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 1 J4 and Fujifilm S4200 side-by-side from the front, back and top in their relative dimensions. Nikon 1 J4 has external dimensions of 100 x 60 x 29 mm (3.92 x 2.36 x 1.12″) and weighs 232 g (0.51 lb / 8.18 oz) (including batteries). Fujifilm S4200 has external dimensions of 118 x 81 x 100 mm (4.65 x 3.19 x 3.94″) and weighs 543 g (1.20 lb / 19.15 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon 1 J4 and the Fujifilm S4200. Nikon 1 J4 is clearly the smaller of the two cameras. Its body is 18mm narrower, 21mm shorter and 71mm thinner than Fujifilm S4200. As you can tell, actually this is not a fair size comparison since Fujifilm S4200 has a built-in lens but Nikon 1 J4 doesn't. Once you put a lens on 1 J4, its thickness will increase significantly.
Here is the back view size comparison of the Nikon 1 J4 and Fujifilm S4200.
Now lets look at the top view comparison of Nikon 1 J4 and Fujifilm S4200.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon 1 J4 is significantly lighter (311g ) than the Fujifilm S4200 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on 1 J4, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Nikon 1 J4 nor Fujifilm FinePix S4200 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Nikon 1 J4 and Fujifilm S4200's LCD screens have the same diagonal size of 3.00 inches.
