Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Nikon L31 and Samsung ST600 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 ST600 has external dimensions of 104 x 60 x 20 mm (4.09 x 2.36 x 0.79″) and weighs 150 g (0.33 lb / 5.29 oz) (including batteries).
Below you can see the front view size comparison of Nikon L31 and Samsung ST600. Nikon L31 is 8mm narrower and 1mm shorter than Samsung ST600 but it is also 9mm thicker.
Here is the back view size comparison of Nikon L31 and Samsung ST600.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Samsung ST600 is 10g lighter than the Nikon L31 but we don't think this will make a significant difference.
Unfortunately neither Nikon Coolpix L31 nor Samsung ST600 provides any type of weather sealing in their body, 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 ST600's 3.5 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.
