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 Samsung SL820 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). Samsung SL820 has external dimensions of 95 x 59 x 23 mm (3.74 x 2.32 x 0.91″) and weighs 168 g (0.37 lb / 5.93 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon L31 and the Samsung SL820. Nikon L31 has the same height with Samsung SL820. On the other hand, with a width of 96mm, it is 1 wider and also with a thickness of 29mm, it is 6mm thicker than Samsung SL820.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon L31 is 8g lighter than the Samsung SL820 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix L31 nor Samsung SL820 (IT100) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Samsung SL820'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.
