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 FP3 and Panasonic FH3 side-by-side from the front, back and top in their relative dimensions. Panasonic FP3 has external dimensions of 99 x 59 x 19 mm (3.9 x 2.32 x 0.75″) and weighs 155 g (0.34 lb / 5.47 oz) (including batteries). Panasonic FH3 has external dimensions of 98 x 55 x 24 mm (3.86 x 2.17 x 0.94″) and weighs 165 g (0.36 lb / 5.82 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FP3 is 10g lighter than the Panasonic FH3 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FP3 nor Panasonic Lumix DMC-FH3 (Lumix DMC-FS11) 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 FP3's 3.00" LCD screen is slightly larger than Panasonic FH3's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
