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 Nikon A10 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). Nikon A10 has external dimensions of 96 x 59 x 29 mm (3.78 x 2.32 x 1.14″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S6900 and the Nikon A10. Nikon S6900 is 1mm shorter and 1mm thinner than Nikon A10 but it is also 3mm wider.
Here is the back view size comparison of the Nikon S6900 and Nikon A10.
Now lets look at the top view comparison of Nikon S6900 and Nikon A10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon A10 is 21g lighter than the Nikon S6900 but we don't think this will make a significant difference.
Unfortunately neither the Nikon Coolpix S6900 nor Nikon Coolpix A10 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 Nikon A10'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, Nikon A10 has a fixed type screen which provides almost no flexibility in shooting positions compared to S6900.
