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 S800c and Panasonic SZ1 side-by-side from the front, back and top in their relative dimensions. Nikon S800c has external dimensions of 111 x 60 x 27 mm (4.37 x 2.36 x 1.06″) and weighs 184 g (0.41 lb / 6.49 oz) (including batteries). Panasonic SZ1 has external dimensions of 99 x 59 x 21 mm (3.9 x 2.32 x 0.83″) and weighs 131 g (0.29 lb / 4.62 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S800c and the Panasonic SZ1. Panasonic SZ1 is clearly the smaller of the two cameras. Its body is 12mm narrower, 1mm shorter and 6mm thinner than Nikon S800c.
Here is the back view size comparison of the Nikon S800c and Panasonic SZ1.
Now lets look at the top view comparison of Nikon S800c and Panasonic SZ1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic SZ1 is significantly lighter (53g ) than the Nikon S800c which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix S800c nor Panasonic Lumix DMC-SZ1 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 S800c's 3.50" LCD screen is slightly larger than Panasonic SZ1's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
