Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Nikon L31 and Panasonic FP2 side-by-side from the front, back and top in their relative dimensions. Nikon L31 has external dimensions of 96 x 59 x 29 mm (3.78 x 2.32 x 1.14″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries).

Here is the back view size comparison of Nikon L31 and Panasonic FP2.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic FP2 is 9g lighter than the Nikon L31 but we don't think this will make a significant difference.
Unfortunately neither Nikon Coolpix L31 nor Panasonic Lumix DMC-FP2 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
