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 HZ30W 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 HZ30W has external dimensions of 107 x 61 x 28 mm (4.21 x 2.4 x 1.1″) and weighs 245 g (0.54 lb / 8.64 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon L31 and the Samsung HZ30W. Nikon L31 is 11mm narrower and 2mm shorter than Samsung HZ30W but it is also 1mm thicker.
Here is the back view size comparison of the Nikon L31 and Samsung HZ30W.
Now lets look at the top view comparison of Nikon L31 and Samsung HZ30W.
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 (85g ) than the Samsung HZ30W which may become a big advantage especially on long walking trips.
Unfortunately neither the Nikon Coolpix L31 nor Samsung HZ30W (WB600) 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
Samsung HZ30W'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.
