Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Nikon L31 and Kodak Z990 side-by-side from the front, back and top in their relative dimensions. Nikon L31 has external dimensions of 96 x 59 x 29 mm (3.78 x 2.32 x 1.14″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries). Kodak Z990 has external dimensions of 124 x 91 x 105 mm (4.88 x 3.58 x 4.13″) and weighs 445 g (0.98 lb / 15.70 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon L31 and the Kodak Z990. Nikon L31 is clearly the smaller of the two cameras. Its body is 28mm narrower, 32mm shorter and 76mm thinner than Kodak Z990.
Now lets look at the top view comparison of Nikon L31 and Kodak Z990.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon L31 is significantly lighter (285g ) than the Kodak Z990 which may become a big advantage especially on long walking trips.
Unfortunately neither the Nikon Coolpix L31 nor Kodak EasyShare Z990 (EasyShare Max) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Kodak Z990's 3.00" LCD screen is slightly larger than Nikon L31's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
