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 ZS40 and Nikon S8200 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS40 has external dimensions of 111 x 64 x 34 mm (4.37 x 2.52 x 1.34″) and weighs 240 g (0.53 lb / 8.47 oz) (including batteries). Nikon S8200 has external dimensions of 104 x 59 x 33 mm (4.09 x 2.32 x 1.3″) and weighs 213 g (0.47 lb / 7.51 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic ZS40 and the Nikon S8200. Nikon S8200 is clearly the smaller of the two cameras. Its body is 7mm narrower, 5mm shorter and 1mm thinner than Panasonic ZS40.
Now lets look at the top view comparison of Panasonic ZS40 and Nikon S8200.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S8200 is 27g lighter than the Panasonic ZS40 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS40 (Lumix DMC-TZ60) nor Nikon Coolpix S8200 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
Panasonic ZS40 and Nikon S8200's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
