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 S4100 and Nikon P340 side-by-side from the front, back and top in their relative dimensions. Nikon S4100 has external dimensions of 95 x 57 x 20 mm (3.74 x 2.24 x 0.79″) and weighs (including batteries). Nikon P340 has external dimensions of 103 x 58 x 32 mm (4.06 x 2.28 x 1.26″) and weighs 194 g (0.43 lb / 6.84 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S4100 and the Nikon P340. Nikon S4100 is clearly the smaller of the two cameras. Its body is 8mm narrower, 1mm shorter and 12mm thinner than Nikon P340.
Here is the back view size comparison of the Nikon S4100 and Nikon P340.
Now lets look at the top view comparison of Nikon S4100 and Nikon P340.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S4100 is 194g lighter than the Nikon P340 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix S4100 nor Nikon Coolpix P340 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
Nikon S4100 and Nikon P340's LCD screens have the same diagonal size of 3.00 inches.
