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 S6300 and Nikon S6400 side-by-side from the front, back and top in their relative dimensions. Nikon S6300 has external dimensions of 94 x 58 x 26 mm (3.7 x 2.28 x 1.02″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries). Nikon S6400 has external dimensions of 95 x 58 x 27 mm (3.74 x 2.28 x 1.06″) and weighs 150 g (0.33 lb / 5.29 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S6300 and the Nikon S6400. Nikon S6300 is 1mm narrower and 1mm thinner than Nikon S6300 but they have the same height of 58mm.
Here is the back view size comparison of the Nikon S6300 and Nikon S6400.
Now lets look at the top view comparison of Nikon S6300 and Nikon S6400.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S6400 is 10g lighter than the Nikon S6300 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix S6300 nor Nikon Coolpix S6400 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 S6400's 3.00" LCD screen is slightly larger than Nikon S6300's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
