Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Nikon P1000 and Nikon S810c side-by-side from the front, back and top in their relative dimensions. Nikon P1000 has external dimensions of 146 x 119 x 181 mm (5.75 x 4.69 x 7.13″) and weighs 1415 g (3.12 lb / 49.91 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 Nikon P1000 and Nikon S810c. Nikon S810c is clearly the smaller of the two cameras. Its body is 33mm narrower, 55mm shorter and 153mm thinner than Nikon P1000.
Here is the back view size comparison of Nikon P1000 and Nikon S810c.
Now lets look at the top view comparison of Nikon P1000 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 (1199g ) than the Nikon P1000 which may become a big advantage especially on long walking trips.
Unfortunately neither Nikon Coolpix P1000 nor Nikon Coolpix S810c provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Nikon S810c's 3.7" LCD screen is slightly larger than Nikon P1000's 3.2" screen.
On the other hand, Nikon P1000 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 P1000.
