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 FX48 and Nikon S630 side-by-side from the front, back and top in their relative dimensions. Panasonic FX48 has external dimensions of 95 x 53 x 22 mm (3.74 x 2.09 x 0.87″) and weighs 150 g (0.33 lb / 5.29 oz) (including batteries). Nikon S630 has external dimensions of 58 x 97 x 26 mm (2.28 x 3.82 x 1.02″) and weighs 140 g (0.31 lb / 4.94 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic FX48 and the Nikon S630. Panasonic FX48 is 44mm shorter and 4mm thinner than Nikon S630 but it is also 37mm wider.
Here is the back view size comparison of the Panasonic FX48 and Nikon S630.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S630 is 10g lighter than the Panasonic FX48 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FX48 (Lumix DMC-FX40) nor Nikon Coolpix S630 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 S630's 2.70" LCD screen is slightly larger than Panasonic FX48's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
