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 Samsung NX100 and Nikon 1 S2 side-by-side from the front, back and top in their relative dimensions. Samsung NX100 has external dimensions of 120 x 71 x 35 mm (4.72 x 2.8 x 1.38″) and weighs 282 g (0.62 lb / 9.95 oz) (including batteries). Nikon 1 S2 has external dimensions of 101 x 61 x 29 mm (3.98 x 2.4 x 1.14″) and weighs 190 g (including batteries).
Below you can see the front-view size comparison of the Samsung NX100 and the Nikon 1 S2. Nikon 1 S2 is clearly the smaller of the two cameras. Its body is 19mm narrower, 10mm shorter and 6mm thinner than Samsung NX100.
Now lets look at the top view comparison of Samsung NX100 and Nikon 1 S2.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon 1 S2 is significantly lighter (92g ) than the Samsung NX100 which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since Samsung NX100 has an APS-C sized sensor and Nikon 1 S2 has a smaller 1' sensor, Nikon 1 S2's lenses for a similar focal length and aperture will generally be lighter and smaller than the Samsung NX100 lenses.
Weather Sealing
Unfortunately neither the Samsung NX100 nor Nikon 1 S2 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 Mirrorless Cameras with Weather Sealing

Samsung NX100 and Nikon 1 S2's LCD screens have the same diagonal size of 3.00 inches.
