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 S9100 and Panasonic FH10 side-by-side from the front, back and top in their relative dimensions. Nikon S9100 has external dimensions of 105 x 62 x 35 mm (4.13 x 2.44 x 1.38″) and weighs 214 g (0.47 lb / 7.55 oz) (including batteries). Panasonic FH10 has external dimensions of 94 x 54 x 18 mm (3.7 x 2.13 x 0.71″) and weighs 103 g (0.23 lb / 3.63 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S9100 and the Panasonic FH10. Panasonic FH10 is clearly the smaller of the two cameras. Its body is 11mm narrower, 8mm shorter and 17mm thinner than Nikon S9100.
Now lets look at the top view comparison of Nikon S9100 and Panasonic FH10.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FH10 is significantly lighter (111g ) than the Nikon S9100 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix S9100 nor Panasonic Lumix DMC-FH10 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 S9100's 3.00" LCD screen is slightly larger than Panasonic FH10's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
