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 S6900 and Sony W830 side-by-side from the front, back and top in their relative dimensions. Nikon S6900 has external dimensions of 99 x 58 x 28 mm (3.9 x 2.28 x 1.1″) and weighs 181 g (0.40 lb / 6.38 oz) (including batteries). Sony W830 has external dimensions of 93 x 52 x 23 mm (3.66 x 2.05 x 0.91″) and weighs 122 g (0.27 lb / 4.30 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S6900 and the Sony W830. Sony W830 is clearly the smaller of the two cameras. Its body is 6mm narrower, 6mm shorter and 5mm thinner than Nikon S6900.
Here is the back view size comparison of the Nikon S6900 and Sony W830.
Now lets look at the top view comparison of Nikon S6900 and Sony W830.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W830 is significantly lighter (59g ) than the Nikon S6900 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix S6900 nor Sony Cyber-shot DSC-W830 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 S6900's 3.00" LCD screen is slightly larger than Sony W830's 2.7" screen.
Moreover, Nikon S6900 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Sony W830 has a fixed type screen which provides almost no flexibility in shooting positions compared to S6900.
