1.50 i.e. the One has 50% more screen area.
No. Your measurements and calculations are wrong. From the Kobo specs:

Aura One: 7.8” HD Carta E Ink touchscreen, 1872 x 1404 resolution 300 dpi
Kobo Glo HD: 6” HD Carta E Ink touchscreen, 1448 x 1072 resolution 300 pixels per inch

From the specs by calculations:
Aura One screen is 6.24" x 4.68" = 29.2 square inches
Kobo Glo HD screen is 4.83"x3.57" = 17.2 square inches
Ratio (to two decimal places) = 1.69:1

Aura One pixels: 2,628,288
Kobo Glo HD pixels: 1,552,256
Ratio (to two decimal places) is 1.69:1


I can't see where you got your screen measurements and then you calculate incorrect screen areas (a screen that's 7.68x5.45 in. is 41.856 sq in, not 106.38 sq in).

The Aura One has slightly more than 69% more screen area than the Glo HD. Or, if you prefer, the Glo HD has just over 59% of the screen area of the Aura One.
