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 Panasonic SZ1 and Nikon S800c side-by-side from the front, back and top in their relative dimensions. 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). 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).
Below you can see the front-view size comparison of the Panasonic SZ1 and the Nikon S800c. 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 Panasonic SZ1 and Nikon S800c.
Now lets look at the top view comparison of Panasonic SZ1 and Nikon S800c.
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 Panasonic Lumix DMC-SZ1 nor Nikon Coolpix S800c 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.
