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 ZS100 and Nikon S6900 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS100 has external dimensions of 111 x 65 x 44 mm (4.37 x 2.56 x 1.73″) and weighs 312 g (0.69 lb / 11.01 oz) (including batteries). Nikon S6900 has external dimensions of 99 x 58 x 28 mm (3.9 x 2.28 x 1.1″) and weighs 181 g (0.40 lb / 6.38 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic ZS100 and the Nikon S6900. Nikon S6900 is clearly the smaller of the two cameras. Its body is 12mm narrower, 7mm shorter and 16mm thinner than Panasonic ZS100.
Here is the back view size comparison of the Panasonic ZS100 and Nikon S6900.
Now lets look at the top view comparison of Panasonic ZS100 and Nikon S6900.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S6900 is significantly lighter (131g ) than the Panasonic ZS100 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS100 (Lumix DMC-TZ100) nor Nikon Coolpix S6900 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 ZS100 and Nikon S6900's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon S6900 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. Panasonic ZS100's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to S6900.
