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 FH2 and Panasonic SZ3 side-by-side from the front, back and top in their relative dimensions. Panasonic FH2 has external dimensions of 94 x 54 x 19 mm (3.7 x 2.13 x 0.75″) and weighs 121 g (0.27 lb / 4.27 oz) (including batteries). Panasonic SZ3 has external dimensions of 95 x 56 x 22 mm (3.74 x 2.2 x 0.87″) and weighs 126 g (0.28 lb / 4.44 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic FH2 and the Panasonic SZ3. Panasonic FH2 is clearly the smaller of the two cameras. Its body is 1mm narrower, 2mm shorter and 3mm thinner than Panasonic SZ3.
Here is the back view size comparison of the Panasonic FH2 and Panasonic SZ3.
Now lets look at the top view comparison of Panasonic FH2 and Panasonic SZ3.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FH2 is 5g lighter than the Panasonic SZ3 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FH2 (Lumix DMC-FS16) nor Panasonic Lumix DMC-SZ3 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 FH2 and Panasonic SZ3's LCD screens have the same diagonal size of 2.70 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
