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 S9900 and Nikon S810c side-by-side from the front, back and top in their relative dimensions. Nikon S9900 has external dimensions of 112 x 66 x 40 mm (4.41 x 2.6 x 1.57″) and weighs 289 g (0.64 lb / 10.19 oz) (including batteries). Nikon S810c has external dimensions of 113 x 64 x 28 mm (4.45 x 2.52 x 1.1″) and weighs 216 g (0.48 lb / 7.62 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S9900 and the Nikon S810c. Nikon S810c is 2mm shorter and 12mm thinner than Nikon S9900 but it is also 1mm wider.
Here is the back view size comparison of the Nikon S9900 and Nikon S810c.
Now lets look at the top view comparison of Nikon S9900 and Nikon S810c.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S810c is significantly lighter (73g ) than the Nikon S9900 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix S9900 nor Nikon Coolpix S810c 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 S810c's 3.70" LCD screen is slightly larger than Nikon S9900's 3 screen.
On the other hand, Nikon S9900 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 S810c has a fixed type screen which provides almost no flexibility in shooting positions compared to S9900.
